Best Password Practices (Create A Secure Password)
Learn how to create a secure password at https://digitoolbag.com/secure-password/ Don't forget to subscribe for more videos like this: https://digitoolbag.com/ytsub In this video, I'm going to teach you how to create a secure password. When it comes to your password security, you cannot be safe enough. Follow along and learn how to create a secure password. No sane person would ever like someone else reading his or her email. Or for that matter some other person using her password and breaking into a financial institution. You should, therefore, choose a strong, secure password in such a manner that would be a hard nut to crack for others and easy for you to remember. The more random and mixed-up you make it, the harder it is for others to crack. Mind you, if your password is compromised, the password crackers will even take over your identity. A password, if too short, is vulnerable to attack if an attacker gets hold of the cryptographic hash of the password. Present-day computers are fast enough to try all alphabetic passwords shorter than seven characters. We can call a password weak if it is short or is a default, or which can be rapidly guessed by searching a subset of all possible passwords such as words in the dictionary, proper names, words based on the username or common variations on these themes. On the other hand, a strong password would be sufficiently long, random, or which can be produced only by the user who chose it, so that ‘guessing’ for it will require too long a time. For maximum security, the user should follow some simple guidelines: 1) Passwords should preferably be at least 12 characters long. 2) Passwords should contain a mix of numbers, upper case & lower case letters, and special characters (%&[email protected]!). 3) Passwords should not contain a dictionary word from any dictionary, be it French, Spanish, medical, etc. 4) Each password should be different from the user’s User-ID and any permutation of that User-ID. 5) New passwords and old passwords should differ by at least 3 characters. 6) Avoid picking names or nicknames of people, pets, or places, or personal information that can be easily found out, such as your birthday, address etc. 7) It’s wise to stay away from common keyboard sequences, such as dfgh678 or abc345. 8) Never form a password by appending a digit to a word. That can be easily guessed. 9) Avoid writing your password down or storing it on your computer. 10) Never share your password with anyone else. Once you finalize your password, I’d recommend you use a service like LastPass or OnePass to keep your passwords secure. Now that we’ve covered that, let’s discuss two amazing tools you can use to help create a secure password. The first tool we’re going to cover is PasswordsGenerator.net which helps generate secure passwords for you and then will give you a phrase to help remember it. You do not “have to” use the password generator but I do recommend that you test the strength of your password you want to use and never settle for anything below “Strong/Very Strong”. Password Strength Checker This is one of my newest additions to my “Best Free Online Tools” list! PasswordMeter.com is (in my opinion) one of the websites everyone should use! It does a complete test on your password and will check the strength or complexity of your password. The stronger or more complex the password, the more secure! I tested the password I got from PasswordsGenerator.net and you can see below how Password Meter will test your password. Now you have the resources … So go get secure! P.S. I know there are some people who still feel the need to keep a “log book” of their login/password information as a physical copy. If you feel like you would rather do that, here is a cool password logbook that should help you. https://www.amazon.com/Password-Book-Create-Passwords-Organized/dp/1793371601 I hope this has helped you.

Java Program: Strong Password Generator i.e Wordpress Password Generator
In this Java Program, a model like a password generator used in WordPress is being developed. Firstly, the user is asked how long he/she would want the password to be and then a random password of that length is generated. The program takes all the capital or block letters and adds then with the small letters and symbols and then users a random object to randomly select these characters from a StringBuilder object and then upon getting the exact length of the password, the password is displayed. An online password check is also used to check how strong the password is and it happens to be very strong.

Symmetric Key and Public Key Encryption
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

JMS240: Secure User Authenticaion and Cryptographically Secure Tokens in PHP
A common problem in PHP is creating cryptographically secure tokens for user authentication. Think "remember me" and password reset features. Functions like rand(), mt_rand() and uniqid() simply aren't enough. And, without "resource-improbable" tokens... it's only a matter of time for a hacker to break your authentication and get int your application. Fortunately, PHP 5.6 and 7 have added the necessary functions for us to creating cryptographically secure tokens, prevent timing attacks and mitigate data hacks.

Java: Random vs SecureRandom
Every service that has a login mechanism should also have the option to reset the password. But how to do it right? Subscribe: https://www.youtube.com/c/KacperSzurekEN?sub_confirmation=1 Password reset functionality usually works more or less like this. The user provides the email address associated with the account on the website. At this point, the server checks whether such user exists in the database. If so - it generates a unique string, which is then saved and sent in an email. Then the user opens the email and clicks on the link that contains this unique key. The server verifies if a unique string exists in the database - and if everything is correct, you can change the password. So how to generate this unique string? Probably we will think of using the Random class that lets us generate unique sequences of numbers. The Java Random class is a pseudo random number generator. This means that based on a small amount of information - the so-called seed, it generates deterministically consecutive pseudo-random numbers. The seed can be defined by the user - or like in our case, set automatically by Java. So it is enough to guess what seed was used to be able to generate the next token on your own computer.

How secure is 256 bit security?
Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Home page: https://www.3blue1brown.com/ Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives the desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

It includes the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 as well as RSA’s MD5 algorithm. Python also supports the adler32 and crc32 hash functions, but those are in the zlib module. One of the most popular uses of hashes is storing the hash of a password instead of the password itself. Of course, the hash has to be a good one or it can be decrypted. Another popular use case for hashes is to hash a file and then send the file and its hash separately. Then the person receiving the file can run a hash on the file to see if it matches the hash that was sent. If it does, then that means no one has changed the file in transit Cryptographic hashes are used in day-day life like in digital signatures, message authentication codes, manipulation detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more. They are also used in sending messages over a network for security or storing messages in databases. There are many hash functions defined in the “hashlib” library in python. Some of the most used hash functions are: MD5: Message digest algorithm producing a 128 bit hash value. This is widely used to check data integrity. It is not suitable for use in other fields due to the security vulnerabilities of MD5. SHA: Group of algorithms designed by the U.S's NSA that are part of the U.S Federal Information processing standard. These algorithms are used widely in several cryptographic applications. The message length ranges from 160 bits to 512 bits. Functions associated : encode() : Converts the string into bytes to be acceptable by hash function. digest() : Returns the encoded data in byte format. hexdigest() : Returns the encoded data in hexadecimal format. ----------------------------------------------------------------------------------------------------------- Hope This Video Is Helpful For You ► Connect with me! ◄ Facebook - http://bit.ly/2tbOg3b Google+ - http://bit.ly/2jrWz6g Instagram - http://bit.ly/2tbR14z Reddit - https://bit.ly/2J5Vqfm ★★★Watch my most recent videos playlist★★★ Kali Linux - https://goo.gl/36M3JD Deep Web - https://goo.gl/7ueKNh Python Coding - https://goo.gl/dCtyrS Java Coding - https://goo.gl/oxFo8W Basic Computer - https://goo.gl/kwFXM3 Hacking - https://goo.gl/vjT916 Games Benchmark - https://goo.gl/eshw3T Gaming - https://goo.gl/mLuQwf Notepad Tricks -https://goo.gl/3uapMJ CMD Tricks - https://goo.gl/x1KH8C Facebook Tricks - https://goo.gl/1JV9Fz Problem Solved - https://goo.gl/eJwjXq Gmail Tricks - https://goo.gl/fSpbaB And talking about subscribing, please subscribe to my channel, if you enjoyed this video and want more how-to, Thanks so much for watching!

Tricks to hack hashed passwords
As we know, hash function/algorithm is used to generate digest/checksum of data. Hash function is not reversible. However, it can be hacked, and it is easy. In this video, I will use some websites to crack hashed passwords manually. You can see how easy to hack hashed passwords if hackers use powerful computer or clusters of computers to hack our passwords. They would crack millions every second. Do not assume your passwords are safe as long as they are hashed into non-reversible digests.

Un-f*$#ing Cloud Storage Encryption - Adam Everspaugh
Source: https://archive.org/details/ShmooCon_2019 Individuals, enterprises, and government agencies encrypt information before uploading to commodity cloud storage systems like Box or Amazon’s S3 to gain strong security in the event the storage provider is compromised. Regulations like HIPAA and PCI (and good security hygiene) require that encryption keys be rotated periodically. The current schemes in use for rotating encryption keys are either infeasible or insecure as we discuss in this presentation. We describe attacks against the current scheme and present two new encryption schemes that improve the security of key rotation offering different security and performance trade-offs. Dr. Adam Everspaugh (@AdamEverspaugh) is a cryptographer and software engineer. He researches and presents on topics including oblivious password hardening, secure random number generators, and updatable encryption. Adam is a security engineer for Coinbase, and a cryptographic advisor to Keeper Security (password management service), and the distributed app platform Mainframe.com.

#HITB2017AMS D2T1 - Vulnerabilities In Android Password Managers - Huber, Arzt & Rasthofer
There are different policies for the generation of secure passwords. However, one of the biggest challenges is to memorize all these complex passwords. Password manager applications are a promising way of storing all sensitive passwords cryptographically secure. Accessing these passwords is only possible if the user enters the correct master password, which is the only password that he needs to remember. At first, the requirements for a password manager application seem simple: Storing the passwords of a user in a secure and confidential way. On the other hand, the stakes are high. If the protection breaks, the attacker gets access to all of the user’s passwords. We therefore investigated what the reality looks like for mobile password manger applications on Android. Applications vendors advertise their password manager applications as “bank-level” or “military-grade” secure. However, can users be really sure that their secrets are stored in a secure way? Or can they be accessed by an attacker? We will show the most common implementation pitfalls and design failures as well as how we exploited them in the aforementioned Android password managers. We will show that a faulty concept will break the confidentiality even without root privileges. Furthermore, we explain countermeasures and best practice approaches to avoid these vulnerabilities. === Stephan Huber is a security researcher at the Testlab mobile security group at the Fraunhofer Institute for Secure Information Technology (SIT). His main focus is Android application security testing and developing new static and dynamic analysis techniques for app security evaluation. He found different vulnerabilities in well-known Android applications and the AOSP. In his spare time he enjoys teaching students in Android hacking. --- Steven is a currently a researcher at the Fraunhofer Institute for Secure Information Technology (SIT) in Darmstadt. He graduated from TU Darmstadt in computer science and IT Security. Steven is one of the core maintainers of the Soot open-source compiler framework and the FLOWDROID open-source static data flow tracker. His main interests center around research and hacking for (mobile) security, as well as static and dynamic program analysis. Together with his colleagues, he leads the hacking team of SIT. --- Siegfried Rasthofer is a vulnerability- and malware-researcher at Fraunhofer SIT (Germany) and his main research focus is on applied software security on Android applications. He developed different tools that combine static and dynamic code analysis for security purposes and he is the founder of the CodeInspect reverse engineering tool. He likes to break Android applications and found various AOSP exploits. Most of his research is published at top tier academic conferences and industry conferences like DEF CON, BlackHat, AVAR or VirusBulletin.
