Learn more advanced front-end and full-stack development at: https://www.fullstackacademy.com SHA-1 stands for Secure Hash Algorithm 1, a cryptographic hash function developed by the NSA that can be used to verify that a file has been unaltered. In this video, we go over the basic features and common implementations of cryptographic hash functions before diving into the inner workings of a Javascript implementation of the SHA-1 function. Although out of use now, walking through the hash function code provides valuable insight into how these algorithms work. Watch this video to learn: - What are Cryptographic Hash Functions - Practical uses for Cryptographic Hash Functions - How does SHA-1 work

SHA 512 (SECURE HASH ALGORITHM) 1) PAD WITH THE BITS 100..... UNTIL LENGTH OF PLAIN TEXT REACHES 128 LESS THAN MULTIPLE OF 1024 BITS 2) APPEND 128 BIT REPRESENTATION OF ORIGINAL PLAIN TEXT MESSAGE SO THAT LENGTH EQUALS TO MULTIPLE OF 1024 3) INITIALIZE 8 BUFFERS OF SIZE 64 BITS EACH TO STORE INTERMEDIATE RESULTS AND FINAL HASH CODE. 4) PROCESS EACH 1024 BIT BLOCK IN 80 ROUNDS. 5) OUTPUT IN BUFFERS IS THE 512 BIT HASH CODE

The MD5 algorithm is a widely used hash function producing a 128-bit hash value. Step 1. Append Padding Bits. The message is "padded" (extended) so that its length (in bits) is congruent to 448, modulo 512. ... Step 2. Append Length. ... Step 3. Initialize MD Buffer Step 4. Process Message in 16-Word Blocks. ... Step 5. Output.

The cryptographic hash function BLAKE Animation overview/visualization of how the hash function works Originally here: www.youtube.com/watch?v=PgpJNRnx6eY not sure why this was removed as its a great animation showing how the hash function works Full credits goes to the author(s) which are listed in the animation "BLAKE is one of the five hash functions in the final of the NIST SHA-3 Competition. BLAKE is one of the simplest designs to implement, and relies on previously analyzed components: the HAIFA structure and the ChaCha core function." https://131002.net/blake/ *Copyrights - Thought to be originally released as Public domain and used here in Fair Use

Modern cryptography depends on the existence of several special kinds of mathematical functions. One important kind is a one-way function. One-way functions are easy to compute but very hard for anyone to invert. Sometimes we refer to these functions as hash functions and their output as a hash. Cryptographic hash functions are a subset of hash functions that have special properties important to their use in cryptography.

A cryptographic hash function is a hash function which is considered practically impossible to invert, that is, to recreate the input data from its hash value alone. The input data is often called the message, and the hash value is often called the message digest or simply the digest. This video is targeted to blind users.

https://8gwifi.org/MessageDigest.jsp Secure Hash Standard Secure Hash Algorithm tutorial Algorithm can be described in two stages: preprocessing and hash computation. Preprocessing involves padding a message, parsing the padded message into m-bit blocks, and setting initialization values to be used in the hash computation. The hash computation generates a message schedule from the padded message and uses that schedule, along with functions, constants, and word operations to iteratively generate a series of hash values. The final hash value generated by the hash computation is used to determine the message digest. sha-1 algorithm sha-1 algorithm example sha-1 algorithm steps sha1 algorithm explanation with example sha1 hash sha1 hash algorithm sha1 tutorial

Since SHA1 has been broken, SHA256 is seen as one of the contenders to replace it. In this video I review why it might be needed and how it functions on a low and high level perspective by stepping through the algorithm with an example by converting abc to its digest. I did a similar explanation for SHA1 in another video so check that out. Ill also be doing some supplementary videos on the binary math...ill be having some fun with them :D Music Title Olympus by Ross Bugden https://www.youtube.com/watch?v=BnmglWHoVrk https://creativecommons.org/licenses/by/4.0/ Clips used One Piece film z - Eiichiro Oda, Tatsuya Nagamine Avatar the last Air Bender - Joaquim Dos Santos,Michael Dante DiMartino,Bryan Konietzko Ghost Pain - Masahiko Murata, Kazuchika Kise Terminator Genysis - Alan Taylor,Bill Carraro,Megan Ellison Phantasy Star Online - Keiichirô Kawaguchi,Kyohei Ito One Piece - Kōnosuke Uda, Eiichiro Oda,Alfred Kahn,Toei Animation,Yoshihiro Suzuki Animatrix- Peter Chung, Andrew R.
