2. Secure Hash Algorithms - Wikipedia

   en.wikipedia.org/wiki/Secure_Hash_Algorithms

   The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including:

3. BLAKE (hash function) - Wikipedia

   en.wikipedia.org/wiki/BLAKE_(hash_function)

   BLAKE was submitted to the NIST hash function competition by Jean-Philippe Aumasson, Luca Henzen, Willi Meier, and Raphael C.-W. Phan. In 2008, there were 51 entries. BLAKE made it to the final round consisting of five candidates but lost to Keccak in 2012, which was selected for the SHA-3 algorithm.

4. SHA-2 - Wikipedia

   en.wikipedia.org/wiki/SHA-2

   SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. [3] [4] They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.

5. Cryptographic hash function - Wikipedia

   en.wikipedia.org/wiki/Cryptographic_hash_function

   General-purpose ciphers tend to have different design goals. In particular, AES has key and block sizes that make it nontrivial to use to generate long hash values; AES encryption becomes less efficient when the key changes each block; and related-key attacks make it potentially less secure for use in a hash function than for encryption.

6. SHA-3 - Wikipedia

   en.wikipedia.org/wiki/SHA-3

   SHA-3 (Secure Hash Algorithm 3) is the latest [4] member of the Secure Hash Algorithm family of standards, released by NIST on August 5, 2015. [5] [6] [7] Although part of the same series of standards, SHA-3 is internally different from the MD5-like structure of SHA-1 and SHA-2.

7. Whirlpool (hash function) - Wikipedia

   en.wikipedia.org/wiki/Whirlpool_(hash_function)

   Whirlpool is a Miyaguchi-Preneel construction based on a substantially modified Advanced Encryption Standard (AES). Whirlpool takes a message of any length less than 2 256 bits and returns a 512-bit message digest. [3] The authors have declared that "WHIRLPOOL is not (and will never be) patented. It may be used free of charge for any purpose." [2]

8. How AOL uses SSL to protect your account

   Encryption scrambles and unscrambles your data to keep it protected. • A public key scrambles the data. • A private key unscrambles the data. Credit card security. When you make a purchase on AOL, we'll only finish the transaction if your browser supports SSL.

9. EdDSA - Wikipedia

   en.wikipedia.org/wiki/EdDSA

   Ed25519 is the EdDSA signature scheme using SHA-512 (SHA-2) and an elliptic curve related to Curve25519 [2] where =, / is the twisted Edwards curve + =, = + and = is the unique point in () whose coordinate is / and whose coordinate is positive.
