Secure Hash Algorithm 2 (SHA-256 and SHA-384) — message digest Per CNSSP-15, the 256-bit elliptic curve (specified in FIPS 186-2), SHA-256, and AES with 128-bit keys are sufficient for protecting classified information up to the Secret level, while the 384-bit elliptic curve (specified in FIPS 186-2), SHA-384, and AES with 256-bit keys are ...

There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. These were also designed by the NSA. These were also designed by the NSA. SHA-3 : A hash function formerly called Keccak , chosen in 2012 after a public competition among non-NSA designers.
8.4 cpb on Core 2 for BLAKE-256; 7.8 cpb for BLAKE-512 BLAKE is a cryptographic hash function based on Daniel J. Bernstein 's ChaCha stream cipher , but a permuted copy of the input block, XORed with round constants, is added before each ChaCha round.

A Kerberos standard in 2005 recommended 4,096 iterations; [1] Apple reportedly used 2,000 for iOS 3, and 10,000 for iOS 4; [4] while LastPass in 2011 used 5,000 iterations for JavaScript clients and 100,000 iterations for server-side hashing. [5] In 2023, OWASP recommended to use 600,000 iterations for PBKDF2-HMAC-SHA256 and 210,000 for PBKDF2 ...
[2] Although hash algorithms, especially cryptographic hash algorithms, have been created with the intent of being collision resistant, they can still sometimes map different data to the same hash (by virtue of the pigeonhole principle). Malicious users can take advantage of this to mimic, access, or alter data. [3]
