Checksum/Hash

A checksum; can be used to prevent/identify accidental changes. A hash; maps some data to another, often used for hash tables, or to speed up comparison.

Secure Hash

Cryptography hash functions that have the properties:

Finding an input string that matches a hash value (pre-image) is hard
Finding a pair of messages that generate the same hash value (collision) is hard

† No longer considered cryptographically safe

Key Derivation Function (KDF)

A cryptographic algorithm that derives one or more secret keys from a secret value. Can be used to stretch keys (make them longer), or obtain a key in a particular format (eg making a key a fixed length)

HKDF
PBKDF2 pbkdf2_hmac_sha1, pbkdf2_hmac_sha256, pbkdf2_hmac_sha512

Message Authentication Code (MAC)

Also known as an authentication tag, a short piece of information to authenticate a message. Protect integrity, and authenticity.

EXtendable-Output Function (XOF)

A secure hash that can produce output of any desired length.

Name|Capacities|Optional parameters -------|-----------|------------------- Ascon-Xof, Ascon-XofA|256|digest size cShake|128, 256|digest size, function name, customization KangarooTwelve|128|digest size, customization KmacXof|128, 256|digest size, key, customization ParallelHashXof|128, 256|block size, digest size, customization Shake|128, 256|digest size TupleHashXof|128, 256|digest size, customization TurboSHAKE|128, 256|digest size, customization

Pseudorandom number generators (PRNG)

Marsaglia - possible to calculate in your head
Middle-Square - in practice flawed since the period is often short and will converge towards the same number or loop after repeated times
MSVC
RANDU - a famously bad PRNG
