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

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.

Name	Tag Size
CMAC	16 (AES)
HMAC	Depends on hash (Blake, Blake2, cShake, Keccak, MD4, MD5, RipeMD, Sha1, Sha2, Sha3, Shake, Whirlpool)

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

RegExp

RegExp escape string

Configuration (including collecting from environment variables)
Structured logging
Normalize stack entries, and stack traces across engines, with colors
