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)
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) HopMAC|16 (Kangaroo Twelve) KMAC|16, 32 (Keccak) Poly1305|16
EXtendable-Output Function (XOF)
A secure hash that can produce output of any desired length.

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