Cryptography Quick Reference & Guidelines

Hash Functions (One-Way)

Cryptographic hash functions (SHA-256, SHA-512) take arbitrary input and produce a fixed-size digest. They are strictly mathematical one-way functions: you cannot mathematically "decrypt" or reverse a SHA-256 hash.

Symmetric Ciphers (Two-Way)

Ciphers like AES-256-GCM transform plaintext into ciphertext using a secret key and random initialization vector (IV). Authorized parties holding the key can reverse the operation through decryption.

Password Hashing vs Fast Hashes

Never use raw fast algorithms like MD5 or SHA-256 to store user passwords. Fast hashes can be brute-forced billions of times per second. Use slow, memory-hard key derivation algorithms like Argon2id or bcrypt instead.
