ℹ️ Hash Algorithm Reference

ALGORITHM	OUTPUT	USE CASE	SECURITY
MD5	128-bit	File checksums	Broken
SHA-1	160-bit	Git commits	Weak
SHA-256	256-bit	Bitcoin, TLS	Strong
SHA-512	512-bit	Passwords	Strong
SHA-3-256	256-bit	Modern crypto	Strong
Keccak-256	256-bit	Ethereum	Strong
RIPEMD-160	160-bit	BTC addresses	Good

CRYPTO USE CASES

SHA-256: Bitcoin uses double-SHA256 for block hashing and Merkle trees
Keccak-256: Ethereum uses this for addresses, tx hashes, and smart contracts
RIPEMD-160: Bitcoin address = RIPEMD160(SHA256(pubkey))
SHA-512: Used in HD wallet key derivation (HMAC-SHA512)
SHA-3: NIST standardized post-SHA-2 algorithm
