About hash functions
MD5
128-bit hash. Fast but cryptographically broken — use only for checksums, not security.
SHA-1
160-bit hash. Deprecated for security use. Still found in legacy systems and Git.
SHA-256 / SHA-512
Current standards. SHA-256 used in Bitcoin, TLS, JWT. SHA-512 provides stronger collision resistance.
