Algorithm
Output size & notes
SHA-1
160 bits (40 hex chars) — considered broken for security use, but still seen in legacy systems
SHA-256
256 bits (64 hex chars) — the current standard default; used in Git, TLS certificates, Bitcoin
SHA-384
384 bits (96 hex chars) — a truncated variant of SHA-512, sometimes used in TLS
SHA-512
512 bits (128 hex chars) — strongest option here, often faster than SHA-256 on 64-bit systems
