Which Hash Should You Use?
- SHA-256 — the industry standard. Use this for integrity checks, file verification, and API signatures.
- SHA-512 — stronger output; good when hardware support exists.
- SHA-384 — used in TLS and some government standards.
- SHA-1 — legacy. Still seen in old systems but no longer considered secure against collision attacks.
Important: Hashes are one-way. You can't "decrypt" a hash back to the original text. For passwords, always use a purpose-built algorithm like bcrypt or Argon2 — not a plain hash.
