Hashes

Which one should I use?

MD5: 128-bit. Fast but broken; only OK for non-security checksums.
SHA-1: 160-bit. Also broken for collisions; avoid for new work.
SHA-256: 256-bit. Safe default for integrity checks & signatures.
SHA-512: 512-bit. Same family, larger digest, often faster on 64-bit CPUs.

For passwords, use bcrypt/argon2. These are too fast to be safe alone.

MD5 and SHA-1 are broken for collision resistance. Use SHA-256 or SHA-512 for security-sensitive checks.

Frequently asked questions

Which algorithms are available?: MD5, SHA-1, SHA-256, and SHA-512. MD5 and SHA-1 are no longer safe for cryptographic use.
Are files uploaded?: No. Files are read locally with the Web Crypto API.
