Frequently Asked Questions

What is a hash?

A cryptographic hash is a fixed-length string derived from input data using a mathematical function. The same input always produces the same hash, but different inputs produce different hashes.

Which hash algorithm should I use?

Use SHA-256 or SHA-512 for security-sensitive applications. SHA-1 is outdated but still used for checksums. Never use SHA-1 for password hashing — use bcrypt or Argon2 instead.

Is MD5 supported?

MD5 is not available via the Web Crypto API as it's considered insecure. We support SHA-1, SHA-256, SHA-384, and SHA-512.
