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 SHA-1 is outdated but still used for checksums.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.
