Hashes FAQ

Which hash algorithm is best for new projects?

SHA-256 is the most broadly compatible default. SHA-3 and BLAKE3 are strong modern alternatives when your environment supports them.

Should I still use MD5 or SHA-1?

Use MD5 or SHA-1 only for legacy compatibility and non-security checks. They should not be used for signatures, certificates, passwords, or new security designs.
