Frequently asked questions

How long is a SHA-1 hash?

40 hexadecimal characters, or 160 bits.

Is SHA-1 still safe to use?

No — SHA-1 is broken for security because practical collisions exist. Use SHA-256 or SHA-512 instead. SHA-1 is fine for non-security checksums and Git object IDs.

Where is SHA-1 still used?

Git uses SHA-1 to identify commits and objects, and some legacy systems still rely on it for integrity checks.
