Frequently Asked Questions
Is SHA-1 still safe to use?
SHA-1 is considered cryptographically broken for security-critical purposes like certificates, but it's still fine for checksums, git object IDs, and non-adversarial integrity checks.
Does this upload my text anywhere?
No — the hash is computed locally using your browser's native Web Crypto API. Nothing you type ever leaves your device.
What's the difference between SHA-1 and SHA-256?
SHA-256 produces a longer, more collision-resistant digest and is the recommended choice for anything security-sensitive; SHA-1 is shorter and faster but weaker.
