§ One-way fingerprints
Four digests, one paste.
Hashes turn arbitrary input into a fixed-length fingerprint. Handy for file integrity checks, cache keys, and generating short identifiers.
Should I still use MD5 or SHA-1?
Not for security. Both are cryptographically broken. They are still fine for non-adversarial checksums — cache keys, deduplication, integrity of non-critical files. For anything security-sensitive, use SHA-256 or SHA-512.
Why are my hashes different from a CLI tool?
Most likely a trailing newline. `echo "foo"` adds \n; this tool hashes the exact characters you paste. Use `printf "foo"` or strip trailing newlines before comparing.
Does it upload my text?
No. Hashing is done locally with crypto-js. Nothing leaves your browser.
