SSH Key Fingerprint Formatter
Parse an OpenSSH public key and show its SHA256/MD5 fingerprints.
About the SSH Key Fingerprint Formatter
Paste an OpenSSH public key line to see its key type, bit length, SHA256 fingerprint (Base64, as shown by ssh-keygen -lf), and legacy MD5 colon-hex fingerprint, computed locally with Web Crypto and a pure-JS MD5 implementation.
