Free Online WebRTC Certificate Fingerprint Calculator

Calculate WebRTC/DTLS certificate fingerprints from an X.509 PEM certificate. Supports SHA-256 and more, and generates an SDP-ready a=fingerprint line. Runs locally in your browser with zero uploads.

Input Certificate (PEM)

Paste your PEM certificate (with BEGIN/END CERTIFICATE) or choose a certificate file.

Notes

WebRTC DTLS fingerprints are typically a hash of the certificate DER bytes and are advertised in SDP as a=fingerprint:sha-256 <fingerprint>.
If Web Crypto is unavailable (crypto.subtle.digest), the tool cannot compute fingerprints.
Hashing a certificate does not expose private keys, but certificates may contain identifying metadata. Handle with care.
