    Certificate Decoder & Chain Checker

    Decode PEM certificates, check chain order, and verify signatures — in your browser.

    Paste a certificate or a whole chain and read every X.509 field, see the chain order corrected with the reason it was wrong, and get a real signature verdict on each link — verified, failed, or not-checked with the algorithm named. Hand-rolled DER parser, Web Crypto verification, zero uploads.
