Decoded request
A CSR requests a certificate. Issuer, certificate serial number, validity dates, and trust status are assigned when a certificate is issued and are not present here. Requested extensions may be changed by the certificate authority.
Choose one public certificate (.crt, .cer, .pem or .der). It is read only in your browser. Matching checks the public key; it does not verify certificate trust or revocation.
Choose a certificate to compare with this CSR.
Paste a Base64-encoded certificate, or one or more PEM certificates including their BEGIN and END CERTIFICATE lines. For a chain, keep the PEM boundaries between certificates. No CSR or private key is needed. Up to 20 certificates, 128 KB each, 1 MB total.
Ready for a certificate or chain.
Decoded certificates
Certificates appear in the order pasted, including duplicates. Displaying a chain does not validate its order, signatures, trust, expiration, or revocation.
