1 This is the same as ecdsa-prime256v1-sha512.pem, except the signature is wrong.
3 Rather than encoding the signature into a DER-encoded Ecdsa-Sig-Value, it is a
4 concatenation of the r and s values. This is the format that WebCrypto uses for
5 ECDSA signature, but not what is used for digital signatures.
