QUESTION

How do I parse an x509 certificate and extract its key's signature algorithm?

Asked 2020-Apr-18 at 14:14

I have an x509 certificate as a file/byte array that I'd like to use to verify the signature provided in a CertificateVerify TLS message. I think I can use SecKeyVerifySignature once I've determined the certificate's key algorithm (SecKeyAlgorithm parameter) and initialized the signedData from the transcript hash (concatenated to the context string, etc.).

openssl x509 reports the certificate's key like

Subject Public Key Info:
    Public Key Algorithm: id-ecPublicKey
        Public-Key: (256 bit)
        pub:
            04:44:58:8c:d0:95:90:14:45:82:db:4f:56:41:7d:
            57:0e:f5:b4:d8:65:04:6c:21:5a:cd:1e:0e:87:10:
            f9:31:c6:fa:b9:ad:b3:a5:e1:df:9f:32:25:4b:a9:
            40:5c:d4:56:0d:bb:55:fd:f4:68:f9:4e:89:70:56:
            b9:1c:4a:ef:93
        ASN1 OID: prime256v1
        NIST CURVE: P-256 

I believe I can parse the certificate with the mechanism described here, eg.

CFDataRef certData = CFDataCreate(NULL, (const UInt8*) rawCert, len);
SecCertificateRef certificate = SecCertificateCreateWithData(NULL, certData);

And I think I can use SecCertificateCopyKey to extract the key, eg.

SecKeyRef key = SecCertificateCopyKey(certificate);

I can't, however, find a way to extract the key's signature algorithm (Public Key Algorithm). I found SecKeyIsAlgorithmSupported. Do I need to iterate over al the possible SecKeyAlgorithm constants to find the one that the key is using (ie. a SecKeyAlgorithm for id-ecPublicKey)?

ANSWER

Answered 2020-Apr-18 at 14:14

I misunderstood my own goals.

The CertificateVerify message provides a digest of the handshake up to that point. The server uses its certificate's private key to perform that signature. As indicated in the TLS 1.3 specification, the signature algorithm is part of the CertificateVerify structure

struct {
    SignatureScheme algorithm;
    opaque signature<0..2^16-1>;
} CertificateVerify;

I just need to extract it and convert it to a SecKeyAlgorithm. For example (with C++)

SecKeyAlgorithm keyAlgorithm;
// algorithm extracted from CertificateVerify
switch (algorithm) {
  case SignatureScheme::ecdsa_secp256r1_sha256:
    keyAlgorithm = kSecKeyAlgorithmECDSASignatureDigestX962SHA256;
    break;
  case SignatureScheme::rsa_pss_sha256:
    keyAlgorithm = kSecKeyAlgorithmRSASignatureDigestPSSSHA256;
    break;
  case SignatureScheme::ed25519:
  case SignatureScheme::ed448:
  default:
    throw std::runtime_error("unsupported peer cert type");
}

I can then confirm the certificate supports that algorithm

if (!SecKeyIsAlgorithmSupported(key, kSecKeyOperationTypeVerify, keyAlgorithm)) {
  CFRelease(publicKey);
  throw std::runtime_error("Unsupported signature scheme");
}

and finally perform the verification with the signature in the CertificateVerify and the compiled signed data from the handshake

CFErrorRef error;
bool signatureVerified = SecKeyVerifySignature(key, keyAlgorithm, toBeSignedData, signature, &error);
if (!signatureVerified) {
  CFRelease(error); // or use it
  throw std::runtime_error("Signature verification failed");
}
