研究方向

從報告中的 signer_certificate.verify(certificate.public_key) 呼叫開始,將 RSA 憑證的詳細資訊與 issue 中 ECC 憑證的詳細資訊進行比較。追蹤 Ruby OpenSSL binding 如何處理簽章演算法 rsassaPss 和金鑰 id-ecPublicKey,然後重現未知簽章演算法錯誤。當報告的憑證驗證路徑不再意外拒絕此演算法時,即視為完成。

描述

Hi everyone, I don't know much about SSL understanding and I have a question because I try to verify a certifcate.
I hope someone can help me and/or maybe guide me to a solution.

Context occurs on a process of strong user authentication where I can receive either an old certificate or a new one. My code has to work with both of them.
I think I have to verify the signature of a certificate to provide this strong integrity.

I don't have any issue with the old certificate which is based on RSA Keys, but I got one with the new certificate where it is an ECC key.
At the moment I have no choice but to bypass the check on the new certificate.

The old certificate has the following lines in it (I have omitted some lines) :

Certificate:
    Data:
        Version: 3 (0x2)
        Signature Algorithm: sha256WithRSAEncryption
        Subject Public Key Info:
            Public Key Algorithm: rsaEncryption
                RSA Public-Key: (2048 bit)
                Modulus:
                    -----
                Exponent: 65537 (0x10001)

The new certificate has the following lines in it :

Certificate:
    Data:
        Version: 3 (0x2)
        Signature Algorithm: rsassaPss         
         Hash Algorithm: sha256
         Mask Algorithm: mgf1 with sha256
          Salt Length: 0x20
         Trailer Field: 0xBC (default)
        Subject Public Key Info:
            Public Key Algorithm: id-ecPublicKey
                Public-Key: (256 bit)
                pub:
                    --------
                ASN1 OID: prime256v1
                NIST CURVE: P-256

I usually execute the following command to verify the certificate : signer_certificate.verify(certificate.public_key)

I get unknown signature algorithm when I try to use this command on the new certificate.
