    Help diagnosing "The selected certificate has errors: Invalid Signature"

    Hugh Kelley

      I am unable to sign a PDF using a new certificate I have received.  I have tried Acrobat X and XI.  I have also tried importing both the root and issuing CAs as trust anchors.  Those certs seem to verify fine.  This issue appears to be with the signature on my cert.

       

      My suspicion is that the issue stems from the issuing CA's use of the "AlternateSignatureAlgorithm", 1.2.840.113549.1.1.10 RSASSA-PSS, for my user cert.  Acrobat does not seem to recognize this algorithm.  It simply lists the OID value when I look at the signature algorithm under details.

       

      The certificate is validated fine using certutil.exe and works fine when I use it for client SSL authentication.  I am using Windows 7 and have tried both 32 and 64 bit PCs.

       

      Has anyone experienced this before?

            Hi Hugh,

             

            As you figured out the certificate was using a signature algorithm that Acrobat did not understand. The "signature algorithm" is a composite of the the digest algorithm (e.g. sha1), and the encryption algorithm (e.g. RSA). Acrobat understands the following digest algorithms; MD5, SHA-1, RIPEMD-160, SHA-256, SHA384, and SHA512. As far as encryption algorithms go, it understands DSA and RSA. Just to make things a little more complicated, version XI also can handle elliptic curve, but versions 6 thru 10 were limited to DSA & RSA. If you are using a digital ID created with the DSA encryption algorithm then the only digest algorithm Acrobat can use with is SHA-1. Just like you saw sha1RSA, you could also use a digital ID with the sha1DSA signature algorithm. If you are using RSA then it will pair with all six digest algorithms I noted above (e.g. sha256RSA).

             

            The Probabilistic Signature Scheme is not something Acrobat understands at all.

             

            Steve
