Certificate signature is a function of the signature algorithm indicated in the certificate itself, and is usually either SHA (SHA-1) or some other version of SHA (SHA-256, SHA-384, SHA-512).

 

  1. Can you tell which signature algorithm is indicated in the failing client certificate?

     

  2. Have you modified the ciphers in the client SSL profile?

     

  3. Have you modified the CA bundle in the client SSL profile?
