I have two certificates, physically residing on the same (Belgian) government issued smart card. One is labeled "Authentication" (Intended usage: sign transaction), and the other is labeled "Signature" (Intended usage: sign document). I have been trying to add a signature to a pdf document in Acrobat Pro XI (trial) on WIndows 8 Home (64 bit). It works perfectly with the "Authentication" certificate, but all attempts with the "Signature" certificate yield the following error:
Error encountered while signing:
The Windows Cryptographic Service Provider reported an error:
Access was denied because of a security violation.
Error Code: 2148532330
The only relevant difference between both certificates that I have been able to spot, is in the "key usage" field of the certificate ("sign transaction" versus "sign document"). Any thoughts on what might be wrong?
Thanks.
