I have a digital certificate based on ECC and I wanna use it to sign documents on Adobe Reader DC version 15.023.20070. The curve use is the P256 from the NIST.
My certificate is recognized when I add it in the Digital ID and Trusted Certificates menu.
When I try to sign a document and I choose this certificate, I have an error when I lauch the signature process. I can read the following message :
"Creation of this signature could not be completed
Size limit error
Error encountered while BER decoding"
The last message (BER decoding) seems to be linked with a communication to a smartcard but I have not a smartcard. My certificate is a P12 files protected by a password.
When I make the same signature process with a certificate based on RSA, I have not any issue.
Is there particular things to do to make a siganture with a certificate based on ECC?
