Hi,
I debugged it down to EnvelopedDataHelper.createCipher(ASN1ObjectIdentifier
algorithm); In my case the algorithm is 1.2.840.113549.3.2.
This value comes from the very beginning (I guess at the time of encryption),
from the encrypted document as "messageAlgorithm", as well as "keyEncAlg" which
in my case is 1.2.840.113549.1.1.1.
On line 179 it tries to find this algorithm from HashMap, but there is no such
algorithm. So it tries directly Cipher.getInstance("1.2.840.113549.3.2",
pkcs11prov); but it fails.
Yes, I know this is in BC code, but the algorithm strings come from iText code.
What should I do?
Best Regards, Valentin
