Hi Herbert,
The second call to ProcessBlock is using 'cipher' when presumably
'cipher1' is intended. Also you are using 'blockLength' for the length
in that call, when it should just be 'encrypted.length'.
Also, what are you trying to do with the data here, encrypt/decrypt it
or sign/verify it? Please check that you don't have the public and
private keys mixed up in the Init calls.
Regards,
Pete Dettman
