Hi,
You simply can't guess the padding mode if you don't know it in advance.
Imagine the security consequences if this was possible : it would mean
that an attacker can have information about the clear text without
having access to the private key!!
Cheers,

How can I tell what the padding mode was before I attempt to decrypt data.
For example, when I use
RSA_private_decrypt(encsize,
encdata,
decdata,
privkey,
RSA_PKCS1_PADDING)
I sometimes (but not always) get the following error:
error:0407106B:rsa routines:RSA_padding_check_PKCS1_type_2:block type is
not 02
