Thanks for that....
how does Padding fit into this
I have been using RSA_NO_PADDING with
RSA_public_encrypt....
man pages say this is not such a good idea
but my call to RSA_public_encrypt fails if i use any
of the other PADDING options....i am assuming this is
because my msg(to be encrypted) is as big as the key.
What are the dangers/consequences of using
RSA_NO_PADDING ?
