I have found the reason for the problem. Deep inside my program was a bug that
switched modulus and exponent, so I set the wrong values to n and e.
I've fixed the bug and also removed the leading 00 so that I get a good 128
byte long modulus and a 4 byte long exponent.
If I call RSA_verify I get now the reason 155 as error description.
If I call RSA_public_decrypt I get a NULL pointer access violation.
What can I do now?
Could the NULL pointer exception be because of missing structure entries to RSA?
I just do
RSA_new()
and the set only n and e.

Maybe the leadings 00 is the problem with both?

Hello,
> RSA_NO_PADDING leads to the same error.
Exactly, this fails on first stage.
Maybe you can send (n,e) pair ?
