I did answer this before but it doesn't seem to have made it to the list. Are you assuming the result is a text string and using/copying it with something like strlen()? If so that will fail if the result contains an embedded null. RSA_public_encrypt() with PKCS#1 padding contains a random element so you will get different results for the same plaintext.
