It is an unfortunate source of confusion that there is an encryption algorithm called RSA, and also a signature algorithm called RSA, and both kinds of RSA can share the same key structure; even more confusingly, a lot of people erroneously refer to signatures as "encrypting with the private key", which is wrong and makes the overall picture especially obscure.

You had better keep signatures and encryption separate (and there are good reasons for that). ( procedural ). Matrix of Functions to Function that returns a Matrix. Verification Failure Signature. Why should one not use the same asymmetric key for encryption as they do for signing? OpenSSL dgst authentication failure. The digest functions also generate and verify digital signatures using message digests. In particular, using the value friendencryptedpassword.txt and the public key friendpublickey.txt, both of which being public (since they are sent "on the wire"), it is trivial to rebuild friendpassword.txt, and I bet that's not what you would want to happen. The immediate reason of the verification failure is that the signature was generated over friendencryptedpasswordbase64.txt, but you try to verify it over phase2friendencryptedpassword.txt, which has not the same contents. What you obtain with that command-line is not encryption; it rather is a half-signature (the input file, friendpassword.txt, is taken "as is" as if it was a hash value, embedded in a "PKCS#1 v1.5 type 1 padding", and subject to the RSA core modular exponentiation).
