Asking for help, clarification, or responding to other answers. I'm having trouble hitting all keys of a chord together. 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. openssl dgst -verify foo.pem expects that foo.pem contains the "raw" public key in PEM format. 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).
