CipherTest: fix RSA encrypt and decrypt meaning
The getEncryptKey and getDecryptKey methods should be for returning
normal enciphering and deciphering keys respectively. RSA keys can be
used for two different purposes as outlined by PKCS 1 and are called
"block types."
The block type 1 is used for generating signatures. A signature is
created by preparing a block type 1 plaintext then using the PrivateKey
to "decrypt." Then later on anyone can verify the signature by using the
matching PublicKey to "encrypt" and get the PKCS 1 formatted plaintext
back.
The block type 2 is used for enciphering a message to a recipient. The
PublicKey is used to encrypt the message and later on only those
possessing the PrivateKey can decrypt and read the plaintext.
