The Digital Signature Algorithm (DSA) is also a popular public-key technique, though it can only be used only for signatures, not encryption. A computation involving both the private key and the message itself is used to sign a message. The output is called a digital signature and is attached to the message. To verify the signature, the recipient does a computation involving the message, the purported signature, and the sender's public key. If the result is correct according to a simple, prescribed mathematical relation, the signature is verified to be genuine; otherwise, the signature is fraudulent, or the message may have been altered.  2, record 4, English, - public%2Dkey%20technique
