Figure 3: Asymmetric encryption. In such a system, A can encrypt a message using the receiver’s B public key, but only the private key owned by B can decode the message. In a pair of keys, the public key is visible to all. The private key is the secret key and is primarily used for decryption or for encryption with digital signatures.Digital Signature Encryption. Sending an encrypted message is a safer choice than sending plaintexts. In public-key encryption, the sender’s public key is openly available and anyone can spoof their identity to send encrypted messages. The best way out of this is to use a Digital Signature along with encrypted messages.There are two primary types of encryption: symmetric and asymmetric. Symmetric encryption: Commonly used for private communication, data storage, and high-performance network connections. Asymmetric encryption: Used for secure email communication, safeguarding email communication, authenticating with digital signatures, and protecting online ...You can also use the operations in reverse to get a digital signature of the message. First, you use the decryption operation on the plaintext. For example, s = SIGNATURE(p) = p ^ d % z.
