Webplaintext: In cryptography, plaintext is ordinary readable text before being encrypted into ciphertext or after being decrypted. WebFigure 2 shows plaintext encrypted with the receiver's public key and decrypted with the receiver's private key. Only the intended receiver holds the private key for decrypting the ciphertext.
