WebCiphertext e. Decryption algorithm List and briefly define three uses of a public key cryptosystem. a. Encryption/decryption: the sender encrypts the message with the recipient's public key b. Digital signature: the sender signs the message with their own private key c. The two sides cooperate to exchange a session key. WebIf cipheris specified, it must be a ciphertext string of 1 to 373 characters. If simpleis specified, it must be a string of 1 to 255 characters. If neither ciphernor simpleis specified, you set a plaintext key string. For different algorithms, enter strings of any length in the specified range.
