Detailed explanation-1: -The science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext. The formulas used to encode and decode messages are called encryption algorithms, or ciphers.
Detailed explanation-2: -In cryptography, plaintext is usually ordinary readable text before it is encrypted into ciphertext, or readable text after it is decrypted.
Detailed explanation-3: -Encryption is the method of converting a plaintext into a cipher text so that only the authorized parties can decrypt the information and no third parties can tamper with the data. Unencrypted usually refers to data or information that is stored unprotected, without any encryption.
