{"Image DocumentName": "Basic Terminology Plaintext Cryptographic system or cipher Ciphertext", "Image ImageDescription": "The original message. Ciphertext. The coded message. Enciphering or encryption. Process of converting from plaintext to ciphertext. Deciphering or decryption. Restoring the plaintext from the ciphertext. Cryptography. Study of encryption. Cryptographic system or cipher. Schemes used for encryption. Cryptanalysis. Techniques used for deciphering a message without any knowledge of the enciphering details. Cryptology. Areas of cryptography and cryptanalysis together. Before beginning, we define some terms. An original message is known as the. plaintext , while the coded message is called the ciphertext . The process of converting. from plaintext to ciphertext is known as enciphering or encryption ; restoring the. plaintext from the ciphertext is deciphering or decryption . The many schemes used. for encryption constitute the area of study known as cryptography . Such a scheme. is known as a cryptographic system or a cipher . Techniques used for deciphering. a message without any knowledge of the enciphering details fall into the area of. cryptanalysis . Cryptanalysis is what the layperson calls breaking the code. The areas. of cryptography and cryptanalysis together are called cryptology .", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
