Cryptography computer definition
WebIn cryptology, the discipline concerned with the study of cryptographic algorithms, a cipher is an algorithm for encrypting and decrypting data. Symmetric key encryption, also called secret key encryption, depends on the use of ciphers, which operate symmetrically. WebPublic-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.

Perfect … WebIn cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information.
WebIn cryptography, plaintext is usually ordinary readable text before it is encrypted into ciphertext, or readable text after it is decrypted. Data input to or output from encryption … WebThe process of a confidentiality mode that transforms usable data into an unreadable form. The process of transforming plaintext into ciphertext using a cryptographic algorithm and key. The process of changing plaintext into ciphertext using a cryptographic algorithm for the purpose of security or privacy.
