Cryptography computer definition

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. Webcryptography uses multiple hash functions to secure data. Some of the most popular cryptographic hashes include the following: Secure Hash Algorithm 1 ( SHA-1) Secure Hash Algorithm 2 (SHA-2) Secure Hash Algorithm 3 ( SHA-3) MD2 MD4 MD5 Message-digest hash functions like MD2, MD4 and MD5 help hash digital signatures.
