Cryptography simple definition
WebEncryption is a form of data security in which information is converted to ciphertext. Only authorized people who have the key can decipher the code and access the original … WebEncryption – definition and meaning Encryption in cyber security is the conversion of data from a readable format into an encoded format. Encrypted data can only be read or processed after it's been decrypted. Encryption is the basic building block of data security.
