Cryptography computer definition
WebIn cryptography, an encryption key is a variable value that is applied using an algorithm to a string or block of unencrypted text to produce encrypted text or to decrypt encrypted text. The length of the key is a factor in considering how difficult it will be to decrypt the text in a given message. WebThe process of a confidentiality mode that transforms usable data into an unreadable form.
