The Data Encryption Standard algorithm on which Triple DES is based was first published in 1975. DES is a symmetric key block cipher. Symmetric key block ciphers process fixed-size blocks simultaneously using the same key to encrypt the data. The block size of a cipher refers to the number of bits that are processed together. darty usb wifi

WebThe CBC mode produces the same ciphertext whenever the same plaintext is encrypted using the same key and starting variable. The chaining operation makes the ciphertext blocks dependent on the current and all preceding plaintext blocks and therefore blocks can not be rearranged.
