WebDES (Data Encryption Standard) is a symmetric block cipher standardized in FIPS 46-3 (now withdrawn). It has a fixed data block size of 8 bytes. Its keys are 64 bits long, even though 8 bits were used for integrity (now they are ignored) and do not contribute to security. The effective key length is therefore 56 bits only.

WebFIPS Pub. 81 [4] specifies the ECB, CBC, CFB, and OFB modes of the Data Encryption Standard (DES). FIPS Pub. 46-3 [3] approves the seven modes that are specified in ANSI X9.52 [1]. Four of these modes are equivalent to the ECB, CBC, CFB, and OFB modes with the Triple DES algorithm (TDEA) as the underlying block cipher; the other . 1 WebThere are two phases to the use of DES encryption. The first is the generation of a DES_key_schedule from a key, the second is the actual encryption. A DES key is of type DES_cblock. This type is consists of 8 bytes with odd parity. The least significant bit in each byte is the parity bit.
