DES (Data Encryption Standard)
Standard, developed in the 1970s, to encrypt data using a private key algorithm. Vulnerable to brute-force attacks because of the relatively small, 56-bit size of its key (in 1999, a DES-encrypted message was cracked in just 22 hours using a distributed network of 100,000 PCs).
As a practical matter, anyone today who wants high security uses a more powerful version of DES called Triple-DES.
To start encrypting with Triple-DES, two 56-bit keys are selected. Data is encrypted via DES three times, the first time by the first key, the second time by the second key and the third time by the first key once more. This process creates an encrypted datastream that is unbreakable with today's code-breaking techniques and available computing power, while being compatible with DES.
The National Institutes of Standards and Technology considers DES an obsolute technology suitable only for legacy applications and today supports a new standard called Advanced Encryption Standard.

DES
by rellf
ok,
not as good as competition
try to use IP-1
its easier to use
if that doesnt work use E BIT-SELECTION TABLE
see ya
