double DES is less secure than triple DES
triple DES is much slower than double DES
double DES is within the range of brute force attack. but triple DES is not in the range of brute force attack.
There's a project that's implemented Triple DES in C over at SourceForge called "Easy Triple DES." It's in alpha, but should at the very least give you a head start. (See link.)
There are a few disadvantages of Triple DES including processing times in which the more complex the longer it takes. Another disadvantage is when the file or hard drive crash, it's hard to recover.
For some time it has been common practice to protect and tansport a key for DES encryption with triple-DES (3DES). The function follows an encrypt-decrypt-encrypt (EDE) sequence. Decrypt sequence is simply the same (encrypt) operation with the keys reversed.
Easy! at first i thought double dees, however that is not right. The answer is Despair. Check out iriddler.com
fot the past 25 years single des algorithm was used. But now triple des is used in atm cards for the encryption and decryption.

The distance between Des Moines and Mexico City, Mexico is approximately 1,562 miles. Of course, the distance will be different for other locations in Mexico like Sinaloa or Aguascalientes. For example, the distance between Des Moines and Sinaloa is 1467 miles.
You can't, they are encrypted in the password file, typically using double DES or a higher security cypher system. If it is double DES and you have some way to get the NSA's Top Secret DES masterkey, then I guess you could. Its usually much easier to just use the reset password utility on the installation disk.
