DES and 3DES

Mar 21, 2013 at 7:38 AM
Just tried using this calculator and im confused on the DES/3DES feature. Forgive me for my lack of knowledge for the said encryption algo.

I do have the following data :

A KEY : E6EEEEEEEEEEEEEE D5DDDDDDDDDDDDDD
B KEY : 41AA5ECFE408C1E0 67B17E954463210F

DES_decrypt(B, A)

I need to decrypt this using DES only. I just would like to confirm that if i place this on the DATA and the KEY field, automatically it will do DES decryption?
