WebTo reverse the encryption, Double-DES decryption uses key K2 first and then the key K1 after. This can also be expressed in math as it's shown and in the mathematical expression those that are inside the parenthesis are computed or processed first. The use of two independent keys, keys of one and keys of two, K1 and K2 are 112 bits long. WebDES is a symmetric key block cipher.
