DES (Data Encryption Standard) - Format HSM (Host Security Module)

1) I will be receiving a customer number data being stored in a database, where would crypto
User Password, and how to test it send the following example.
1.1) Where a need descryptografar information.
1.2) and elsewhere a cryptographic information.
Where the client uses the FK - Form from Key Components, based on DES (Data Encryption Standard), Format HSM (Host Security Module)
-> 56bit - Mode ECB

and in my case I intend to use Visual Studio 2008 VB.net

Example
1) The password would 57DB18B4AFDE4855 the cryptographic key crytografia would C44CEF2502C475E5 and password descrytografada
would be 5537, then as you would to run the above process successfully.

Simulation
Descryptografar: 57DB18B4AFDE4855 key: C44C EF25 02C4 75E5 Results: 5537


2) After you need the password 5537 to encrypt using the key crytografia C44C EF25 02C4 75E5 where the password crypto
be 57DB18B4AFDE4855, then as you would to run the above process successfully.

Simulation
Encryption: 5537 key: C44C EF25 02C4 75E5 Result: 57DB18B4AFDE4855


Overview

- DES (Data Encryption Standard) - 56bit Mode ECB

+ Encryption
- Key = C44CEF2502C475E5
- Data = 5537
- Result = 57DB18B4AFDE4855

+ Decryption
- Key = C44CEF2502C475E5
- Data = 57DB18B4AFDE4855
- Result = 5537
