Decrypt a string at client ( VB 6 ) using DESCryptoServiceProvider

Hi I have used DESCryptoServiceProvider to encrypt DB password at the webservice i.e .net side. Well decryption is very easy at this end and which i have done successfully but i want decryption at my client i.e a VB 6 client. Is it possible to decrypt the password at VB Client. If Yes pls tell me how ..I am unable to do this.
