Does RC4 algorithm work on Windows 2003 x64? RRS feed

  • Question

  • Hi, all!
    I use the Microsoft Enhanced Cryptographic Provider v1.0 with RC4 algorithm for encrypt/decrypt the data. 
    But after decrypt (CryptDecrypt function) the data is wrong - although the return result is TRUE. I try to use RC2, DES, 3DES 2 KEY, 3DES - they work correctly. 
    I check the using of Microsoft Base Cryptographic Provider v1.0 and Microsoft Strong Cryptographic Provider v1.0 with RC4 but there is no result.
    System is Windows 2003 EE x64 SP1 and I try to setup SP2 on one, but no result.
    Try to change the key length - uselessly...
    What else I can check?
