    Default Cryptograhic service provider failed

    I have an asp.net application that is using forms
    authentication and the encrypt/decrypt methods to encrypt
    the ticket. My application works perfectly on my test
    system. However, when moved over to production, I am
    receiving the following error:
    System.Security.Cryptography.CryptographicExceptio n:
    Cryptographic service provider (CSP) could not be found
    for this algorithm


    Searching has only revealed one other issue similar to
    this with a user using TripleDES encryption. The
    suggested resolution was to make sure that the high
    encryption pack was installed on the win2k server. I have
    confirmed that the high-encryption pack is installed on
    our production server. Anyone have any other ideas? TIA.

    Default Re: Cryptograhic service provider failed

    I have the same problem in certain cirstances. I would be very grateful
    if someone could explain me the reason for this.

    Meanwhile you could try the following:

    1. Set Impersonate to false in your Web.Config
    if this doesn't help, additionaly:
    2. Configure .NET framework to run under System-Account

    That helped solving the problem on my system,

    best regards
