Encrypt with password

Discussion in 'ASP .Net Security' started by Bishoy George, Oct 20, 2005.

  1. I want a class for encryption that takes a password or key and a string and
    use the key to encrypt the string, so the decrypt method of that class will
    never decrypt the encrypted string without giving it the same key.

    Thanks,
    Bishoy

    Dear Bishoy George,

    You have told like;

    > http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnadvne
    > http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetse


    The Pages are very much there, but only thing you have not copied
    completely. The URLs are continued in the next line. Please copy the URL
    completely and try this time.

    I am little bit busy with my work, but never the less, I will let you know
    some material on Assymmetric Encryption

    Bye
