Hi,
first of all - SHA1 is a hashing algorithm - no encryption. Hashing is a non-reversible process, which is fine for passwords.
The corresponding class is called SHA1Managed - i would recommend moving to SHA256Managed if you can.
Both support a ComputeHash method that takes a byte[] and returns a byte[].
Especially for passwords i would recommend using PasswordDeriveBytes (1.1) or Rfc2898DeriveBytes (2.0).
have a look at them in the docs - if you have further questions - feel free to ask.

Hi, I was reading that md5 is not that secure and that sha-1 or whilpool or ripemd-160 were better solutions. I'm using asp.net and I want to encrypt the password. Where can I find a sample code for that with sha-1. I can't seem to find one.
Thanks Francisco
