Default SHA1 Encryption/Decryption help


Can someone help me in decrypting a string that has been encrypted in the manner below?:

=== Start Encryption ===
public static byte[] EncryptPassword(string password)
    UnicodeEncoding encoding = new UnicodeEncoding();
    byte[] hashBytes = encoding.GetBytes( password );

    // compute SHA-1 hash.
    SHA1 sha1 = new SHA1CryptoServiceProvider();
    byte[] cryptPassword = sha1.ComputeHash ( hashBytes );

    return cryptPassword;
=== End Encryption ===

Can't be done.

SHA1 is a hashing algorithm, the whole point of which is to provide a one-way hash of an input string (byte array, actually).

Please don't cross post. Most of us monitor more than one forum category and we'll see your question. See this thread.
