C# sha1 encrypt decrypt

WebAs encryption is a hashing based on nonlinear functions, there is no decryption method.This means that to retrieve the password corresponding to a sha-1 hash, there is no choice but to try all possible passwords!. Technically, this operation would take several thousand years, even on the most powerful computers in the world. WebJava代码使用PBKDF2和HMAC/SHA1 1，C#代码是一种基于PBKDF1的算法。对于PBKDF2，在C#代码中，PasswordDeriveBytes必须替换为Rfc2898DeriveBytes (默认为HMAC/SHA1 1)。注意，.NET实现需要最少8字节的盐。另外，Java使用32字节键，C#代码使用16字节键。
