SQL CLR - Invalid length for a Base-64 char array or string

Question

I've created a user defined function and executed. It returns the below error message. Need your support.

public partial class UserDefinedFunctions
{

    [Microsoft.SqlServer.Server.SqlFunction]
    public static SqlBoolean SqlFunctValidateUserCred() 
    {
            bool verify = Crypto.VerifyHashedPassword("test", "test1");
            return verify;
    }
}

Error:

Msg 6522, Level 16, State 2, Line 11 A .NET Framework error occurred during execution of user-defined routine or aggregate "SqlFunctValidateUserCred": System.FormatException: Invalid length for a Base-64 char array or string.
