Mzsoft.BCrypt

BCrypt encryption utility implemented blowfish cipher trageted for .NET Standard. Supported platforms are .NET Core, .NET Framework, Mono, Xamarin.iOS, Xamarin.Android, Universal Windows Platform, Windows, Windows Phone also Windows Phone Silverlight

How to use it

Add reference to your code like this.

using Mzsoft.BCrypt;

To hash a password for the first time, call the HashPassword() method with a random salt, like this:

string pass = BCrypt.HashPassword("password", BCrypt.GenerateSalt());

To check whether a plain text password matches one that has been hashed previously, use the CheckPassword() method:

if (BCrypt.CheckPassword("password", pass)) 
{ 
  Console.WriteLine("Match"); 
} 
else 
{ 
  Console.WriteLine("Don’t Match"); 
}

The GenerateSalt() method takes an optional integer parameter that determines the computational complexity of the hashing:

string SaltStrong30 = BCrypt.GenerateSalt(30); 
string SaltStrong31 = BCrypt.GenerateSalt(31);

The amount of work increases exponentially (2**number). The default number is 10, and the valid range is 4 to 31.
