A .net Core port of BCrypt.net

If you're working on a .net core application and need to use BCrypt to store passwords, this is a quick and dirty port of BCrypt.net.

I have tested using this library on both the full .net 4.5 framework, as well as .net core RC1. It builds, compiles and the Unit tests pass.

It should be a drop-in replacement for BCrypt.net as the namespaces are unchanged.

A .net Core port of BCrypt.net, with some feature and security enhancements.

Compatible with both the full .net framework and .net core (Netstandard 1.3).

It should be a drop-in replacement for BCrypt.net as the namespaces are unchanged.

How to use

Standard use:

// hash and save a password
hashedPassword = BCrypt.Net.BCrypt.HashPassword(clearTextPassword);

// check a password
bool validPassword = BCrypt.Net.BCrypt.Verify(userSubmittedPassword, hashedPassword);

If you need to specify a different salt revision when generating hashes, you can pass in a SaltRevision parameter:

// hash and save a password
hashedPassword = BCrypt.Net.BCrypt.HashPassword(clearTextPassword, SaltRevision.Revision2A);

This is only recommended if you're dealing with legacy systems, otherwise you should use the default of 2b. Note that the salt algorithm does not change, it will generate a correct bcrypt hash in all known cases.


I did not write this library, I merely ported it to .net core. All credit goes to Ryan D. Emerle for porting BCrypt to .net in the first place.
