CryptAPI is a C# library which has the purpose to provide backward compatibility with the unix's C crypt() function for encrypting a string using a salt. This salt will indicate the type of algorithm that will be used to encrypt such string. Since neither mono nor the .NET framework provide this compatibility the main purpose of CryptAPI is to give programmers the proper library so that, if needed, they can integrate it to their development.

We have integrated almost all the algorithms used in different Linux/Unix distributions and have ported the following encryption algorithms based on salt:

LM (No salt needed).
NTLM (No salt needed).
DES.
Extended DES.
FreeBSD's Short MD5.
FreeBSD's Long MD5.
Short Blowfish.
Long Blowfish.
The library itself was programmed by porting code from unmanaged code to managed code.

As of today, CryptAPI provides the following:

Encryption of string using proper salt.
Encrypted password recognition based on salt.
Service provider to facilitate developer usage.
Portable and modifiable managed code in C#.
