UNIX-like crypt function

[p.v.bemmelen]

I am writing a program on a UNIX system that uses the crypt() function.
Now I want to port this program to MS-DOS, but the problem is that I don't
have a crypt() function, (source or object code).
Who can help me obtain a crypt() function ?? One that runs faster than the
standard unix one would also be welcome to speed up the UNIX version as well.
