NAME

     libmd — Message Digest functions from BSD systems

DESCRIPTION

     The libmd library provides message digest functions found on BSD systems either on their
     libc or libmd libraries and lacking on others like GNU systems, thus making it easier to
     port projects with strong BSD origins, without needing to embed the same code over and over
     again on each project.

     The library provides a compatibility interface for the Aladding Enterprises MD5
     implementation, but the interface is not exposed by default to avoid polluting the
     namespace.  The LIBMD_MD5_ALADDIN pre-processor variable needs to be defined to expose this
     interface.

     The library provides a pkgconf(1) entry named libmd.

HEADERS

HISTORY

     The libmd project started in the Debian GNU/kFreeBSD port as part of the libbsd library, as
     a way to ease porting code from FreeBSD to the GNU-based system.  It was subsequently split
     into a project created on Hadrons.Org (mirrored on FreeDesktop.Org) for other distributions
     and projects to use, and further extended to match the other BSD interfaces.

     It is now distributed as part of most non-BSD distributions
