libmhash-dev 0.9.9.9-9build1 (amd64 binary) in ubuntu impish

 Mhash is a library that provides a uniform interface to a large
 number of hash algorithms. These algorithms can be used to compute
 checksums, message digests, and other signatures. The HMAC support
 implements the basics for message authentication, following RFC 2104.
 Mhash also provides several key-generation algorithms, including
 those of OpenPGP (RFC 2440). Further information is available at
 http://mhash.sourceforge.net/.
 .
 This package contains header files, the man page, and the static
 library.
