GOST public key algorithm ENGINE donated to the OpenSSL by Cryptocom.

Very early version, doesn't do much yet, not even added to the build system.

+.TH MD5SUM 1 "29th November 1995" "Lankester et al." "Debian GNU/Linux"
+.SH NAME
+gostsum \- generates or checks GOST R34.11-94 message digests
+
+.SH SYNOPSIS
+.B gostsum
+[\-bv] [\-c [file]] | [file...]
+
+.SH DESCRIPTION
+.B gostsum
+generates or checks GOST hash sums. The algorithm to generate the
+is reasonably fast and strong enough for most cases. Exact
+specification of the algorithm is in
+.I GOST R34.11-94.
+
+Normally
+.B gostsum
+generates checksums of all files given to it as a parameter and prints
+the checksums followed by the filenames. If, however,
+.B \-c
+is specified, only one filename parameter is allowed. This file should
+contain checksums and filenames to which these checksums refer to, and
+the files listed in that file are checked against the checksums listed
+there. See option
+.B \-c
+for more information.
+
+.SS OPTIONS
+.TP
+.B \-b
+Use binary mode. In unix environment, only difference between this and
+the normal mode is an asterisk preceding the filename in the output.
+.TP
+.B \-c
+Check md5sum of all files listed in
+.I file
+against the checksum listed in the same file. The actual format of that
+file is the same as output of
+.B md5sum.
+That is, each line in the file describes a file. A line looks like:
+
+.B <hashsum>  <filename>
+
+So, for example, if a file was created and its message digest calculated
+like so:
+
+.B echo foo > hash\-test\-file; gost5sum hash\-test\-file
+
+.B gost5sum
+would report:
+
+.B d3b07384d113edec49eaa6238ad5ff00\  md5\-test\-file
+
+.TP
+.B \-v
+Be more verbose. Print filenames when checking (with \-c).
+
+.TP
+.B -t 
+Use test parameter set. 
+.B gostsum supports two sets of parameters (which are really parameters
+of GOST 28147-89 block cipher) specified in the IETF draft 
+.B draft-popov-cryptopro-cpalgs-02.txt
+By default, cryptopro paramset is used. This option enables use of test
+paramset as specified in appendices to the GOST.
+
+.SH BUGS
+
+This manpage is not quite accurate and has formatting inconsistent
+with other manpages.
+
+.B gostsum
+does not accept standard options like
+.BR \-\-help .
