>Description:

man page shows for -c option: "Compare files to this md5 string."

This is misleading - the string needs to be in the same format as the digest command being used.

I suggest something like:

"Compare the files message digest to this string."

Also, suggest updating the date relating to known exploits.

>How-To-Repeat:

man sha1
man sha256
man sha512
man rmd-160
>Fix:

Apply attached patch suggestion
