Unfortunately this seems to be the original BSD license with the "obnoxious advertising clause". I don't like it, and it isn't even GPL compatible.
No, it isn't - it says "must be identified as blahblah", not "if you advertise you must say blahblah".
It doesn't use the term "advertising", but it says:
: License is also granted to make and use derivative works provided : that such works are identified as "derived from the RSA Data : Security, Inc. MD5 Message-Digest Algorithm" in all material ^^^^^^^^^^^^^^^ : mentioning or referencing the derived work. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Which seems even broader. It means concretely, among other situations, if I write a CGI program that uses this code and use it on a web site (which I do), I have to put this boilerplate on this web site (possibly even on each page that links to it, as in "referencing") which is where most users certainly care very little about it.
This may not be the intention of this license, but lacking a definitive (and liable) legal advice to the contrary, I assume this might be required.
Since these files come from the OpenBSD libc, and OpenBSD ships GNU GPL'd binaries, I'm _pretty_ sure of this.
The GPL contains a special exception for system libraries.
