I need a way to reversibly anonymize IPv4, IPv6, and MACs, and so I found CryptopANT: https://ant.isi.edu/software/cryptopANT/index.html
Haven't done a lot of C in years and so I need a troubleshooting refresh. Am I missing any steps? Is there something more versatile than CryptopANT out there by now?
To install and use the scramble_ips binary on Debian 10, I did this:
- Downloaded the tarball
- Unzipped to /usr/local/src
- ./configure, make, and make install
So far so good. Output from the above is included below. Now I gotta actually compile the binary, right? I do the gcc and get the "undeclared" issue. Ok so I've got some issue with regex4, probably a version thing since the last CryptopANT release was almost 3 years ago. Thing is I've got no clear idea where to start. Did I miss a configure or make step? Was there another step? Is it dependencies? Where should these have been declared?
Let me know if I need to include anything else.

----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the 'LD_RUN_PATH' environment variable
during linking
- use the '-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to '/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
