Absolutely. Also, it probably is in your best interest to advertise details of your cryptography. What data is shared with whom, what algorithms are used, etc.; if you're doing something more exotic / low-level, Alice-Bob diagrams can be helpful. I'm not sure what other people do but when looking at security-sensitive software, the first thing I do is look for the cryptographic setup and research it.
