James T. Murphy III's logo


My name is James T. Murphy III. I am currently a mathematics Ph.D. student at the University of Texas in Austin. I am a Carnegie Mellon University mathematics graduate who received a B.S. in Computational Finance and M.S. in Mathematical Sciences in 2014. Gautam Iyer was my Master's thesis adviser. I have strong interest in mathematics, specifically in probability and stochastic analysis. I am also interested in computer science, cryptography, and economics.


For those conscious to security, you may directly download my OpenPGP public keys. My keys are also published on MIT's key server.

If you are not familiar with PGP, it is used for signing and encrypting data to increase security. I encourage reading the wiki to improve your understanding. Visit the GNU Privacy Guard website to download GnuPG, a complete and free implementation of the OpenPGP standard.


My preferred method of contact is PGP signed and encrypted text-only email. Email addresses that you can reach me at are contained in the user ids of my PGP keys listed above. Please do not send unencrypted email. Any email I send not signed by one my PGP keys listed above should be considered as satirical for legal purposes.

I have written a few articles. They are mostly about how to do math and computer stuff. I wrote them because I find myself constantly web searching and recompiling data in order to do simple tasks. They now serve as a reference for me and others. If you find a mistake in one, feel free to email me about it.

Supported Projects/Organizations

Strong Cryptography

This site uses (requires) strong modern cryptography. In general, seeing the little lock and "https" in the URL are not enough to know you are connecting to a website securely. In order to maintain maximum compatibility when talking to outdated servers, even modern browsers will give no warning to the user if a website is using completely broken cryptography. Qualys SSL Labs has written a server test to grade a website's https configuration. If a website gets less than an A, you should be worried about trusting them with any sensitive data. This domain received an A+ on 03/02/16.

Tor Relay

I am currently operating the tor relay nicknamed "intfxdx". You can check its status on Globe or Atlas. See the official documentation on tor relays for more information. I started running the relay on 01/07/15 and I plan to run it indefinitely.

Mirror of torproject.org

I am currently maintaining mirror of torproject.org: https and http. I am offering an http mirror (instead of requiring https, like I do for this domain) because many people for whom tor would be of critical importance do not have access to means of connecting securely. The https version is served with a certificate that is valid for intfxdx.com, and hence your browser may warn you that something fishy is going on, or that an attacker may be trying to steal your data. Thus, if you choose to download tor from my mirror, I strongly recommend that you verify the PGP signature of any file you download prior to running it. This ensures that even if you do not trust me or my server, you can still be sure your downloads are legitimate.

Onion Service

This site is mirrored as a tor onion service: http://iwjke47bybivwh6i.onion (requires a tor capable browser to view). See the official documentation on onion services for more information. I believe that offering an onionsite version of my website is important because it (1) promotes public awareness of tor and tor onion services, (2) provides background chatter so that activists, free-thinkers, and political dissidents who really need anonymity aren't the only ones hosting onion services, and (3) shows how easy it is for anyone to set up an onion service.
