Finaldata Enterprise 3.0 Serial 104

This project’s the foundation of a new feature set for the next release. The TLS 1.2 proxy behaviour that’s presumed here is the following: the proxy forwards the client’s ClientHello message to the server and inspects the resulting ServerHello and certificates. Based on the name in the certificate, the proxy may drop out of the connection (i.e. allow the client and server to communicate directly) or may choose to interpose itself, answering the client with an alternative ServerHello and the server with an alternative ClientKeyExchange, negotiating different encrypted sessions with each and forwarding so that it can see the plaintext of the connection. In order to satisfy the client in this case the client must trust the proxy, but that’s taken care of in the enterprise setting by installing a root CA on the client. (Or, in Syria, by hoping that users click through the the certificate error.) Protocol buffers pretty much hit the sweet spot of complexity and capability. (See XML and ASN.1 for examples of attempts which missed.) I have the beginnings of a protocol buffer compiler for Haskell that I wrote for internal apps. Now that the C/Java/Python versions are out, I should probably clean that up and put it on Hackage. But every coder should consider protocol buffers for their serialisation needs from now on. ASN.1 DER is designed to be a distinguished encoding, i.e. there should be a unique serialisation for a given value and all other representations are invalid. As such, numbers are supposed to be encoded minimally, with no leading zeros (unless necessary to make a number positive). Feitian doesn’t get that right with this security key: numbers that start with 9 leading zero bits have an invalid zero byte at the beginning. Presumably, numbers starting with 17 zero bits have two invalid zero bytes at the beginning and so on, but I wasn’t able to press the button enough times to get such an example. Thus something like one in 256 signatures produced by this security key are invalid. See ProFTPd for a nicer code of operating system dependent code.

The MPLAB Snap In-Circuit Debugger/Programmer allows affordable, fast and easy debugging and programming of PIC, dsPIC and AVR flash MCUs and MPUs, using the powerful graphical user interface of MPLAB X Integrated Development Environment (IDE). The MPLAB Snap can be connected to a design engineer’s computer using a High-Speed USB 2.0 interface and can be connected to the target via an 8-pin Single In-Line (SIL) connector. The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming (ICSP). It has all the speed and features entry-level users need to quickly debug their prototype.

one thing that i hadn’t expected is that the serial protocol that apc provide is so simple. i’ve been through a lot of code for a lot of devices in the past two years and the simple serial protocol from apc is the nicest i’ve seen. apc’s tech support say that the protocol was designed by an actual hardware engineer. i wonder if they’re talking about the guy who did the asic for the apc time machine upss?
i’ve finally finished the work on the c/java/python implementations of the finaldata enterprise 3.0 protocol. i’ve been working on this on and off for the past year and i’ve been both excited and a little bit worried about the amount of work i’m committing to. i’m pretty happy with the way it turned out.
our move to a pre-computed hash for certificate serial numbers has meant that we can’t use the old serial number formats. the hash is always 128 bits and always has the same format as the hostname, which means it can be included in the subjectaltname extension in certificates for up to the last 128 dns hostnames. we’ve also moved to using cose for cbor instead of cbor-like formats, which makes it easier for us to work with the authentication process.
the webauthn api doesn’t actually make web browsers do anything. the web browser doesn’t do anything. its the user’s device that does the work. in a previous version of pkion we attempted to do the user side of things by supporting a pki store. the user’s pki store is just a directory that contains the root certificate for the site and the public keys for each web browser. we also added an api that let you add or remove certificates from the pki store. so when you connect to a site, pkion would check if you had that site’s certificate in your user pki store. when we moved to a pre-computed hash for certificate serial numbers we had to change to a new serial number format. so now we use a digest of the hostname and the serial number, so a site like has its own serial number, and hashed with sha1 of its hostname it becomes something like 4fb8df2f9df9c7b1a8448f8e2d1e4a30f82ab2e8a. this is used by pkion to sign the certificates and gives the same information to the user as before, but because the serial number is now computed, it can be reused for every request.
