The TTY subsystem is central to the design of Linux, and UNIX in general. Unfortunately, its importance is often overlooked, and it is difficult to find good introductory articles about it. I believe that a basic understanding of TTYs in Linux is essential for the developer and the advanced user.

In the 220 milliseconds that flew by, a lot of interesting stuff happened to make Firefox change the address bar color and put a lock in the lower right corner. With the help of Wireshark, my favorite network tool, and a slightly modified debug build of Firefox, we can see exactly what's going on.

Last week at eurocrypt, a small group of researchers announced a fairly serious attack against the SHA-1 digest algorithm, which is used in many cryptosystems, including OpenPGP. The general consensus is that we should be moving in an orderly fashion toward the theater exits, deprecating SHA-1 where possible with an eye toward abandoning it soon (one point of reference: US gov't federal agencies have been directed to cease all reliance on SHA-1 by the end of 2010, and this directive was issued before the latest results). Since Debian relies heavily on OpenPGP and other cryptographic infrastructure, i'll be blogging about how Debian users can responsibly and carefully migrate toward better digests. This post focuses on some first steps for users of gpg, and for Debian Developers and Debian Maintainers in particular.

SHA-256 seems ok. Asymetric keys of at least 2048 bits are now the norm, and unfortunately I haven't found a PGP/GPG HOWTO/handbook/etc. that is up-to-date yet. As computing power increases, key size should increase too, and the docs have to be updated.
