libpurple-pwmd plugin repository created

Filed under: libpwmd, projects — bjk @ 9:11 pm

I’ve created a git repository libpurple-pwmd on GitLab. This is a plugin for libpurple (which is bundled with Pidgin) to retrieve account details from pwmd for any instant messaging protocol supported by libpurple. It requires the development version 3.x of Pidgin/libpurple but older and deprecated patches for Pidgin can be found here.

Update git repository paths

Filed under: projects — bjk @ 9:04 pm

I kinda messed up when importing projects from Gitorious to GitLab. Each project was in it’s own group rather than my username. So I’ve moved them to the bjk group. I’ve updated the git repository and ticket/issue links here on WordPress and also on SourceForge.

Pwmd and cipher iterations

Filed under: projects, pwmd — bjk @ 7:56 pm

I’m going to change how pwmd 3.0.x handles the “SAVE --cipher-iterations” command. Rather than make the parameter a count of the number of times to encrypt the XML data, it will be more like OpenPGP and to use it as the number of times to re-hash the passphrase that is used to encrypt the XML data.

Since the XML data is always encrypted using a 256-bit cipher key derived from the hash function, no matter the cipher, then it makes sense to spend time hashing the passphrase rather than encrypting the XML data.

The way it is now in pwmd 3.0.x is that an attacker could brute force the passphrase by taking the salt which is stored in the data file header and rehash a dictionary word the default number of times (1000 as it is) then test the hash against the generated hash at attack runtime. An attack like this is unlikely as far as I understand, but this attack may be much quicker than brute forcing the (hashed) 256-bit cipher key used to encrypt the XML even when there are no XML cipher iterations.

Update git repository from gitorious to gitlab

Filed under: projects — bjk @ 6:10 pm

Since Gitorious has been bought by GitLab the project repository links needed to be updated. Projects hosted by repo.or.cz will remain there for hopefully a long time. Thanks to all for their repository hosting services!
