Subject: Cracking 1Password Agile Keychain files with JtR!
Hi,
I have committed a patch (to magnum-jumbo repository) to crack
1Password Agile Keychain files.
Usage:
1. Run agilekc2john.py on 1Password Agile Keychain files.
2. Run JtR on output of agilekc2john.py
Performance on AMD X3 720 CPU,
$ ../run/john -fo:agilekeychain -t
Benchmarking: 1Password Agile Keychain PBKDF2-HMAC-SHA-1 AES
[32/64]... (3xOMP) DONE
Raw: 4473 c/s real, 1515 c/s virtual
1Password Agile Keychain is very similar (functionality / concept
wise) to OS X Keychain. It uses PBKDF2-SHA1 with 1,000 iterations and
AES-128 in CBC mode. Cracking speeds are almost same as OS X Keychain
cracking speeds. The format scales almost linearly with number of
cores (Thanks to Lukas!). This work is based on agilekeychain program
(https://bitbucket.org/gwik/agilekeychain code) written by Antonin
Amand.
GPU support is trvial to implement and will be done soon (expected
speedup > 100x).
