Released<\/a><\/noindex> a new version of the oldest supported password cracking program John the Ripper 1.9.0-jumbo-1<\/a><\/noindex> (the project has been in development since 1996). Since the release of the previous version 1.8.0-jumbo-1, 4.5 years have passed, during which over 6000 changes (git commits) were made by more than 80 developers. Thanks to continuous integration<\/a><\/noindex>, including pre-validation of each change (pull request) on many platforms, during this time the developers recommended using the current edition from GitHub<\/a><\/noindex>, which was kept stable despite the changes made. The main code of the project is distributed<\/a><\/noindex> is under the GPLv2+ license, while the code of some components is under the BSD license. <\/p>\n

A notable feature of the new version is the introduction of FPGA support (in addition to CPU, GPU, and Xeon Phi). For ZTEX 1.15y<\/a><\/noindex>, consisting of 4 FPGA chips originally used primarily for Bitcoin mining, 7 types of password hashes are now implemented: bcrypt, classic descrypt (including bigcrypt), sha512crypt, sha256crypt, md5crypt (including Apache apr1 and AIX smd5), Drupal7, and phpass (used, in particular, in WordPress). Some of these are being implemented on FPGA for the first time. <\/p>\n

For bcrypt, the achieved performance of ~119k c\/s at 2^5 iterations («$2b$05») with a power consumption of about ~27 watts significantly surpasses results for the latest GPUs in terms of board performance, equipment cost, and power consumption. Additional support is also provided. of boards<\/a><\/noindex> of this type are also supported, verified for up to 16 boards (64 FPGA chips), controlled from a single Raspberry Pi 2. The usual functionality of John the Ripper is supported, including all password cracking modes and simultaneous loading of a large number of hashes. <\/p>\n

To enhance performance, a mask application (mode «—mask», including in combination with other modes) and comparison of computed hashes with those loaded on the FPGA have been implemented. In terms of implementation, many designs (for example, for sha512crypt and Drupal7<\/a><\/noindex>) use blocks consisting of multithreaded processor cores (soft CPU cores) interacting with cryptographic cores. This functionality was developed by Denis Burykin in coordination with other jumbo developers.<\/p>\n
