Released<\/a> The new version of the oldest supported password cracking program, John the Ripper 1.9.0-jumbo-1, is available. (The project has been in development since 1996.) In the project page<\/a> addition, the source code and ready-made builds for Windows are available for download.<\/p>\n

<\/noindex><\/p>\n

It is noted that 4.5 years have passed since the release of version 1.8.0-jumbo-1, during which more than 6000 changes (git commits) were made by over 80 developers. During this time, developers recommended using the current edition from GitHub<\/a>, which maintained a stable condition despite the changes thanks to continuous integration<\/a>, which includes preliminary verification of each change (pull request) on many platforms. A feature of the new version is the introduction of FPGA support in addition to CPU, GPU, and Xeon Phi.<\/p>\n

\nFor boards ZTEX 1.15y<\/a>, including 4 FPGA chips each and originally used mainly for Bitcoin mining, now support 7 types of password hashes: 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 implemented on FPGA for the first time. For bcrypt, the achieved performance of ~119k c\/s at 2^5 iterations («$2b$05») with a power consumption of around 27 watts significantly surpasses the results for the latest GPUs when considering cost per board, hardware price, and per watt. Other types are also supported. of boards<\/a> from boards of this type, verified with up to 16 boards (64 FPGA) controlled from a single Raspberry Pi 2. Supports the usual functionality of John the Ripper, including all password cracking modes and the simultaneous loading of a large number of hashes. To speed up operations, the use of a mask (\"--mask\" mode, including in combination with other modes) and comparison of computed hashes with those loaded on the FPGA side is implemented. In terms of implementation, many designs (for example, for sha512crypt and Drupal7<\/a>) 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
