Subject: Re: 1.7.9-jumbo-6
All -
Here's a draft of the change list that I think is far more suitable for
the announcement than CHANGES-jumbo was. Please take a look and let me
know ASAP if you spot any errors or crucial omissions. Thanks.

OpenMP support for previously supported hashes that lacked it:
* Mac OS X 10.4 - 10.6 salted SHA-1 (magnum)
* DES-based tripcodes (Solar)
* Invision Power Board 2.x salted MD5 (magnum)
* HTTP Digest access authentication MD5 (magnum)
* MySQL (old) (Solar)
CUDA support for:
* phpass MD5-based "portable hashes" (Lukas)
* md5crypt (FreeBSD-style MD5-based crypt(3) hashes) (Lukas)
* sha512crypt (glibc 2.7+ SHA-crypt) (Lukas)
* sha256crypt (glibc 2.7+ SHA-crypt) (Lukas)
* Password Safe (Lukas)
* WPA-PSK (Lukas)
* Raw SHA-224, raw SHA-256 [inefficient] (Lukas)
* MSCash (DCC) [not working reliably yet] (Lukas)
* MSCash2 (DCC2) [not working reliably yet] (Lukas)
* Raw SHA-512 [not working reliably yet] (myrice)
* Mac OS X 10.7 salted SHA-512 [not working reliably yet] (myrice)
OpenCL support for:
* phpass MD5-based "portable hashes" (Lukas)
* md5crypt (FreeBSD-style MD5-based crypt(3) hashes) (Lukas)
* sha512crypt (glibc 2.7+ SHA-crypt) (Claudio)
- suitable for NVIDIA cards, faster than the CUDA implementation above
* bcrypt (OpenBSD-style Blowfish-based crypt(3) hashes) (Sayantan)
- pre-configured for AMD Radeon HD 7970, will likely fail on others unless
WORK_GROUP_SIZE is adjusted in opencl_bf_std.h and opencl/bf_kernel.cl;
the achieved level of performance is CPU-like (bcrypt is known to be
somewhat GPU-unfriendly)
* MSCash2 (DCC2) (Sayantan)
- with multi-GPU support (even AMD+NVIDIA mix), benefits from OpenMP
* Password Safe (Lukas)
* WPA-PSK (Lukas)
* RAR (magnum)
* MySQL 4.1 double-SHA-1 [inefficient] (Samuele)
* Netscape LDAP salted SHA-1 (SSHA) [inefficient] (Samuele)
* NTLM [inefficient] (Samuele)
* Raw MD5 [inefficient] (Dhiru, Samuele)
* Raw SHA-1 [inefficient] (Samuele)
* Raw SHA-512 [not working properly yet] (myrice)
* Mac OS X 10.7 salted SHA-512 [not working properly yet] (myrice)
Several of these require byte-addressable store (any NVIDIA card, but
only 5000 series or newer if AMD/ATI). Also, OpenCL kernels for "slow"
hashes/non-hashes (e.g. RAR) may cause "ASIC hang" on certain AMD/ATI
cards with recent driver versions. We'll try to address these issues in
a future version.
AMD XOP (Bulldozer) support added for:
* Many hashes based on MD4, MD5, SHA-1 (Solar)
Uses of SIMD (MMX assembly, SSE2/AVX/XOP intrinsics) added for:
* Mac OS X 10.4 - 10.6 salted SHA-1 (magnum)
* Invision Power Board 2.x salted MD5 (magnum)
* HTTP Digest access authentication MD5 (magnum)
* SAP CODVN B (BCODE) MD5 (magnum)
* SAP CODVN F/G (PASSCODE) SHA-1 (magnum)
* Oracle 11 (magnum)
Other optimizations:
* Reduced memory usage for raw-md4, raw-md5, raw-sha1, and nt2 (magnum)
* Prefer CommonCrypto over OpenSSL on Mac OS X 10.7 (Dhiru)
* New SSE2 intrinsics code for SHA-1 (JimF, magnum)
* Smarter use of SSE2 and SSSE3 intrinsics (the latter only if enabled in the
compiler at build time) to implement some bit rotates for MD5, SHA-1 (Solar)
* Assorted optimizations for raw SHA-1 and HMAC-MD5 (magnum)
* In RAR format, added inline storing of RAR data in JtR input file when the
original file is small enough (magnum)
* Added use of the bitslice DES implementation for tripcodes (Solar)
* Raw-MD5-unicode made "thick" again (that is, not building upon "dynamic"),
using much faster code (magnum)
* Assorted performance tweaks in "salted-sha1" (SSHA) (magnum)
* Added functions for larger hash tables to several formats (magnum, Solar)
Other assorted enhancements:
* New option: --dupe-suppression (for wordlist mode) (magnum)
* New option: --loopback[=FILE] (implies --dupe-suppression) (magnum)
* New option: --max-run-time=N for graceful exit after N seconds (magnum)
* New option: --log-stderr (magnum)
* New option: --regenerate-lost-salts=N for cracking hashes where we do not
have the salt and essentially need to crack it as well (JimF)
* New unlisted option: --list (for bash completion, GUI, etc.) (magnum)
* --list=[encodings|opencl-devices] (magnum)
* --list=cuda-devices (Lukas)
* --list=format-details (Frank)
* --list=subformats (magnum)
* New unlisted option: --length=N for reducing maximum plaintext length of a
format, mostly for testing purposes (magnum)
* Enhanced parameter syntax for --markov: may refer to a configuration file
section, may specify the start and/or end in percent of total (Frank)
* Make incremental mode restore ETA figures (JimF)
* In "dynamic", support NUL octets in constants (JimF)
* In "salted-sha1" (SSHA), support any salt length (magnum)
* Use comment and home directory fields from PWDUMP-style input (magnum)
* Sort the format names list in "john" usage output alphabetically (magnum)
* New john.conf options subsection "MPI" (magnum)
* New john.conf config item CrackStatus under Options:Jumbo (magnum)
* \xNN escape sequence to specify arbitrary characters in rules (JimF)
* New rule command _N to reject a word unless it is of length N (JimF)
* Extra wordlist rule sections: Extra, Single-Extra, Jumbo (magnum)
* Enhanced "Double" external mode sample (JimF)
* Source $JOHN/john.local.conf by default (magnum)
* bash completion for JtR (to install: "sudo make bash-completion") (Frank)
* benchmark-unify: a Perl script to unify benchmark output of different
versions of JtR for use with relbench (Frank)
* Per-benchmark speed ratio output added to relbench (Frank)
* New program: raw2dyna (helper to convert raw hashes to "dynamic") (JimF)
* New program: pass_gen.pl (generates hashes from plaintexts) (JimF, magnum)
* linux-*-native make targets (pass -march=native to gcc) (magnum)
