Project Description

John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. On top of this, lots of other hashes and ciphers are added in the community-enhanced version (-jumbo), and some are added in John the Ripper Pro.

1.7.8-jumbo-4

Support for compile-time plugins has been introduced to make it easy to create non-conflicting source code patches adding new hash and cipher types. Performance at MSCash2 (Domain Cached Credentials of modern Windows systems) has been improved through the use of SSE2. "Generic MD5" code has been enhanced to provide more of the MD5 and SHA-1 based hash types under more build targets. WinZip/AES cracker has been enhanced with optional OpenMP parallelization.

1.7.8-jumbo-2

The jumbo patch has been rebased to 1.7.8. Support for cracking password-protected WinZip archives with AES encryption has been added. Compile-time detection of OpenSSL 0.9.8+ has been added, automatically enabling support for Sybase ASE and hmailserver hashes. The performance on MSCash2 (Domain Cached Credentials of modern Windows systems) has been improved. Other minor performance and portability improvements have been made.

1.7.8

The bitslice DES S-box expressions and code have been replaced, reducing the gate count by 17% and typically speeding up DES-based crypt(3) cracking by 13%. Support for bcrypt hashes of passwords containing non-ASCII characters has been corrected, and a backwards compatibility feature for broken bcrypt hashes of such passwords has been added. The external mode virtual machine's performance has been improved through additional multi-op instructions. AppendLuhn external mode has been added, which appends the Luhn algorithm digit. A few minor bugfixes and enhancements were made.

1.7.7-jumbo-6

Support for cracking OpenSSH's passphrase-protected SSH protocol 2 private keys (with OpenMP parallelization), password-protected PDF files with RC4 encryption, and some password-protected RAR archives has been added. Support for SybaseASE, hmailserver, and MediaWiki "B" type password hashes has been added. There were also many minor enhancements.

1.7.7-jumbo-5

MD5 and SHA-1 based hashes have been sped up with SSE2 intrinsics. md5_gen has been expanded with more hash types. UTF-8 support has been added ("--utf8"). MPI parallelization support for all cracking modes has been integrated. OpenMP parallelization support has been added to more hash types. New formats have been added: mskrb5 (offline attack on MS Kerberos 5 pre-authentication data), rawMD5unicode (MD5 of UCS-2 encoded plaintext), and salted_sha1 (faster handling of some LDAP {SSHA} hashes). The "unique" program, Markov mode, ETA display, and programming interfaces have been enhanced.
