support for recovering ZIP (archive) passwords

[philsmd]

This feature request was originally reported on the (now obsolete and offline) trac ticketing system of hashcat.net.

Ticket details:
Original reporter (OP):	minga
Title:	OCL support for .ZIP files
Ticket number:	161
Date reported:	2013-06-14T18:25:06+02:00
Description:	Auditors/Forensics people need to crack ZIP files. Would [be awesome to be able to] just [to] use OCL for this.

---

Comments:
1.	Rolf	ZipClassic (96 bit custom encryption used in the Old Days) should be supported too. It's not very GPU friendly, but the speeds are good (800M+ on GTX Titan using Passcovery).

---

Note: this ticket is not about .7z; recoverying passwords of .7z archives is already supported (-m 11600 = 7-Zip). The feature to add support for recovering RAR passwords was mentioned within a separate issue #68 (therefore please discuss here only about the different types of .zip files).

Note we've added WinZip support, PKZIP is still missing

Any update?

[BTCBOY]

PKzip support would be really helpful

[philsmd]

added with:

1. Added pkzip kernels 17200, 17210, 17220 and 17230 #1962 (-m 17200 = compressed, -m 17210 = uncompressed, -m 17220 = compressed multiple files, -m 17230 = as 17220 but only checksum check)
2. Adding pkzip stream cipher kernels 20500 and 20510 #2032 (-m 20500 = Master Key "hash" for password recovery (forensic purpose if password needs to be known, not only the key) by exploiting a known plaintext attack (KPA), e.g. using bkcrack, -m 20510 = Master Key "hash" for password recovery, 20500 optimized to brute-force the first 6 bytes (prepended) )
