Advanced Archive Password Recovery Professional (ARCHPR) v4.50

Advanced Archive Password Recovery (ARCHPR) recovers protection passwords or unlocks encrypted ZIP and RAR archives created with all versions of popular archivers. Recover passwords for plain and self-extracting archives created with PKZip and WinZip, RAR and WinRAR automatically or with your assistance. Guaranteed unlocking of archives created with WinZip 8.0 and earlier in under one hour is possible by exploiting an implementation flaw.

       

ARCHPR features ultimate compatibility among the various types of archives, knows weaknesses of certain types of protection, and provides best-in-class performance in unlocking all types of archives.

Features and Benefits

•	Supports all versions of ZIP/PKZip/WinZip, RAR/WinRAR, as well as ARJ/WinARJ, and ACE/WinACE (1.x)

•	Guaranteed recovery of archives in under 1 hour for ZIP archives created with WinZip 8.0 and earlier and containing at least 5 files

•	Supports archives over 4 GB and self-extracting archives

•	Supports strong AES encryption found in WinRAR and the new versions of WinZip

•	Exploits all known vulnerabilities and implementation flaws in the various compression algorithms for faster recovery

•	Speedy known-plaintext attack recovers certain ZIP and ARJ archives in minutes (user must supply at least one unprotected file from that archive)

•	Interrupt and resume operation at any time

•	Supports background operation by utilizing idle CPU cycles only

•	Dictionary and brute-force attacks with user-defined masks and advanced templates

•	Highly optimized low-level code for optimum performance

Please note, however, that for the password is not stored anywhere in the archive (ZIP/RAR/ARJ/ACE file), and so it cannot be just extracted or decrypted. Instead, ARCHPR can recover it by trying different passwords: all possible combinations in a given range, or from a wordlist, etc. ARCHPR can test as many as ten to thirty million passwords per second (for ZIP archives), and so the likelihood of finding a valid one is very high. There is still no guarantee that the password will be recovered, but here the human factor plays its role: most people use short and/or easy to remember passwords. We estimate the success rate as 90-95%.
