Elcomsoft Phone Breaker (formerly called Elcomsoft Phone Password Breaker) is an excellent mobile access cracking tool for the encrypted (password-protected) backups of iOS, Windows Phone, Windows Mobile and BlackBerry smartphone or other mobile devices, and a well-crafted mobile forensics tool for Windows and Mac that can be used by legal departments. It's developed by ElcomSoft from Russia.

If someone says you want to use this kind of tool to verify the security of passwords or recover them, that would be a joke, I think. After all, a rule for secure enough password is very simple - Uppercase + Lowercase + Number+ Symbol (and > 8 characters), there is no need of any tool to validate it at all. The same for wireless network password, restoring it is meaningless - just reset the router to default, which is the most efficient way. So, obviously they are designed for passwords cracking only.

For archived files (mainly RAR or ZIP format), that is very embarrassed and depressed in two cases. First, the archive file downloaded from the Internet prompts you need password to extract it out; Second, some important archive was protected using your own password, but you just forgot it. If so, turn to the Advanced Archive Password Recovery for help.
