ElcomSoft have done a good job on this program. From its roots as a command-based, underground program, it has developed into a product that could be used quite effectively in the corporate arena. The asking price of US$60 (for personal use) and US$120 (commercial license) is quite reasonable, considering the effort that goes into a program like this. In fact, US$120 is a bargain for many businesses.
My initial concerns about this program being used maliciously have been allayed by the fact that you need to have a pretty good estimate of the password to recover it in a short period of time. For example, an 8-character password, with uppercase, lowercase, special characters and numbers has over 6 quadrillion (6,000,000,000,000,000) possible combinations. My Pentium III was processing ZIP passwords at around 6 million/sec, at this rate the password would take approximately 32 years (maximum) to extract the password.
If you are using RAR files it's even harder - the password/sec rate plummets to fewer than 1,000 passwords per second. At this rate, the same combination would take a frightening (approx) 191,000 years!
I find it hard to believe that any "cracker" could take advantage of this program without having some idea as to the contents of the password. If a strong password is chosen (at least 8 characters, with uppercase, lowercase, numbers and special characters), and RAR format is used to compress files - then your archived data is almost totally secure from unwanted voyeurs (with the possible exception of government intelligence departments).
As this is my first software review, I was quite tentative on how to rate this product, but here's my verdict:
Quite affordable for businesses
Fast when recovering ZIP files
Easy to use
Many, many options to choose from
Could be used maliciously
Little pricey for personal users
Don't try to extract RAR archive passwords!
Rating - 8/10
