![]() ![]() For increasing the cost of exhaustive search for passwords 7-Zip uses big number of iterations to produce cipher key from text password.įor me, I've always regarded 7zip as the better choice for compression tool (i've tested it myself) Furthermore, its FREE. A key derivation function produces a derived key from text password defined by user. ![]() To create that key 7-Zip uses derivation function based on SHA-256 hash algorithm. This algorithm uses cipher key with length of 256 bits. Is there anything that WinZip can do that 7ZIP can't?ħ-Zip also supports encryption with AES-256 algorithm. I want to replace the outdated software with 7ZIP to save cost - which is capable of AES-256 encryption - but the user has his doubts about it. He's worried that the customer won't be able to open the files (a standard, password-protected file archive in a. One of our uses has an out of support version of WinZip, which he uses to send files to a customer. ![]()
