7-Zip security overview
At least from version 3.x, 7-Zip has been using a strong AES algorithm, which doesn't allow any attacks more effective
than the brute force. Besides, the key derivation function is very similar to RAR one, and uses more than 130000 SHA-256 transformations and brute force rate on modern CPU is very low,
only several hundreds of passwords per second. This carries inference that 7-Zip password encryption is one of the strongest between popular encryption systems in the context of brute force rate.
