The sdk only contains method for compression & decompression and its algorithm.
It also method for CRC, AES-256. But I can't find something related to password.
I came to know from a site that 7zip encrypt its file AES-256 & they say if you have password length>10 and if it also contain number, symbols and then
it is nearly impossible to crack with brute force unless quantum computers come.
I think I will not recover my file. I will never zip any file with password.
