WinRAR Beta x64 - WinRARx64 is a trialware file archiver for Windows 64-bit processors. This utility software can combine files into one archive file or a series of archive files. To protect your files, WinRAR uses 128 Advanced Encryption Standard or AES. The program will not check your password. Instead, it will input a passcode through a hash function to encrypt your file’s contents. This feature prevents hackers from seeing archived files or accessing content that has been packed.
