Astrotite is a tool that packs, compresses and encrypts files securely within a single file, which will always be equal (same hash), while they are the same files that are compressed.
Astrotite also lets you hide files with password, making them undetectable and inextract without the correct password.
If you want to repair or share your Astrotite file with another, you just use the anonymous network AstroA2P to download or repare it. (if someone has uploaded to the system the same file)
I use the program for compress and decompress everything, it's very fast!.The program decompress .RAR, .ZIP, .TAR, .GZ and .BZ2 cool. Right click and "decompress here"
