2021.01 Release

Now that APKMirror is only serving decrypted files, this updates adds a check to see if there is any encryption in the first place!

Initial release

Fairly simple, use on a command line and give it a .apkm to decrypt!

Updates since 1.0:

• Now fixes the ZIP files that are decrypted to be proper ZIPs rather than broken ones.
• Build process targets to java 6 se, ensuring max compatibility
