# Apk Sign

Automatically sign an apk with the Android test certificate. The public and private keys are embedded within the jar.

- `java -jar sign.jar my.apk` 

`my.s.apk` is created next to `my.apk`

- `java -jar sign.jar my.apk --override` 

`my.apk` is replaced with a signed version

Verify signature.

`jarsigner -verify my.s.apk`

### Changes

While the name `ApkSign` is similar to `apks`, no source from dex2jar is used in this project.
