Signed and Unsigned

Here are some quick scripts to sign every jar in a directory, and then unsign every jar.

Sign

find . -name "*.jar" -exec jarsigner -keystore /path/to/your/key -storepass yourpassword '{}' yourkeystorename \;

Unsign

find . -type f -iname '*.jar' -exec zip -d '{}' META-INF/*.{SF,RSA} \;
