[Android]產生keystore

release:


$ keytool -genkey -v -keystore my-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000


debug:


$ keytool -genkey -v -keystore debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000


get release finger print:


$ keytool -list -v -keystore [keystore path] -alias [alias-name] -storepass [storepass] -keypass [keypass]



get debug finger print:

$ keytool -list -v -keystore debug.keystore -alias androiddebugkey -storepass android -keypass android
