ZipSigner is an Android utility for signing ZIP, APK, and JAR files directly on a phone. It suits developers, themers, and advanced Android users who need to prepare an update package or re-sign an edited archive without a desktop. Choose an input file, set the output location, select a built-in certificate or private-key keystore, and start the signing process. The app can also create keystores, keys, and self-signed certificates, then expose certificate fingerprints from key properties. Its compact workflow keeps file signing and verification tools close at hand.
