Usage
Unpacking
try (InputStream in = new FileInputStream("my_extension.crx") {
CrxMetadata metadata = CrxParser.getDefault().parseMetadata(in);
System.out.println("id = " + metadata.getId());
// handle remainder of stream as a zip archive
try (ZipInputStream zin = new ZipInputStream(in)) {
// ...
}
}
Packing
Path extensionDir = new File("manifest-parent-dir").toPath();
java.security.KeyPairGenerator keyGen = java.security.KeyPairGenerator.getInstance("RSA");
java.security.SecureRandom random = new java.security.SecureRandom();
keyGen.initialize(1024, random);
java.security.KeyPair keyPair = keyGen.generateKeyPair();
try (OutputStream out = new FileOutputStream("new_extension.crx")) {
CrxPacker.getDefault().packExtension(extensionDir, keyPair, out);
}
