Verifying artifact signature on Remote Engines

Talend Studio signs Jobs before they are deployed to Talend Management Console using Java Jar signing (Signed JAR File). You can enable Remote Engines for Job signature verification.

You can use a default signing key bundled with Talend Studio or your custom signing key for this verification.

The META-INF folder of the zip file contains a .SF file with the SHA-256 digests of every file contained in the zip, as well as the digest of the manifest itself. The signing key itself is bundled with Talend Studio. This signs the .SF file and outputs the signature into a .RSA file in META-INF. The signature algorithm used is RSA-SHA256.
