What is jarsigner?

The jarsigner tool fulfills two primary roles: it authenticates signatures and checks the integrity of signed JAR files, while also allowing users to sign Java Archive (JAR) files. A digital signature is a sequence of bits that originates from the data being signed and is combined with the private key of a particular signer, which could be a person or an organization, among others. Similar to a traditional handwritten signature, a digital signature offers several advantageous attributes; its validity can be verified through a calculation that utilizes the public key associated with the private key that created the signature. In addition, it is closely linked to the data that is signed, meaning that it cannot accurately represent a signature for any different data, and any modifications to the signed data result in the signature being deemed invalid. This system guarantees that it cannot be forged, as long as the private key is kept secure, thereby significantly boosting security in digital communications and transactions. Overall, the jarsigner utility is essential for maintaining trust and ensuring the authenticity of Java applications.

What is Keyfactor Signum?

Keyfactor Signum is designed to protect sensitive keys, automate policy enforcement, and seamlessly integrate signing operations with your current tools and build workflows. This solution enables the creation and secure storage of private signing keys within a centralized, cloud-hosted hardware security module (HSM) that is FIPS 140-2 certified. Users can implement intricate access and usage policies for these private keys and authenticate both users and build servers involved in the signing process, all while maintaining a thorough audit trail. By working alongside platform-native signing tools, it ensures the security of private signing keys without interfering with existing workflows. It also supports integration with signing tools via lightweight agents that are compatible with both Windows and Linux, allowing for swift deployment on build servers or developer workstations. Additionally, Keyfactor Signum provides key attestation to comply with CA/B forum standards, ensuring that keys are generated and stored within an HSM, which bolsters security and compliance efforts. This comprehensive system not only optimizes the signing workflow but also significantly mitigates the risk of key compromise, thereby enhancing overall security posture. Overall, Keyfactor Signum offers a robust solution that aligns with modern security needs and operational efficiency.
