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.
