jarsigner
The jarsigner tool has two purposes, to verify the signatures and integrity of signed JAR files and to sign Java Archive (JAR) files. A digital signature is a string of bits that is computed from some data (the data being signed) and the private key of an entity (a person, company, and so on). Similar to a handwritten signature, a digital signature has many useful characteristics, its authenticity can be verified by a computation that uses the public key corresponding to the private key used to generate the signature, it is a function of the data signed and thus cannot be claimed to be the signature for other data as well, the signed data cannot be changed. If the data is changed, then the signature cannot be verified as authentic and It cannot be forged, assuming the private key is kept secret.
