jarsigner Description

The jarsigner software has two functions: to verify the integrity and signatures of signed JAR files, and to sign Java Archive files (JAR). A digital signature is a sequence of bits that are computed using some data (the signed data) and the private keys of an entity (a company, person, etc.). A digital signature is similar to a handwritten one in that it has many useful features. Its authenticity can be verified using the public key of the private key used to create the signature. It is a function for the data signed, and cannot be claimed as the signature for any other data. The signed data cannot also be changed. If the data has been altered, the signature cannot be verified and it cannot be forged if the private key is kept confidential.
