Export the Public Key Certificate
You now have a signed JAR file
sCount.jar. The runtime system of the code receiver (Ray) will need to authenticate the signature when the
Count application in the signed JAR file tries to read a file and a policy file grants that permission to this signed code.
In order for the runtime system to authenticate the signature, Ray's keystore needs to have the public key corresponding to the private key used to generate the signature. You supply this by sending Ray a copy of the certificate authenticating the public key. Copy that certificate from the keystore
examplestore to a file named
Example.cer via the following:
keytool -export -keystore examplestore -alias signFiles -file Example.cer
You will be prompted for the store password.
