Trail: Security in JDK 1.2
Lesson: Signing Code and Granting It Permissions

## Sign the JAR File

> Now you are ready to sign the JAR file. Type the following in your command window to sign the JAR file `Count.jar`, using the private key in the keystore entry aliased by `signFiles`, and to name the resulting signed JAR file `sCount.jar`:

> >     jarsigner -keystore susanstore -signedjar sCount.jar Count.jar signFiles

> You will be prompted for the store password (`ab987c`) and the private key password (`kpi135`).

> > Note: The `jarsigner` tool extracts the certificate from the keystore entry whose alias is `signFiles` and attaches it to the generated signature of the signed JAR file.
