Title:
Java.III.CodePermissions
Download
Description: Code permissions in Java can be granted by 2 criterias- Location and Signer.
The resulting permission set is the union of all grants, which are applicable to a class.
Checks are performed only imperatively, in code, and new permissions can easily be added to the system.
An explanation of the example:
1. DemoPub.keystore contains the key of the demo publisher
2. The PermissionCheck class checks for AccessProfileInfoPermission and specific operation
3. The permission is granted based on location or signature
4. If jar file is not signed, the signature clause is not granted, and the check fails
5. Signing the jar enables passing checks for all operations
