A method includes receiving a request to execute bytecode that corresponds to secured program code, the secured program code including an encrypted version of the bytecode. Based on receiving the request to execute the bytecode, the method resolves the request, the resolving including identifying a location on disk of the secured program code. Based on resolving the request, a license file for decrypting the encrypted version of the bytecode for execution is accessed, the license file including an encrypted key-value. The encrypted key-value is used in decrypting the encrypted version of the bytecode to obtain decrypted bytecode, where the decrypting places the decrypted bytecode in working memory, and the decrypted bytecode is executed.

Code protection

An update is deployed to a guest virtual machine of a hypervisor during runtime of the guest virtual machine. An executing thread of the guest virtual machine is identified and execution of the thread is redirected to a function to open a handle to a file, of the guest virtual machine, to which data of the update is to be written. The data is provided to a component of the guest virtual machine, and then execution of the thread is redirected to a function to write the data provided to the component to the file.
