Encrypting code and data at rest within an application protects sensitive components from static analysis. The encrypted portions are only decrypted during runtime and typically kept in memory for the shortest time possible.
This strategy can be helpful when dealing with confidential logic or licensing payloads, and helps prevent extraction of executable content, especially from unpacked binaries. But care needs to be taken so that code and data cannot be compromised at runtime.
iLok Licensing provides runtime encryption of application logic through its wrapper integration.
