Explanation
Encryption and decryption primarily occur at the Presentation layer (Layer 6) of the OSI model. This layer is responsible for translation, encryption, and compression of data to ensure it's in a format the application layer can use. Note: Some modern encryption also happens at the Application layer (SSL/TLS).
