Which OSI model layer handles encryption?

The Presentation Layer is the sixth layer of the OSI (Open Systems Interconnection) model. Its primary role is to ensure that data is presented in a format that the receiving system can understand. It performs functions such as encryption, decryption, data compression, and data format translation (e.g., converting between different character encoding formats). By encrypting data before transmission and decrypting it upon reception, the Presentation Layer helps maintain data confidentiality and secure communication between networked systems.
