: It encrypts a block of data using AES in Counter (CTR) mode.

: It supports "Associated Data"—information that needs to be authenticated but not encrypted (like IP headers). Common Use Cases High-Speed Networking

: By offloading these calculations from a general-purpose CPU to the EXPN64V2GCM engine, systems can achieve gigabit-per-second throughput with minimal latency. How EXPN64V2GCM Works

The is a high-performance cryptographic engine designed to accelerate GCM (Galois/Counter Mode) encryption and decryption tasks, typically within network security processors or FPGA-based hardware accelerators. What is EXPN64V2GCM?
