AES-256-GCM

The gold standard for authenticated encryption, combining 256-bit brute-force resistance with hardware-accelerated integrity checks.

AES-256-GCM is the industry workhorse for securing data in transit (TLS 1.3) and at rest. It utilizes a 256-bit key length to satisfy Top Secret security requirements while employing Galois/Counter Mode to provide simultaneous encryption and authentication. This dual-purpose design prevents bit-flipping attacks without the overhead of separate HMAC passes. On modern CPUs, Intel AES-NI instructions offload the math to dedicated hardware, allowing throughput speeds exceeding 3 GB/s per core. It is the precise choice for high-performance systems where data privacy and message integrity are non-negotiable.
