Fully homomorphic encryption lets you compute on ciphertext without ever decrypting it. The promise is staggering and the slowdown is real. Here is the honest map of the schemes, the performance wall, and where FHE has actually shipped in 2026.

Post-Quantum Cryptography in 2026: Kyber, Dilithium, and the Migration That Already Started A practical, working-engineer's look at where post-quantum cryptography actually stands in mid-2026: what NIST shipped in FIPS 203/204/205, the Module-LWE math behind ML-KEM and ML-DSA at a level you can defend in a code review, the hybrid TLS and SSH deployments already moving real traffic, and the honest cost of the migration in bytes, milliseconds, and operational pain.
