AES-256
A symmetric encryption algorithm within the Advanced Encryption Standard (AES) with a key length of 256 bits. It is widely used to protect sensitive data and is regarded as having quantum resistance.
Timeline (last 90 days)
Grover's algorithm speeds up symmetric keys only quadratically, so a 256-bit key retains about 128 bits of security strength.
Data passing through machine learning endpoints must be encrypted end to end (TLS 1.3 in transit, AES-256 at rest), and enterprise agreements should guarantee that vendor models neither retain nor train on user data.
Grover's algorithm brings a quadratic speedup to symmetric key search, which can be effectively countered by doubling the key length, and AES-256 remains secure in the quantum era.
Without knowing the key, the time required to brute-force modern encryption algorithms such as AES-256 far exceeds the age of the universe.
GPUs such as the H100 with Hopper architecture integrate the memory encryption engine directly on-chip, performing AES-256 encryption at near-memory-bandwidth speeds, rather than simulating it through a software layer.
Bitwarden uses client-side AES-256 encryption before uploading.
The Suite B cryptographic suite used by the U.S. Department of Defense includes AES-256, ECDSA and ECDH, and SHA-384, while top-secret information uses the NSA's Type 1 encryption algorithm.
