🔒 What is AES-256-GCM Encryption?
AES-256-GCM is the gold standard for data encryption, adopted by the US Government, NSA, militaries, banks, and healthcare systems worldwide. The "256-bit" means there are 2²⁵⁶ possible keys — more than atoms in the observable universe. "GCM" mode adds cryptographic authentication, meaning your data cannot be read or secretly tampered with. VaultSends uses this with PBKDF2-SHA512 at 310,000 iterations, a unique 128-bit IV, and 256-bit salt per secret.
