Cipher Details
- AES-256-GCM — authenticated encryption with associated data (AEAD)
- PBKDF2 key derivation — 100,000 iterations, SHA-256, 256-bit output key
- Random 128-bit salt + 96-bit IV generated per operation via
crypto.getRandomValues - Output format: Base64(salt[16] || iv[12] || ciphertext) — fully self-contained
- All processing is client-side only — nothing ever leaves your browser
