Implement on-chain encryption using vetKeys (verifiable encrypted threshold key derivation). Covers key derivation, IBE encryption/decryption, transport keys, and access control. Use when adding encryption, decryption, on-chain privacy, vetKeys, or identity-based encryption to a canister. Do NOT use for authentication — use internet-identity instead.

Note: vetKeys is a newer feature of the IC. The ic-vetkeys Rust crate and @dfinity/vetkeys npm package are published, but the APIs may still change over time. Pin your dependency versions and check the DFINITY forum for any migration guides after upgrades.
vetKeys (verifiably encrypted threshold keys) bring on-chain privacy to the IC via the vetKD protocol: secure, on-demand key derivation so that a public blockchain can hold and work with secret data. Keys are verifiable (users can check correctness and lack of tampering), encrypted (derived keys are encrypted under a user-supplied transport key—no node or canister ever sees the raw key), and threshold (a quorum of...
