Keys
This section describes the elliptic curves and key specifications which are currently supported by the API. Supported curves and key specs are defined with a
type of either or symmetric or asymmetric. Certain symmetric keys support key derivation (i.e., such as the ChaCha20 stream cipher). Other key specs, such as RSA, are provided for convenience and to achieve table-stakes feature-parity with industry-standard key management solutions such as AWS Key Management Service, Azure Key Vault, Hashicorp Vault, etc.Key Spec | Description |
AES-256-GCM | default encryption for the master key of each Vault instance |
ChaCha20 | stream cipher useful with double-ratchet messaging algorithm |
RSA | 2048, 3072 and 4096-bit
RSASSA-PSS and RSASSA-PKCS1-V1_5-SIGN for sign/verify operations;
RSAES_OAEP_SHA_256 for encrypt/decrypt operations |
Key Spec | Description |
babyJubJub | a twisted Edwards elliptic curve designed for zk-SNARK circuits |
BIP39 | BIP39 hierarchical deterministic (HD) wallet for deriving secp256k1 keys |
C25519 | elliptic curve designed for Diffie-Hellman (ECDH) key exchange |
Ed25519 | EdDSA signature scheme using SHA-512 (SHA-2) |
RSA | 2048, 3072 and 4096-bit
PSS and PKCS for sign/verify operations
OAEPSHA256 for encrypt/decrypt operations |
secp256k1 | elliptic curve used with ECDSA (i.e., ETH, BTC) |
