AWS Key Management Service (KMS) announces support for the Edwards-curve Digital Signature Algorithm (EdDSA). With this new capability, you can create an elliptic curve asymmetric KMS key or data key pairs to sign and verify EdDSA signatures using the Edwards25519 curve (Ed25519). Ed25519 provides 128-bit security level equivalent to NIST P-256, faster signing performance, and small signature size (64 bytes) and public key sizes (32 bytes).
Ed25519 is ideal for situations that require small key and signature sizes, such as Internet of Things (IoT) devices and blockchain applications like cryptocurrency.
This new capability is available in all AWS Regions, including the AWS GovCloud (US) Regions and the China Regions. To learn more about this new capability, see Asymmetric key specs section in the AWS KMS Developer Guide.
