AWS Key Management Service (KMS) now supports the Edwards-curve Digital Signature Algorithm (EdDSA), specifically the Edwards25519 curve (Ed25519).
</p>
<ul>
<li>Provides 128-bit security level equivalent to NIST P-256</li>
<li>Offers faster signing performance</li>
<li>Features small signature size (64 bytes) and public key size (32 bytes)</li>
<li>Ideal for IoT devices and blockchain applications</li>
<li>Available in all AWS Regions, including GovCloud and China Regions</li>
</ul>
<p>
This new capability allows users to create elliptic curve asymmetric KMS key or data key pairs for signing and verifying EdDSA signatures.
