EcKeyGenParams

EcKeyGenParams: object

The EcKeyGenParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into SubtleCrypto.generateKey, when generating any elliptic-curve-based key pair: that is, when the algorithm is identified as either of ECDSA or ECDH.

Type declaration

name

name: "ECDSA" | "ECDH"

A string. This should be set to ECDSA or ECDH, depending on the algorithm you want to use.

namedCurve

namedCurve: string

A string representing the name of the elliptic curve to use. This may be any of the following names for NIST-approved curves:

• P-256
• P-384
• P-521
