TheEcKeyGenParams dictionary of theWeb Crypto API represents the object that should be passed as thealgorithm parameter intoSubtleCrypto.generateKey(), when generating any elliptic-curve-based key pair: that is, when the algorithm is identified as either ofECDSA orECDH.

Instance properties

name

A string. This should be set toECDSA orECDH, depending on the algorithm you want to use.

namedCurve

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

• P-256
• P-384
• P-521

Examples

See the examples forSubtleCrypto.generateKey().

Specifications

Browser compatibility

Browsers that support the "ECDH" or "ECDSA" algorithms for theSubtleCrypto.generateKey() method will support this type.
