EcKeyGenParams

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.

Instance properties

name

A string. This should be set to ECDSA or ECDH, 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 for NIST-approved curves:

• P-256
• P-384
• P-521

Examples

See the examples for SubtleCrypto.generateKey().

Specifications

Browser compatibility

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