EcKeyGenParams

{{ APIRef("Web Crypto API") }} 

The EcKeyGenParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into {{domxref("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 {{domxref("SubtleCrypto.generateKey()")}} .

Browser compatibility

Browsers that support the “ECDH” or “ECDSA” algorithms for the {{domxref("SubtleCrypto.generateKey()")}}  method will support this type.
