EcdsaParams

{{ APIRef("Web Crypto API") }}

The EcdsaParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into {{domxref("SubtleCrypto.sign()")}} or {{domxref("SubtleCrypto.verify()")}} when using the ECDSA algorithm.

Instance properties

• name
  • : A string. This should be set to ECDSA.
• hash

  • : A string or an object containing a single property called name with a string value. It is an identifier for the digest algorithm to use. This should be one of the following:

    • SHA-256: selects the SHA-256 algorithm.
    • SHA-384: selects the SHA-384 algorithm.
    • SHA-512: selects the SHA-512 algorithm.

    [!WARNING] SHA-1 is also supported here but the SHA-1 algorithm is considered vulnerable and should no longer be used.

Examples

See the examples for {{domxref("SubtleCrypto.sign()")}} or {{domxref("SubtleCrypto.verify()")}}.
