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

Properties

name
A DOMString. This should be set to ECDSA.
hash
A DOMString. 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 SubtleCrypto.sign() or SubtleCrypto.verify().

Recommendation  

Browser compatibility

Browsers that support the "ECDSA" algorithm for the SubtleCrypto.sign() and SubtleCrypto.verify() methods will support this type.
