TheEcdsaParams dictionary of theWeb Crypto API represents the object that should be passed as thealgorithm parameter intoSubtleCrypto.sign() orSubtleCrypto.verify() when using theECDSA algorithm.

Instance properties

name

A string. This should be set toECDSA.

hash

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

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

Warning:SHA-1 is also supported here but theSHA-1 algorithm is considered vulnerable and should no longer be used.

Examples

See the examples forSubtleCrypto.sign() orSubtleCrypto.verify().

Specifications

Browser compatibility

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