HkdfParamsdictionary of the Web Crypto API represents the object that should be passed as the
SubtleCrypto.deriveKey(), when using the HKDF algorithm.
DOMString. This should be set to
BufferSource. The HKDF specification states that adding salt "adds significantly to the strength of HKDF". Ideally, the salt is a random or pseudo-random value with the same length as the output of the digest function. Unlike the input key material passed into
deriveKey(), salt does not need to be kept secret.
BufferSourcerepresenting application-specific contextual information. This is used to bind the derived key to an application or context, and enables you to derive different keys for different contexts while using the same input key material. It's important that this should be independent of the input key material itself. This property is required but may be an empty buffer.
See the examples for
|Web Cryptography API
The definition of 'SubtleCrypto.HkdfParams' in that specification.
Browsers that support the "HKDF" algorithm for the
SubtleCrypto.deriveKey() method will support this type.
