HkdfParams
dictionary of the
Web 加密 API
represents the object that should be passed as the
algorithm
parameter into
SubtleCrypto.deriveKey()
, when using the
HKDF
算法。
名称
DOMString
. This should be set to
HKDF
.
hash
A
DOMString
表示
digest algorithm
to use. This may be one of:
SHA-1
SHA-256
SHA-384
SHA-512
salt
BufferSource
。
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.
info
BufferSource
representing 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
SubtleCrypto.deriveKey()
.

Browsers that support the "HKDF" algorithm for the
SubtleCrypto.deriveKey()
method will support this type.
