HmacImportParams
dictionary of the
Web 加密 API
represents the object that should be passed as the
algorithm
parameter into
SubtleCrypto.importKey()
or
SubtleCrypto.unwrapKey()
, when generating a key for the
HMAC
算法。
名称
DOMString
. This should be set to
HMAC
.
hash
A
DOMString
representing the name of the
digest function
to use. The can take a value of
SHA-256
,
SHA-384
，或
SHA-512
.
警告
: Although you can technically pass
SHA-1
here, this is strongly discouraged as it is considered vulnerable.
length
可选
A
Number
representing the length in bits of the key. If this is omitted the length of the key is equal to the length of the digest generated by the digest function you have chosen. Unless you have a good reason to use a different length, omit this property and use the default.
See the examples for
SubtleCrypto.importKey()
.

SubtleCrypto.unwrapKey()
methods will support this type.
