HmacImportParams
The HmacImportParams
dictionary of the Web Crypto 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 algorithm.
Instance properties
name
-
A string. This should be set to
HMAC
. hash
-
A string representing the name of the digest function to use. The can take a value of
SHA-256
,SHA-384
, orSHA-512
.Warning: Although you can technically pass
SHA-1
here, this is strongly discouraged as it is considered vulnerable. length
Optional-
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.

Browser compatibility
Browsers that support the "HMAC" algorithm for the SubtleCrypto.importKey()
, SubtleCrypto.unwrapKey()
methods will support this type.
