Pbkdf2Params
Pbkdf2Params:
object
The Pbkdf2Params dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into SubtleCrypto.deriveKey, when using the PBKDF2 algorithm.
Type declaration
hash
hash:
string| {name:string; }
A string or an object containing a single property called name with a string value. It is an identifier for the digest algorithm to use. This should be one of the following:
SHA-256: selects the SHA-256 algorithm.SHA-384: selects the SHA-384 algorithm.SHA-512: selects the SHA-512 algorithm.
iterations
iterations:
number
A Number representing the number of times the hash function will be executed
in deriveKey(). This determines how computationally expensive (that is, slow)
the deriveKey() operation will be. In this context, slow is good, since it
makes it more expensive for an attacker to run a dictionary attack against
the keys. The general guidance here is to use as many iterations as possible,
subject to keeping an acceptable level of performance for your application.
name
name:
string
A string. This should be set to PBKDF2.
salt
salt:
BufferSource
An ArrayBuffer, a TypedArray, or a DataView. This
should be a random or pseudo-random value of at least 16 bytes. Unlike the
input key material passed into deriveKey(), salt does not need to be kept secret.
