Classes

c
KeyStack(keys: Iterable<Key>)

A cryptographic key chain which allows signing of data to prevent tampering, but also allows for easy key rotation without needing to re-sign the data.

  • indexOf(
    data: Data,
    digest: string
    ): Promise<number>

    Given data and a digest, return the current index of the key in the keys passed the constructor that was used to generate the digest. If no key can be found, the method returns -1.

  • length(): number

    Number of keys

  • sign(data: Data): Promise<string>

    Take data and return a SHA256 HMAC digest that uses the current 0 index of the keys passed to the constructor. This digest is in the form of a URL safe base64 encoded string.

  • verify(
    data: Data,
    digest: string
    ): Promise<boolean>

    Given data and a digest, verify that one of the keys provided the constructor was used to generate the digest. Returns true if one of the keys was used, otherwise false.

Functions

f
timingSafeEqual(
a: ArrayBufferView | ArrayBufferLike | DataView,
b: ArrayBufferView | ArrayBufferLike | DataView
): boolean

When checking the values of cryptographic hashes are equal, default comparisons can be susceptible to timing based attacks, where attacker is able to find out information about the host system by repeatedly checking response times to equality comparisons of values.

Interfaces

I
StdCrypto

Extensions to the Web Crypto interface.

I
StdSubtleCrypto

Extensions to the web standard SubtleCrypto interface.

  • digest(
    algorithm: DigestAlgorithm,
    data:
    BufferSource
    | AsyncIterable<BufferSource>
    | Iterable<BufferSource>
    ): Promise<ArrayBuffer>

    Returns a new Promise object that will digest data using the specified AlgorithmIdentifier.

  • digestSync(
    algorithm: DigestAlgorithm,
    data: BufferSource | Iterable<BufferSource>
    ): ArrayBuffer

    Returns a ArrayBuffer with the result of digesting data using the specified AlgorithmIdentifier.
