Interfaces

Crypto

Provides basic cryptography features, such as a cryptographically strong random number generator, and access to cryptographic primitives via a SubtleCrypto object. An object of this type can be accessed in the global scope using Window.crypto or WorkerGlobalScope.crypto.

SubtleCrypto

Represents an object that provides low-level cryptographic functions for key generation, encryption, decryption, key wrapping and unwrapping, and so on.

CryptoKey

Represents a cryptographic key obtained from one of the SubtleCrypto methods generateKey(), deriveKey(), importKey(), or unwrapKey().
