crypto.webcrypto.SubtleCrypto.encapsulateKey

encapsulationAlgorithm: AlgorithmIdentifier,

encapsulationKey: CryptoKey,

sharedKeyAlgorithm: AlgorithmIdentifier | HmacImportParams | AesDerivedKeyParams | KmacImportParams,

extractable: boolean,

Uses a message recipient's asymmetric public key to encrypt a temporary symmetric key. This encrypted key is the "encapsulated key" represented as EncapsulatedKey.

The algorithms currently supported include:

'ML-KEM-512'
'ML-KEM-768'
'ML-KEM-1024'

@param usages

See Key usages.

@returns

Fulfills with EncapsulatedKey upon success.
