function

crypto.decapsulate

ciphertext: ArrayBufferLike | ArrayBufferView<ArrayBufferLike>

): NonSharedBuffer;

Key decapsulation using a KEM algorithm with a private key.

Supported key types and their KEM algorithms are:

'rsa' RSA Secret Value Encapsulation
'ec' DHKEM(P-256, HKDF-SHA256), DHKEM(P-384, HKDF-SHA256), DHKEM(P-521, HKDF-SHA256)
'x25519' DHKEM(X25519, HKDF-SHA256)
'x448' DHKEM(X448, HKDF-SHA512)
'ml-kem-512' ML-KEM
'ml-kem-768' ML-KEM
'ml-kem-1024' ML-KEM

If key is not a KeyObject, this function behaves as if key had been passed to crypto.createPrivateKey().

If the callback function is provided this function uses libuv's threadpool.
