Methods

decrypt

decrypt(privateKey): Promise<ArrayBuffer>
Return the plaintext for the ciphertext contained in the current EnvelopedData value.
Parameters
- privateKey: CryptoKey
  The private key to decrypt the ciphertext.
Returns Promise<ArrayBuffer>
- Defined in src/lib/crypto/cms/envelopedData.ts:107

`Abstract` getRecipientKeyId

getRecipientKeyId(): Buffer
Return the id of the recipient's key used to encrypt the content.

This id will often be the recipient's certificate's serial number, in which case the issuer will be ignored: This method is meant to be used by the recipient so it can look up the corresponding private key to decrypt the content. We could certainly extract the issuer to verify it matches the expected one, but if the id doesn't match any key decryption won't even be attempted, so there's really no risk from ignoring the issuer.

Returns Buffer
- Defined in src/lib/crypto/cms/envelopedData.ts:128

serialize

serialize(): ArrayBuffer
Return the DER serialization of the current EnvelopedData value.

It'll be wrapped around a ContentInfo value.

Returns ArrayBuffer
- Defined in src/lib/crypto/cms/envelopedData.ts:94

`Static` deserialize

deserialize(envelopedDataSerialized): EnvelopedData
Deserialize an EnvelopedData value into a SessionlessEnvelopedData or SessionEnvelopedData instance.

Depending on the type of RecipientInfo.
Parameters
- envelopedDataSerialized: ArrayBuffer
Returns EnvelopedData
- Defined in src/lib/crypto/cms/envelopedData.ts:48
