Modifier and Type	Method	Description
byte[]	decrypt(PublicKey optionalPublicKey, CBORObject optionalKeyId, byte[] optionalEncryptedKey, PublicKey optionalEphemeralKey, KeyEncryptionAlgorithms keyEncryptionAlgorithm, ContentEncryptionAlgorithms contentEncryptionAlgorithm)	Decrypt encrypted key.

Method Details

decrypt

byte[] decrypt(PublicKey optionalPublicKey,
 CBORObject optionalKeyId,
 byte[] optionalEncryptedKey,
 PublicKey optionalEphemeralKey,
 KeyEncryptionAlgorithms keyEncryptionAlgorithm,
 ContentEncryptionAlgorithms contentEncryptionAlgorithm)

Decrypt encrypted key.

This interface assumes that the private key resides in an external hardware or software solution. The private key is either implicit or located by the optionalPublicKey or optionalKeyId parameters.

Implementations must throw CryptoException for errors related to cryptography and security.

Parameters:

optionalPublicKey - Defined it provided in the CEF object

optionalKeyId - Defined if provided in the CEF object

optionalEncryptedKey - Optional encrypted key (algorithm dependent)

optionalEphemeralKey - Optional ephemeral key (algorithm dependent)

keyEncryptionAlgorithm - The requested key encryption algorithm

contentEncryptionAlgorithm - The requested content encryption algorithm

Returns:

Decrypted key.
