encrypt
default byte[] encrypt(byte[] data, PublicKey publicKey) throws IOException, NoSuchAlgorithmException, InvalidKeyException, NoSuchPaddingException, InvalidAlgorithmParameterException Encrypts the givenInputStreamwith an AES session key calculated by KEM for the givenPublicKey. The returnedInputStreamhas the form [encapsulation length (big-endian, 2 bytes), encapsulation, AES initialization vector (12 bytes), AES encrypted data].- Parameters:
data- notnullpublicKey- notnull- Returns:
- byte array of [encapsulation length (big-endian, 2 bytes), encapsulation, iv (12 bytes), encrypted data]
- Throws:
IOExceptionNoSuchAlgorithmExceptionInvalidKeyExceptionNoSuchPaddingExceptionInvalidAlgorithmParameterException
