xml.Encryption.setKeyEncryptionKey

Assigns a copy of the key-encryption key to this Encryption object.

Syntax

setKeyEncryptionKey(
   key xml.CryptoKey )

key is the key-encryption key.

Usage

Any further XML encryption will use that key-encryption key to encrypt the symmetric key set with setKey() within the resulting XML, and any further XML decryption will use that key-encryption key to decrypt the embedded symmetric key.

NULL is allowed, meaning that embedded symmetric keys will not be encrypted nor decrypted anymore, assuming that they have been exchanged in another way.
Only public or private RSA keys, or key-wrap keys are allowed.
Public RSA keys can encrypt but not decrypt.

In case of error, the method throws an exception and sets the STATUS variable with the appropriate error number.
