Hi all, I try to perform an XML encryption of data by a secret key. In the w3c recommendations it is precised that the initialisation vector IV must be transmit but does not specified where : "the IV, if any, could be specified as being with the cipher data, as an algorithm content element, or elsewhere"
So with XmlSec I place the IV at the beginning of the ciphered data but how can I be sure that an other program will use it. Symmetrically, during decryption I take the IV at the beginning of the ciphered data. But how can I find it if the enrcypting program placed it elsewhere.
