[xmlsec] Questions about IV(Initial Vector)

[Aleksey Sanin]

Hi!

XML Encryption spec describes how the IV vector is used and XML Sec
library strictly follows the standards :)

http://www.w3.org/TR/xmlenc-core/#sec-Alg-Block:

The IV is encoded with and before the cipher text for the algorithms below
for ease of availability to the decryption code and to emphasize its
association
with the cipher text. Good cryptographic practice requires that a
different IV be
used for every encryption.


With best regards,

Aleksey.
