Controlling the KVM switch via XML
The data block is formed as follows:
plain text padding
encrypt using
Initialization Vector (IV)
encrypted data
IV
BASE64
encoded data
Padding is required to make the data block to be encrypted multiple times larger than
block size (8 bytes). The XML API expects that the last byte of the padding states
the number of added padding bytes. The padding bytes are to be randomly selected.
The initialization vector is required for stream ciphers (here: CBC ). It is randomly
selected in the encryption mode Password encryption . Its size corresponds to the block
size of the selected encryption (8 bytes).
