src/sys/opencrypto: cryptosoft.c cryptosoft_xform.c
Log Message:
Change the way the IV is generated for AES-CTR: use a simple counter
instead of arc4random(). AES-CTR is sensitive against IV recurrence
(with the same key / nonce), and a random number doesn't give that
guarantee.
This needs a little API change in cryptosoft -- I've suggested it to
Open/FreeBSD, might change it depending on feedback.
Thanks to Steven Bellovin for hints.
