Has it kept up with the known attacks? It predates a lot of work we did
in IETF on IPsec, for example. For example I had to axe the implicite
IV mode for DES-CBC due to the hamming distance attack. "But schnier
lists counters as a valid method of generating IVs....". Sheesh, there
is such a thing as new attacks (even if they are old to the NSA) as
being reasons NOT to site old texts.
