[Cryptography] Two quick questions about IPsec AH

[R Perlman]

1) Is anyone using it, or are they just using ESP?

2) The length field in AH is expressed in units of 4 bytes, and AH in
general was made to look like an IPv6 extension header, but IPv6 extension
headers have the length expressed in multiples of 8 bytes.  Is there an
interesting story there?

Thanks,
Radia
