In the OpenPGP context, probably the most interesting bit is that
the
160-bit hash limit has been removed. The sizes supported are:
* 1024-bit key, 160-bit hash (the current DSA)
* 2048-bit key, 224-bit hash (presumably aimed at SHA-224)
* 2048-bit key, 256-bit hash (presumably aimed at SHA-256)
* 3072-bit key, 256-bit hash (presumably aimed at SHA-256)
It also adds the concept of using a larger hash than will fit by
taking the leftmost bits.

the draft also refers to a previous draft of August/2005 (SP 800-
57)
which publishes a table of comparable strengths:

Part1.pdf
p.63
note that 3-DES is now referred to as TDEA
should this perhaps be included in rfc 2440 when 3-DES is
mentioned?
i.e.
when 3-DES is first mentioned,
it should be referred to as 3-DES(also known as TDEA)
