I think there's a general consensus that the minimum recommended key size for X9.42 Diffie-Hellman PGP keys is 1024bits. I'm not sure if the standard size is 1536bits. I might be wrong, but I don't believe such a key length standard exists. I think the only size related limitation in X9.42 was related only to size of the prime defining the Galos Field. I haven't worked with X9.42 before. There does not appear to be many 1536bit keys in the global PGP public keyring (the keys of the synchronized public keyservers). I count 1,057 in my copy of the ring, or 0.0748% of the total keys in the ring. Here is more information about that ring: http://gnv.us.ks.cryptnet.net/stats.html Notice the % of keys which is =< 1024bits. - VAB --- V.
