public key block length ( seems very long )

public key block length ( seems very long )

Post by Anthony E. Cole » Wed, 16 Jul 2003 00:59:24



Hi,

Please forgive me if this is an ignorant question.  I just got my first set
of keys and I'm wondering why my public key is so long.  I see many users
with really short public keys.  Can someone help me understand why some
public keys are short and others are long?

Is there a way I can reduce the size of my public key?

Does my public key seem longer than normal?

Regards,

Anthony

Yes, you are correct.  I have been looking at the pgp signatures.

Thanks for the clarification!

Noone else attaches their public key top the message they
sign the message.  This results in a amount of data much
smaller than the public key look at Tom McCune's PGP FAQ

1. PUBLIC KEY BLOCK length

Hello !

As a beginner in trying PGP I've installed version 5.5.3i recently.
For test purposes I've made PGP creating several DH/DSS key pairs.
And now the thing I really don't understand at all:
Despite the fact I've chosen a key size of 3072/1024 (no matter with or
without "Fast key generation") the length of the PGP PUBLIC KEY BLOCK is
relatively short compared with those (DH/DSS key: e.g.2048/1024)
existing on the www-keyserver.
My PUBLIC KEY BLOCK (ASCII-text) fits in a normal sized Netscape Browser
window. In order to view other keys I have to scroll a lot to reach the
end...!!
Do freeware versions generate shorter keys by/at  the same bit size ??
Is there anything else that I can choose in order to get a long key ???
Please excuse the terrible english but I hope there is anybody who
understands what I wanna say.
However thanks for further information.

Sincerely,

Robin Sch?fer
