[OT] Sed issue

[Dan Track]

Hi

I'm hoping one of you experts out there can help me. I'd like to
delete a file signiture from the top and bottom of a file. I know I
need to use sed, but my sed isn't that good. Could someone please help
me write a sed command. I would appreciate any help.

At the top of the file I have:

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
NotDashEscaped: You need GnuPG to verify this message


And at the bottom I have
-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.5 (GNU/Linux)

-----END PGP SIGNATURE-----

Thanks in advance
Dan
