My keys

Secure communication across the Internet requires cryptography.
This page documents the keys I use.
For email I use PGP/GPG - I have never seen the point of S/MIME.
For remote logon I use ssh (I refuse to use telnet/rlogin).

Before using these keys be sure to verify them by some other means than this page (call me, email me or check the signatures on my pgp key and if you find someone you know, then use gpg/pgp to verify the signatures of my ssh keys).


My public key is:
pub   4096R/27C0BBB2 2014-05-31
uid                  Flemming Jacobsen <>
uid                  Flemming Jakobsen <>
sub   4096R/0C909699 2014-05-31

Fingerprint: 7689 629A 5BD8 5065 05EC  6CB1 4EC7 0DA5 27C0 BBB2
It can be found here.
You can also get the latest version with new signatures on it at or at - the later server produce more readable output but is less wellknown.

The PGP pathfinder is a great way to find trustpaths between arbitrary keys.
You can use it to find paths between your key and mine:

your key id :

PGP key signing policy:

When I sign a key, it does not convey any kind of opinion on the trustworthiness of the owner.

In general I will sign a key if:

If the name on your key (to me) is clearly an alias, then I probably will sign your key even without an ID.


The key I use on my private computers is here (Signature).
