PGP pathfinder & key statistics

• input : key id's of length 8, 16, 24, 32 or 40, optionally preceeded by 0x, in upper or lowercase, like

  FC243F3C      0xfc243f3c

• example : find trust paths from D5327CB9 (Wietse Venema) to FC243F3C (me)

• If you have a PGP page, visitors may want to find trust paths to your key ; here is what I use :

  your key id :

  To make this work for you, just include this piece of html :

    <FORM METHOD="GET" ACTION="http://pgp.cs.uu.nl/mk_path.cgi">
    your key id :
    <INPUT TYPE=TEXT    NAME=FROM   SIZE="10">
    <INPUT TYPE=HIDDEN  NAME=TO     VALUE="********">
    <INPUT TYPE=SUBMIT  NAME=PATHS  VALUE="find trust paths to me">
    <INPUT TYPE=RESET   NAME=reset  VALUE="reset">
    </FORM>

  and replace ******** with your key_id.
