+Hi,
 
-This message is sent as part of my certification process.
-It is to verify that you, the keyholder of $keyID can read email
-sent to the associated address
-$uid
+You are receiving this email because you gave me your OpenPGP key
+details for key-signing at $occasion.
 
-Please, now that you have decrypted this message, simply reply to
-  $myEmailAddress
-quoting
+This message is a challenge to help verify that you can read email sent
+to $uid and encrypted to the key with ID $keyID.
 
-> KeyID: $keyID
-> UserID: $uid
-> Magic: $challenge
-> Upload to keyserver after signing: yes
+You should have received an email for each UID, each containing a random
+string of data.  Please reply from each of the UIDs a message was sent
+to, including the random string, making sure you sign the message.  (You
+may encrypt your reply, but this is not necessary.)
 
-in the body of your message.
+After receiving your reply and checking that the challenge string
+matches the original, I will upload your key to a key server unless you
+specify otherwise.
 
-If you asked me to certify more than one userid or email address
-on your key you should receive one of these messages for each
-address - in that case please send one reply per address, too.
+My key-signing policy can be found at:
 
-After signing your key I will upload it to the keyserver network
-unless you oppose.

-Nachdem ich deinen Schlüssel signiert habe, werde ich ihn auf einen

-Hi!
-
-You are being sent this message because we exchanged OpenPGP key
-fingerprints at $occasion and you asked me to sign your
-key(s).
-
-Please decrypt the encrypted message for instructions on how to
-complete the certification protocol.
-
-If you don't know what I'm talking about, then please reply to me as
-soon as possible, since someone other than yourself tried to make me
-certify that the OpenPGP key with ID 0x$keyID does belong to you.
-In other words, someone tried to STEAL YOUR IDENTITY.

-Hallo!
-
-Wir haben in $occasion Fingerprints unserer OpenPGP-Schlüssel
-ausgetauscht, und du hast mich gebeten, deinen Schlüssel zu
-signieren.
-
-Die folgende verschlüsselte Nachricht erklärt, was du tun musst, damit
-ich deinen Schlüssel zertifiziere.
-
-Falls du nicht weißt, wovon ich rede, dann solltest du mich umgehend
-darüber informieren, da in diesem Fall jemand versucht deine E-Mail-
-Adresse als seine zu verkaufen.

-Viele Grüße
