I've seen a few folks go doh when they go to encrypt their address or wonder if they have the vendor's old key or contact details. The script below runs in bash with everything you'd need to get encrypting and handling basic order details. One could go further and make it an order handling system given agora's cookie times but probably not worth the effort.

#!/bin/bash
# This is your GPG key ID for the optional encypted note portion below NOT the seller's key ID.
GPGID=
if [ ! -e address ]; then
echo " I need an address. I suggest block capitals, your country and
your ZIP+4 or other carrier codes relevant to your country. I will use this
address by default so be sure it is correct. remove or change the address file
to use another address. Press ctrl-d when done."
ADDRESS=$(</dev/stdin)
echo "$ADDRESS" > address
fi
read -p "Please provide seller name" SELLER
echo "Plesee provide seller key. Press ctrl-d when finished."
SKEY=$(</dev/stdin)
read -p "Please provide seller contact" SCONTACT
echo $SELLER
echo $SKEY
echo $SCONTACT
echo "$SKEY" >"$SELLER".key
gpg --import "$SELLER".key
echo "$SCONTACT" >> "$SELLER".key
mv "$SELLER".key "$SELLER".info
read -p "please enter key ID as provided above" SHORTFORM
gpg -e -r "$SHORTFORM" --armor address
# we backup the address encrypted here so that we can reuse it for the next order
mv address.asc address."$SELLER".asc
cat address."$SELLER".asc
# uncomment to allow notetaking and address history per order. requires existing gpg key to encrypt
# handy if you are using multiple drops, similar orders etc
# read -p "Please provide order ID" ORDERID
# echo "Please provide any additional notes relevant to this order. Press ctrl-d when finished."
# NOTES=$(</dev/stdin)
# echo "$NOTES" > $ORDERID
# echo "Address shipped to:" >> $ORDERID
# cat address >> $ORDERID
# gpg -e -r "$GPGID" $ORDERID
# rm -rf $ORDERID
edit: added more comments. yes you can copy and paste the vendor key when prompted. Be sure to ctrl-d after the paste.
This is kinda neat.
