+backup_compression_format = tar
+backup_compression = gzip
+encryption = gpg
+encryption_key_id = barman <-- the name you gave previous
+encryption_passphrase_command = "cat /etc/barman.d/secret"
+</code>
+**Done**
+You will have to re-initiate the backup, ie (be careful and not just c&p, but think, you can loose the existing backup):
+<code>
+sudo barman cron
+sudo -u barman  barman receive-wal --create-slot SERVER-NAME
+sudo -u barman  barman switch-xlog SERVER-NAME
+sudo -u barman  barman backup SERVER-NAME
+</code>
+If create-slot fails, you will have to --drop-slot or drop the slot from the database.
+You can check if the encryption is on:
+<code>
+sudo -u barman  barman check SERVER-NAME | grep encryption
+# This should do it
+#
+# but you can also see it:
+# and in your barman-backup-dir/SERVER-NAME/base/BACKUP-SET/ will have a basebackup ending on .gpg
+# and in your barman-backup-dir/SERVER-NAME/wals/WAL-SET/ the wal file will respond to
+# file wal-file
+# wal-file: PGP RSA encrypted session key - keyid: 43F52AD6 99DF306B RSA (Encrypt or Sign) 3072b
+</code>
+===== Warnings =====
+If you - like us - have a monitor system that counts the numbers of "OK" from the output
+<code>
+sudo -u barman  barman check SERVER-NAME
+</code>
+It will fail because there are now 23 OK's (hopefully) and not the 22 OK's :-)
