# - DOMAIN
|

# The domain name (CN or subject alternative name) being

# validated.
|

|
|
# - TOKEN_FILENAME
|

|
# The name of the file containing the token to be served for HTTP

# validation. Should be served by your web server as

|
# - TOKEN_VALUE

# validation, this is what you want to put in the _acme-challenge
|

# TXT record. For HTTP validation it is the value that is expected
|

|
# be found in the $TOKEN_FILENAME file.

# Simple example: Use nsupdate with local named

|
# printf 'server 127.0.0.1\nupdate add _acme-challenge.%s 300 IN TXT "%s"\nsend\n' "${DOMAIN}" "${TOKEN_VALUE}" | nsupdate -k /var/run/named/session.key
