How to use lexicon DNS API

lexicon is a python tool for a number of dns providers.

As I'm writing this doc, it supports the following dns api: The current supported providers are:

• Cloudflare
• DigitalOcean
• DNSimple
• DnsMadeEasy
• DNSPark
• EasyDNS
• Namesilo
• NS1
• PointHQ
• Rage4
• TransIP
• Vultr

You can check its project page: https://github.com/AnalogJ/lexicon

You must install python and lexicon before using it.

For more examples, please check lexicon page: https://github.com/AnalogJ/lexicon

Examples:

1. Using lexicon cloudflare api:

export PROVIDER=cloudflare
export LEXICON_CLOUDFLARE_USERNAME="xxxx@xxx.com"
export LEXICON_CLOUDFLARE_TOKEN="XXXXXXXXXXXXXXX"

acme.sh --issue  -d test.acme.sh  --dns  dns_lexicon

2. Using lexicon namesilo api:

Namesilo applies any submitted changes to DNS records every 15 minutes. To make sure verification aligns with propagation, --dnssleep must be set for 16 minutes (960 seconds). You may generate a new API key (namesilo-api-token) at the api manager under Account Options after logging in.

export PROVIDER=namesilo
export LEXICON_NAMESILO_TOKEN="namesilo-api-token"

acme.sh --issue  -d test.acme.sh  --dns dns_lexicon  --dnssleep 960

3. Using lexicon TransIP api:

export PROVIDER=TRANSIP
export LEXICON_TRANSIP_USERNAME="username"
export LEXICON_TRANSIP_API_KEY="/path/to/file.key"

acme.sh --issue  -d test.acme.sh  --dns  dns_lexicon

4. Using Technitium DNS via Lexicon ddns API:

In this example, we request a DNS-01-challenged ACME certificate using a custom (internal) ACME server via the Lexicon API via Technitium DNS. Note that we use --dnssleep 0 to skip the public DNS check (since this is for an internal DNS setup).

There are some prerequisites to setup TSIG within Technitium. In Technitium's Web UI:

• Create a TSIG Key via Settings>TSIG. Set <KeyName>, <Algorithm>, and optionally <SharedSecret> (if you don't set Shared Secret, Technitium will create one for you when you click "Save"). For example:
  • KeyName: lexicon
  • SharedSecret: 12345abcde (NOTE: this is just an example!)
  • Algorithm: HMAC-SHA256
• Enable Zone Transfer and Dynamic Updates at Zones > example.com > Options > Zone Options.
  • [Zone Transfer tab] Zone Transfer: Allow
  • [Zone Transfer tab] Zone Transfer TSIG Key Names: <KeyName> from above - optionally you can select your KeyName from "Quick Add" menu
  • [Dynamic Updates tab] Dynamic Updates: Allow (use "Specified IP Addresses" if possible)
  • [Dynamic Updates tab] Add a security policy with the following options:
    • TSIG Key Name: <KeyName>
    • Domain Name: *.example.com
    • Allowed Record Types: TXT

In your acme.sh CLI session:

export PROVIDER=ddns
# Format: export LEXICON_DDNS_DDNS_SERVER=<DNS Server IP>
export LEXICON_DDNS_DDNS_SERVER=10.1.0.5
# Format: export LEXICON_DDNS_TOKEN=<Algorithm>:<KeyName>:<SharedSecret>
export LEXICON_DDNS_TOKEN=hmac-sha256:lexicon:12345abcde

acme.sh --issue \
    -d test.example.com \
    --dns dns_lexicon \
    --server https://hcv.ff.lan/v1/pki_int/acme/directory \
    --dnssleep 0
