PyEPP

A Python API on top of the EPP protocol and an EPP CLI client to work easier with registry systems.

This is a Python API on EPP protocol to connect to any registry systems that support EPP and work with it. Also, it is a CLI client to interact with the registry systems. It supports bellow RFCs:

• RFC 5730 - Extensible Provisioning Protocol
• RFC 5731 - Domain Name Mapping
• RFC 5732 - Host Mapping
• RFC 5733 - Contact Mapping
• RFC 5734 - Transport over TCP

Installation

pip install pyepp

Usage example

from datetime import date

from pyepp import EppCommunicator
from pyepp.domain import Domain, DomainData, DSRecordData, DNSSECAlgorithm, DigestTypeEnum
from pyepp.contact import Contact, ContactData, PostalInfoData, AddressData

# client_cert and client_key may be omitted where
# a registry does not require certificate based authentication
config = {
    "server": "epp.test.net.nz",
    "port": "700",
    "client_cert": "/PATH/TO/YOUR/CLIENT_CERTIFICATE.crt",
    "client_key": "/PATH/TO/YOUR/CLIENT_KEY.pem"
}

# Using the Pythonic context manager (recommended, handles connect, login, logout, and cleanup):
with EppCommunicator(**config, user="user_name", password="password") as epp:
    hello = epp.hello()
    contact = Contact(epp)
    contact_check = contact.check(['contact-1', 'contact-2'])

# Or using Configuration Profiles (AWS CLI style, loaded from ~/.pyepp/config.ini):
with EppCommunicator.from_profile("ote") as epp:
    contact = Contact(epp)
    contact_check = contact.check(['contact-1', 'contact-2'])

# Or using manual sequence management:
epp = EppCommunicator(**config)

connect = epp.connect()
login = epp.login("user_name", "password")
# Sends a hello request and receive greeting in respond
hello = epp.hello()

contact = Contact(epp)

# Check contacts availability
contact_check = contact.check(['contact-1', 'contact-2'])

# Create a new contact
contact_create_params = ContactData(
    id='contact-1',
    email='epp@example.net.nz',
    postal_info=PostalInfoData(
        name='Registrar 1',
        organization='Registrar 1',
        address=AddressData(
            street_1='18 Registrar Street',
            street_2='Registrar CBD',
            city='Registrar',
            country_code='NZ',
            province='Registrar',
            postal_code='6011'
        ),
    ),
    phone='+64.111111111'
)
contact_create = contact.create(contact_create_params)

# Get contact details
contact_info = contact.info('contact-1')

domain = Domain(epp)
# Check domains availability
domain_check = domain.check(['domain1.nz', 'domain2.nz'])

# Create a new domain name
domain_create_params = DomainData(
    domain_name='example.nz',
    registrant='contact-1',
    admin='contact-1',
    tech='contact-1',
    billing='contact-3',
    period=3,
    host=['01y.test-indwrx2vkicn2otgm3otav5wpnzvjd.co.nz', '0d9x6239.example.co.nz'],
    dns_sec=DSRecordData(
        key_tag=1235,
        algorithm=DNSSECAlgorithm.DSA_SHA_1.value,
        digest_type=DigestTypeEnum.SHA_1.value,
        digest='8cdb09364147aed879d12c68d615f98af5900b73'
    ),
)
domain_create = domain.create(domain_create_params)

# Renew a domain name
renew_domain = domain.renew(domain_name='example-1.nz', expiry_date=date(2024, 2, 23), period=2)

PyEPP CLI

PyEPP also has a command line interface that allows the user to interact with the registry system.

Usage: pyepp [OPTIONS] COMMAND [ARGS]...

  A command line interface to work with PyEpp library.

Options:
  -p, --profile TEXT              Configuration profile name from config.ini
                                  (e.g. ote, prod).
  -c, --config-file PATH          Explicit path to config.ini file.
  --server TEXT
  --port TEXT
  --user TEXT
  --password TEXT
  --client-cert TEXT
  --client-key TEXT
  --extension TEXT                The extension to be loaded for the EPP
                                  command.
  -o, --output-format [XML|OBJECT|MIN|TABLE]
                                  [default: XML]
  --no-pretty
  --dry-run
  -f, --file FILENAME             If provided, the output will be written in
                                  the file.
  -v, --verbose
  -d, --debug
  --version                       Show the version and exit.
  -h, --help                      Show this message and exit.

Commands:
  contact  To work with Contact objects in the registry.
  domain   To work with Domain name objects in the registry.
  hello    Sends a hello command to the server and receives the Greeting...
  host     To work with Host objects in the registry.
  poll     To manage registry service messages.
  profile  Manage and inspect EPP configuration profiles.
  run      Receive an XML file containing an EPP XML command and execute it.

Configuration Profiles (~/.pyepp/config.ini)

PyEPP supports user-defined configuration profiles (similar to AWS CLI profiles). Settings defined in [default] are shared globally and inherited by named profile sections ([profile <name>] or [<name>]):

[default]
port = 700
output_format = TABLE
no_pretty = false
dry_run = false

[profile ote]
server = epp.ote.registry.net.nz
user = test_registrar
password = secret_ote_pass
extensions = urn:ietf:params:xml:ns:secDNS-1.1

[profile prod]
server = epp.registry.net.nz
user = prod_registrar
password = secret_prod_pass
client_cert = ~/.pyepp/certs/client.crt
client_key = ~/.pyepp/certs/client.key
extensions = urn:ietf:params:xml:ns:secDNS-1.1

Using profiles with the CLI:

# List all configured profiles
pyepp profile list

# Show details of a profile (passwords masked by default)
pyepp profile show ote
pyepp profile show ote --show-secrets

# Run commands using a profile without needing --server, --user, or --password flags
pyepp -p ote domain check example.nz

Enable shell autocomplete

To enable shell autocompletion for your shell follow the below commands:

Zsh

mkdir -p ~/.pyepp
_PYEPP_COMPLETE=zsh_source pyepp > ~/.pyepp/shell-complete.zsh

Source the file in ~/.zshrc.

. ~/.pyepp/shell-complete.zsh

Bash

mkdir -p ~/.pyepp
_PYEPP_COMPLETE=bash_source pyepp > ~/.pyepp/shell-complete.bash

Source the file in ~/.bashrc.

. ~/.pyepp/shell-complete.bash
