esteid-certificates 1.0.2

Certificates for Estonian e-identity services

esteid-certificates

This library contains certificates for Estonian electronic identity services and a couple of functions that facilitate usage.

The library covers the following use cases:

• embedding the root certificate of the Estonian Certification centre into an XML signature structure prior to signing;
• obtaining OCSP confirmation of the signer's certificate after signing: the OCSP request must contain an issuer certificate that corresponds to the issuer's common name as included in the signer's certificate.

API

Get a certificate by issuer's common name:

from esteid_certificates import get_certificate_file_name, get_certificate
# path to PEM certificate file
assert get_certificate_file_name("EID-SK 2016").endswith(".pem")
# the certificate as bytes
assert get_certificate("EID-SK 2016").startswith(b"-----BEGIN CERTIFICATE-----")

Get the root certificate:

from esteid_certificates import get_root_ca_file_name, get_root_certificate
# path to PEM certificate file
assert get_root_ca_file_name().endswith(".pem")
# the certificate as bytes
assert get_root_certificate().startswith(b"-----BEGIN CERTIFICATE-----")

Get the TEST root certificate:

from esteid_certificates import get_root_ca_file_name, get_root_certificate
# path to PEM certificate file
assert get_root_ca_file_name(test=True).endswith(".pem")
# the certificate as bytes
assert get_root_certificate(test=True).startswith(b"-----BEGIN CERTIFICATE-----")

The certificates can be loaded using e.g. the oscrypto library:

from oscrypto.asymmetric import load_certificate
cert = load_certificate(get_certificate("EID-SK 2016"))
assert cert.asn1.native['tbs_certificate']['subject']['common_name'] == 'EID-SK 2016'

Certificates

The certificates were downloaded from the certificate page.

The included certificates are copyright to their issuing parties:
