x509 extensions in other CAs¶
This page documents the x509 extensions (e.g. for CRLs, etc.) set by other CAs. The information here is used by django-ca to initialize and sign certificate authorities and certificates.
Helpful descriptions of the meaning of various extensions can also be found in x509v3_config(5SSL) (online).

Issuer¶
The issuer is an X509 Name naming who signed the certificate. For root CAs, the issuer has the same value as the subject.

BasicConstraints¶
The BasicConstraints extension specifies if the certificate can be used as a certificate authority. It is
always marked as critical. The path_length attribute specifies the levels of possible intermediate CAs. If
not present, the level of intermediate CAs is unlimited, a path_length:0 means that the CA itself can not
issue certificates with CA:TRUE itself.
In CA certificates¶
Most root CAs do not set a Path Length, while most (but not all) intermediate CAs set a Path Length of 0.

CRLDistributionPoints¶
In theory a complex multi-valued extension, this extension usually just holds a URI pointing to a Certificate Revocation List (CRL).
Root certificate authorities (StartSSL, GeoTrust Global, GlobalSign) do not set this field. This usually isn’t a problem since clients have a list of trusted root certificates anyway, and browsers and distributions should get regular updates on the list of trusted certificates.
All CRLs linked here are all in DER/ASN1 format, and the Content-Type header in the response is
set to application/pkix-crl. Only Comodo uses application/x-pkcs7-crl, but it is also in
DER/ASN1 format.

In signed certificates¶
Let’s Encrypt is so far the only CA that does not maintain a CRL for signed certificates. Major CAs usually don’t fancy CRLs much because they are a large file (e.g. the CRL from Comodo is 1.5MB) containing all certificates and cause major traffic for CAs. OCSP is just better in every way.
