Self Signed Cert

This ansible role allows for generating self-signed certificates. As a result, it will generate 3 pem certificates with keys: ca, client and server. Additionally to that, it will also generate 2 pfx certificates for client and server.

General variables

Certificate dir

self_signed_cert_dir: /etc/certs/

This is a directory where certificates will be saved.

cfssl and cfssl_json download url

self_signed_cert_cfssl_url: https://pkg.cfssl.org/R1.2/cfssl_linux-amd64
self_signed_cert_cfssl_json_url: https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64

You can specify which version of cfssl and cfssl_tool you want to download.

Profiles

self_signed_cert_profiles:
  - name: server
    expirity: 8760h
    usages:
      - signing
      - key encipherment
      - server auth
      - client auth

cfssl support multiple profiles. Each profiles has it own unique name. The expirity date determinates when the certificate generated using this profile will be expired. The usages determinates purpose of the certificate. Allowed values are:

• Key Usages: signing, digital signature, content committment, key encipherment, key agreement, data encipherment, cert sign, crl sign, encipher only, decipher only,
• Ext Key Usages: any, server auth, client auth, code signing, email protection, s/mime, ipsec end system, ipsec tunnel, ipsec user, timestamping, ocsp signing, microsoft sgc, netscape sgc

Certificate authority

self_signed_cert_ca_certs:
  - name: example-ca
    cn: example.com
    key_algo: rsa
    key_size: 2048
    country: EU
    location: Internet
    organisation: Example
    organisation_unit: IT
    state: internet
    trust_ca_cert: false

Certificate authority key_algo can has one of values: ECDSA256, RSA. trust_ca_cert will inject ca certificated to the trusted root certificates.
