Configure cipher suites

Due to regulatory compliance or other security requirements, you may need to change which cipher suites your SSL-enabled PE services use to communicate with other PE components.

SSL ciphers for core Puppet services

To add or remove cipher suites for core Puppet services, use Hiera to add an array of SSL ciphers to the puppet_enterprise::ssl_cipher_suites parameter.
Note: Changing this parameter overrides the default list of SSL cipher suites.
The example Hiera data below replaces the default list of cipher suites to only allow the four specified.
puppet_enterprise::ssl_cipher_suites:
- 'SSL_RSA_WITH_NULL_MD5'
- 'SSL_RSA_WITH_NULL_SHA'
- 'TLS_DH_anon_WITH_AES_128_CBC_SHA'
- 'TLS_DH_anon_WITH_AES_128_CBC_SHA256'
Note: Cipher names are in IANA RFC naming format.

SSL for console services

To add or remove cipher suites for console services affecting traffic on port 443, use Hiera or the console to change the puppet_enterprise::profile::console::proxy::ssl_ciphers parameter.

For example, to change the parameter in the console, in the PE Console node group, add an array of SSL ciphers to the ssl_ciphers parameter in the puppet_enterprise::profile::console::proxy class.
