> Key: CASSANDRA-13428
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13428
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Feature/Encryption, Local/Config
> Reporter: Bas van Dijk
> Assignee: Maulin Vasavada
> Priority: Normal
> Fix For: 5.1
>
> Original Estimate: 3h
> Time Spent: 3h 50m
> Remaining Estimate: 0h

> Currently passwords are stored in plaintext in the configuration file as in:
> {code}
> server_encryption_options:
> keystore_password: secret
> truststore_password: secret
> client_encryption_options:
> keystore_password: secret
> {code}
> This has the disadvantage that, in order to protect the secrets, the whole
> configuration file needs to have restricted ownership and permissions. This
> is problematic in operating systems like NixOS where configuration files are
> usually stored in world-readable locations.
> A secure option would be to store secrets in files (with restricted ownership
> and permissions) and reference those files from the unrestricted
> configuration file as in for example:
> {code}
> server_encryption_options:
> keystore_password_file: /run/keys/keystore-password
> truststore_password_file: /run/keys/truststore-password
> client_encryption_options:
> keystore_password_file: /run/keys/keystore-password
> {code}
> This is trivial to implement and provides a big gain in security.
> So in summary I'm proposing to add the {{keystore_password_file}} and
> {{truststore_password_file}} options besides the existing
> {{keystore_password}} and {{truststore_password options}}. The former will
> take precedence over the latter.
