If the kernel / OS won't allow lowering the TLS then a custom openssl.conf likely won't either. You can't override the kernel / OS to lower security.

Since it is already a security lowering snowflake, IMHO it is good to make this explicit by having it done in a custom shell/command. It is simple, easy, and makes it very clear what is going on for this specific device.

Exactly, and this is why I currently have to use a custom weakened openssl.cnf by the curl-based Ansible playbook. However, the environment variable OPENSSL_CONF, referring to the custom OpenSSL config, is ignored when I use "ansible.builtin.uri". Actually, "ansible.builtin.uri" even ignores by OpenSSL config located in the default path /etc/ssl/openssl.cnf on my Debian 12.6 system: -----BEGIN SHELL----- $ cat /etc/ssl/openssl.cnf openssl_conf = openssl_init [openssl_init] ssl_conf = ssl_sect [ssl_sect] system_default = system_default_sect [system_default_sect] MinProtocol = TLSv1 CipherString = DEFAULT@SECLEVEL=0 Options = UnsafeLegacyRenegotiation $ ansible-playbook -vvv test.yml ... "msg": "Status code was -1 and not [200]: Request failed: <urlopen error [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:1000)>", ... -----END SHELL----- Thank you.

TLS 1.0 is compromised and therefore no longer allowed by many systems. What platform is your control host?

Yes, I did. However, the result is the same: Ansible controller is not happy with the bare TLS 1.0 reply from the legacy box: "msg": "Status code was -1 and not [200]: Request failed: <urlopen error [SSL: UNSUPPORTED_PROTOCOL] unsupported protocol (_ssl.c:1000)>" - name: Query legacy boxes hosts: legacyboxes gather_facts: false connection: local tasks: - name: GET the home page ansible.builtin.uri: url: https://{{ ansible_host }} ciphers: - 'DEFAULT@SECLEVEL=0' Again, ciphers-wise, the setup is fine, but I do not think it is possible to enforce the minimum TLS protocol version with the cipher string.
