You can enable or disable mTLS from the Cryptographic Security Platform Vault for Cryptographic APIs webGUI.

1. Log into the Cryptographic Security Platform Vault for Cryptographic APIs webGUI.

2. At the top right of the vault page, click the Settings icon.

3. On the Settings page, click the mTLS tab.

4. Toggle the mTLS button to Enabled or Disabled.

5. Confirm your choice.

You can also use the UpdateTokenizationSettings API to enable mTLS. The path to this API does not change when mTLS is enabled. It is always https://<VAULT_IP_Address>/token/1.0/key/UpdateTokenizationSettings.

For example: 

Copy

{
  "2FA_enforced": false,
  "degraded_mode_availability": false,
  "mTLS_enabled": true,
  "oidc_enabled": true,
  "revision": 1
}
