# Enable TLS on Lenses

{% hint style="success" %}
TLS settings go in **security.conf.**
{% endhint %}

## Global Truststore

To use a non-default global truststore, set the path in accordingly with the LENSES\_OPTS variable.

```
LENSES_OPTS=-Djavax.net.ssl.trustStore=/path/to/truststore
```

## Custom Truststore

To use a custom truststore set the following in **security.conf.** Supported types: `jks, pkcs12`.

{% code title="security.conf" %}

```bash
lenses.ssl.truststore.location = "/path/to/truststore.jks"
lenses.ssl.truststore.password = "changeit"
```

{% endcode %}

## Mutual TLS

To enable mutual TLS, set your keystore accordingly.

{% code title="security.conf" %}

```bash
# To secure and encrypt all HTTPS connections to Lenses via TLS termination.
# Java Keystore location and passwords
lenses.ssl.client.auth = true
lenses.ssl.keystore.location = "/path/to/keystore.jks"
lenses.ssl.keystore.password = "changeit"
lenses.ssl.key.password      = "changeit"


# You can also tweak the TLS version, algorithm and ciphers
#lenses.ssl.enabled.protocols = "TLSv1.2"
#lenses.ssl.cipher.suites     = "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_RSA_WIT
```

{% endcode %}
