# HTTPS & TLS
Traefik supports HTTPS & TLS, and is able to accept new certificates / updates over time (without being restarted).
TLS is enabled at the [router](../routing/routers/index.md) level, but some options are configured in dedicated sections (`tlsOptions` & `tlsStores`) described in this section.
## Configuration Example
??? example "Configuring a Default Certificate"
```toml
[tlsStores]
[tlsStores.default]
[tlsStores.default.defaultCertificate]
certFile = "path/to/cert.crt"
keyFile = "path/to/cert.key"
```
??? example "Configuring a Minimum TLS Version"
```toml
[tlsOptions]
[tlsOptions.default]
minVersion = "VersionTLS12"
```
??? example "Defining Certificates"
```toml
[[tls]]
[tls.certificate]
certFile = "/path/to/domain.cert"
keyFile = "/path/to/domain.key"
[[tls]]
[tls.certificate]
certFile = "/path/to/other-domain.cert"
keyFile = "/path/to/other-domain.key"
```
!!! important "File Provider Only"
In the above example, we've used the [file provider](../providers/file.md) to handle the TLS configuration (tlsStores, tlsOptions, and TLS certificates).
In its current alpha version, it is the only available method to configure these elements.
Of course, these options are hot reloaded and can be updated at runtime (they belong to the [dynamic configuration](../getting-started/configuration-overview.md)).
## Configuration Options
### Dynamic Certificates
To add / remove TLS certificates while Traefik is running, the [file provider](../providers/file.md) supports Dynamic TLS certificates in its `[[tls]]` section.
!!! example "Defining Certificates"
```toml
[[tls]]
stores = ["default"]
[tls.certificate]
certFile = "/path/to/domain.cert"
keyFile = "/path/to/domain.key"
[[tls]]
stores = ["default"]
[tls.certificate]
certFile = "/path/to/other-domain.cert"
keyFile = "/path/to/other-domain.key"
```
??? note "Stores"
During the alpha version, the stores option will be ignored and be automatically set to ["default"].
### Mutual Authentication
Traefik supports both optional and non optional (defaut value) mutual authentication.
- When `optional = false`, Traefik accepts connections only from client presenting a certificate signed by a CA listed in `ClientCA.files`.
- When `optional = true`, Traefik authorizes connections from client presenting a certificate signed by an unknown CA.
!!! example "Non Optional Mutual Authentication"
In the following example, both `snitest.com` and `snitest.org` will require client certificates.
```toml
[tlsOptions]
[tlsOptions.default]
[tlsOptions.default.ClientCA]
files = ["tests/clientca1.crt", "tests/clientca2.crt"]
optional = false
```
??? note "ClientCA.files"
You can use a file per `CA:s`, or a single file containing multiple `CA:s` (in `PEM` format).
`ClientCA.files` is not optional: every client will have to present a valid certificate. (This requirement will apply to every server certificate declared in the entrypoint.)
### Minimum TLS Version
!!! example "Min TLS version & [cipherSuites](https://godoc.org/crypto/tls#pkg-constants)"
```toml
[tlsOptions]
[tlsOptions.default]
minVersion = "VersionTLS12"
cipherSuites = [
"TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256",
"TLS_RSA_WITH_AES_256_GCM_SHA384"
]
```
### Strict SNI Checking
With strict SNI checking, Traefik won't allow connections without a matching certificate.
!!! example "Strict SNI"
```toml
[tlsOptions]
[tlsOptions.default]
sniStrict = true
```
### Default Certificate
Traefik can use a default certificate for connections without a SNI, or without a matching domain.
If no default certificate is provided, Traefik generates and uses a self-signed certificate.
!!! example "Setting a Default Certificate"
```toml
[tlsStores]
[tlsStores.default]
[tlsStores.default.defaultCertificate]
certFile = "path/to/cert.crt"
keyFile = "path/to/cert.key"
```
??? note "Only One Default Certificate"
There can only be one `defaultCertificate` per tlsOptions.
??? note "Default TLS Store"
During the alpha version, there is only one globally available TLS Store (`default`).

# HTTPS & TLS
Overview
{: .subtitle }
Traefik supports HTTPS & TLS, which concerns roughly two parts of the configuration:
routers, and the TLS connection (and its underlying certificates).
When a router has to handle HTTPS traffic,
it should be specified with a `tls` field of the router definition.
See the TLS section of the [routers documentation](../routing/routers/index.md#tls).
The next sections of this documentation explain how to configure the TLS connection itself.
That is to say, how to obtain [TLS certificates](./tls.md#certificates-definition):
either through a definition in the dynamic configuration, or through [Let's Encrypt](./acme.md) (ACME).
And how to configure [TLS options](./tls.md#tls-options), and [certificates stores](./tls.md#certificates-stores).

## Certificates Definition
### Automated
See the [Let's Encrypt](./acme.md) page.
### User defined
To add / remove TLS certificates, even when Traefik is already running, their definition can be added to the [dynamic configuration](../getting-started/configuration-overview.md), in the `[[tls]]` section:
```toml
[[tls]]
[tls.certificate]
certFile = "/path/to/domain.cert"
keyFile = "/path/to/domain.key"
[[tls]]
[tls.certificate]
certFile = "/path/to/other-domain.cert"
keyFile = "/path/to/other-domain.key"
```
!!! important "File Provider Only"
In the above example, we've used the [file provider](../providers/file.md) to handle these definitions.
In its current alpha version, it is the only available method to configure the certificates (as well as the options and the stores).
## Certificates Stores
In Traefik, certificates are grouped together in certificates stores, which are defined as such:
```toml
[tlsStores]
[tlsStores.default]
```
!!! important "Alpha restriction"
During the alpha version, any store definition other than the default one (named `default`) will be ignored,
and there is thefore only one globally available TLS store.
In the `[[tls]]` section, a list of stores can then be specified to indicate where the certificates should be stored:
```toml
[[tls]]
stores = ["default"]
[tls.certificate]
certFile = "/path/to/domain.cert"
keyFile = "/path/to/domain.key"
[[tls]]
# Note that since no store is defined,
# the certificate below will be stored in the `default` store.
[tls.certificate]
certFile = "/path/to/other-domain.cert"
keyFile = "/path/to/other-domain.key"
```
!!! important "Alpha restriction"
During the alpha version, the `stores` list will actually be ignored and automatically set to `["default"]`.
### Default Certificate
Traefik can use a default certificate for connections without a SNI, or without a matching domain.
This default certificate should be defined in a TLS store:
```toml
[tlsStores]
[tlsStores.default]
[tlsStores.default.defaultCertificate]
certFile = "path/to/cert.crt"
keyFile = "path/to/cert.key"
```
If no default certificate is provided, Traefik generates and uses a self-signed certificate.
## TLS Options
The TLS options allow one to configure some parameters of the TLS connection.
### Minimum TLS Version
```toml
[tlsOptions]
[tlsOptions.default]
minVersion = "VersionTLS12"
[tlsOptions.mintls13]
minVersion = "VersionTLS13"
```
### Mutual Authentication
Traefik supports both optional and strict (which is the default) mutual authentication, though the `ClientCA.files` section.
If present, connections from clients without a certificate will be rejected.
For clients with a certificate, the `optional` option governs the behaviour as follows:
- When `optional = false`, Traefik accepts connections only from clients presenting a certificate signed by a CA listed in `ClientCA.files`.
- When `optional = true`, Traefik authorizes connections from clients presenting a certificate signed by an unknown CA.
```toml
[tlsOptions]
[tlsOptions.default]
[tlsOptions.default.ClientCA]
# in PEM format. each file can contain multiple CAs.
files = ["tests/clientca1.crt", "tests/clientca2.crt"]
optional = false
```
### Cipher Suites
See [cipherSuites](https://godoc.org/crypto/tls#pkg-constants) for more information.
```toml
[tlsOptions]
[tlsOptions.default]
cipherSuites = [
"TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256",
"TLS_RSA_WITH_AES_256_GCM_SHA384"
]
```
### Strict SNI Checking
With strict SNI checking, Traefik won't allow connections from clients connections
that do not specify a server_name extension.
```toml
[tlsOptions]
[tlsOptions.default]
sniStrict = true
```
