The `set ssl_tls_ciphers` command allows you to enable or disable the SSL/TLS ciphers for APACHE and SAML services only. You can enable any specific cipher suite or all the cipher suites. The default cipher suites are enabled in a specific order. However, you can change this default order. Note that you cannot disable all the cipher suites. At least one cipher suite must be enabled.

The default cipher suites are enabled in the following order:

1. `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 `
2. `TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384`
3. `TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA `
4. `TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA `
5. `TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 `
6. `TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 `
7. `TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 `
8. `TLS_DHE_RSA_WITH_AES_128_CBC_SHA `
9. `TLS_DHE_RSA_WITH_AES_256_CBC_SHA`
10. `TLS_DHE_RSA_WITH_AES_128_CBC_SHA256`
11. `TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 `
12. `TLS_RSA_WITH_AES_128_GCM_SHA256 `
13. `TLS_RSA_WITH_AES_128_CBC_SHA`
14. `TLS_RSA_WITH_AES_128_CBC_SHA256 `
15. `TLS_RSA_WITH_3DES_EDE_CBC_SHA`
16. `TLS_RSA_WITH_AES_256_GCM_SHA384 `
17. `TLS_RSA_WITH_AES_256_CBC_SHA  `
18. `TLS_RSA_WITH_AES_256_CBC_SHA256 `
19. `TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256`
20. `TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 `
21. `TLS_AES_256_GCM_SHA384 `
22. `TLS_CHACHA20_POLY1305_SHA256 `
23. `TLS_AES_128_GCM_SHA25 `
24. `TLS_AES_128_CCM_8_SHA256 `
25. `TLS_AES_128_CCM_SHA256`

You can also enable the following cipher suites that are disabled by default:

- `TLS_DHE_DSS_WITH_AES_256_CBC_SHA `
- `TLS_DH_RSA_WITH_3DES_EDE_CBC_SHA `
- `TLS_DH_DSS_WITH_3DES_EDE_CBC_SHA`
- `TLS_DHE_DSS_WITH_AES_128_CBC_SHA `
- `TLS_RSA_WITH_RC4_128_SHA`
- `TLS_DHE_DSS_WITH_AES_256_GCM_SHA384 `
- `TLS_DHE_DSS_WITH_AES_256_CBC_SHA256 `
- `TLS_DHE_DSS_WITH_AES_128_GCM_SHA256 `
- `TLS_DHE_DSS_WITH_AES_128_CBC_SHA256 `

You can use the `show ssl_tls_ciphers` command to view the enabled SSL/TLS cipher suites. For information, see *[show ssl_tls_ciphers](https://infoblox-docs.atlassian.net/wiki/spaces/nios90/pages/415531149)*.

# Syntax

`set ssl_tls_ciphers enable suite_name [ position ]`  
`set ssl_tls_ciphers disable position`  
`set ssl_tls_ciphers enable_all`

| **Argument** | **Description** |
| --- | --- |
| `enable` | Enables the cipher suites. |
| `suite_name` | Specifies the name of a particular cipher suite. |
| `all` | Enables all cipher suites. |
| `position` | Specifies the position of a cipher suite. |
| `disable` | Disables the cipher suites. |

# Examples

## Enable all cipher suites

`Infoblox > set ssl_tls_ciphers enable_all`  
`All cipher suites were enabled`  
`The following services need to be restarted manually: GUI`

## Enable a specific cipher suite

`Infoblox > set ssl_tls_ciphers enable TLS_RSA_WITH_RC4_128_SHA 9`  
`TLS_RSA_WITH_RC4_128_SHA was enabled`  
`The following services need to be restarted manually: GUI`

## Disable a specific cipher suite

`Infoblox > set ssl_tls_ciphers disable 8`  
`TLS_DHE_RSA_WITH_AES_128_CBC_SHA`

`The following services need to be restarted manually: GUI`

> ⚠️ **Note**
> ⚠️ 
> ⚠️ - From NIOS 9.0.4:
> ⚠️   - Disabling the last cipher suite for an enabled TLS protocol is not allowed.
> ⚠️   - The `set ssl_tls_ciphers` CLI command cannot be used to enable/disable TLSv1.3 ciphers for SAML. By default, SAML service uses only the following three TLSv1.3 ciphers, if the TLSv1.3 protocol is enabled in NIOS.
> ⚠️     - TLS_AES_256_GCM_SHA384
> ⚠️     - TLS_CHACHA20_POLY1305_SHA256
> ⚠️     - TLS_AES_128_GCM_SHA256
> ⚠️   - Apache/SAML service is not affected by enabling/disabling the TLS cipher suites of a disabled TLS Protocol.
> ⚠️ - Starting from NIOS 9.0, the weak ciphers(RC4 and 3DES for APACHE) and (RC4 and 3DES, and DHE for SAML) are deprecated.
> ⚠️ - It is recommended to avoid enabling only the following ciphers, as this will affect the APACHE/SAML services.
