# Certain Cipher suites are not shown in ssl server test

Hi, I am running version 15.1.0.

I configured client-ssl profile with cipher group as I need to enable TLSv1.3

The cipher group has a rule which enables certain cipher suites only:

TLSv1_3:ECDHE_ECDSA+AES-GCM:ECDHE+AES-GCM:ECDHE+AES:ECDHE_ECDSA+CHACHA20-POLY1305:ECDHE+CHACHA20-POLY1305:!DHE+AES-GCM:!TLSv1:!TLSv1_1:!ECDHE+AES:@STRENGTH

With this I am receiving the following into the Rule Audit tab:

**Cipher Suites**

**TLS13-AES256-GCM-SHA384/TLS1.3****TLS13-CHACHA20-POLY1305-SHA256/TLS1.3****ECDHE-ECDSA-AES256-GCM-SHA384/TLS1.2****ECDHE-RSA-AES256-GCM-SHA384/TLS1.2****ECDHE-ECDSA-CHACHA20-POLY1305-SHA256/TLS1.2****ECDHE-RSA-CHACHA20-POLY1305-SHA256/TLS1.2****TLS13-AES128-GCM-SHA256/TLS1.3****ECDHE-ECDSA-AES128-GCM-SHA256/TLS1.2****ECDHE-RSA-AES128-GCM-SHA256/TLS1.2**

**DH Groups**

**DEFAULT**

**Signature Algorithms**

**DEFAULT**

The problem is when I check the site into ssl labs , it gives me only these ciphers :

Cipher Suites

# TLS 1.3 (suites in server-preferred order)

TLS_AES_256_GCM_SHA384 (0x1302)ECDH secp384r1 (eq. 7680 bits RSA) FS256

TLS_CHACHA20_POLY1305_SHA256 (0x1303)ECDH secp384r1 (eq. 7680 bits RSA) FS256

TLS_AES_128_GCM_SHA256 (0x1301)ECDH secp384r1 (eq. 7680 bits RSA) FS128

# TLS 1.2 (suites in server-preferred order)

TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)ECDH secp384r1 (eq. 7680 bits RSA) FS256

TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 (0xcca8)ECDH secp384r1 (eq. 7680 bits RSA) FS256

TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (0xc02f)ECDH secp384r1 (eq. 7680 bits RSA) FS128

TLSv1.3 is enabled into the client-ssl profile

no-tlsv1.1

no-tlsv1

I also have serverssl profile attached to the VIP. Cannot find a way to see ECDHE-ECDSA into the ssl labs...

Yes, they are properly assigned. When I change the CIpher rule which is:

TLSv1_3:ECDHE_ECDSA+AES-GCM:ECDHE+AES-GCM:ECDHE+AES:ECDHE_ECDSA+CHACHA20-POLY1305:ECDHE+CHACHA20-POLY1305:!DHE+AES-GCM:!TLSv1:!TLSv1_1:!ECDHE+AES:@STRENGTH

I see differencies when checking the ciphers but only ECDHE_ECDSA are not visible into the ssllabs.

I even tried with openssl and sslscan tools via linux and didn't saw it as well....

I just found out the reason. The certificate is created as RSA. which means :

**RSA**: Specifies that the key is based on the RSA public key encryption algorithm.So no ECDSA will be presented even allowed in the cipher suite....
