Use DescribeSslPolicies with a CLI

Example 1: To list the policies used for SSL negotiation by load balancer type

The following describe-ssl-policies example displays the names of the polices that you can use for SSL negotiation with an Application Load Balancer. The example uses the --query parameter to display only the names of the policies.

aws elbv2 describe-ssl-policies \
    --load-balancer-type application \
    --query SslPolicies[*].Name

Output:

[
    "ELBSecurityPolicy-2016-08",
    "ELBSecurityPolicy-TLS13-1-2-2021-06",
    "ELBSecurityPolicy-TLS13-1-2-Res-2021-06",

    "ELBSecurityPolicy-FS-1-2-2019-08",
    "ELBSecurityPolicy-FS-1-2-Res-2020-10"
]

Example 2: To list the policies that support a specific protocol

The following describe-ssl-policies example displays the names of the polices that support the TLS 1.3 protocol. The example uses the --query parameter to display only the names of the policies.

aws elbv2 describe-ssl-policies \
    --load-balancer-type application \
    --query SslPolicies[?contains(SslProtocols,'TLSv1.3')].Name

Output:

[
    "ELBSecurityPolicy-TLS13-1-2-2021-06",
    "ELBSecurityPolicy-TLS13-1-2-Res-2021-06",
    "ELBSecurityPolicy-TLS13-1-2-Ext1-2021-06",
    "ELBSecurityPolicy-TLS13-1-2-Ext2-2021-06",
    "ELBSecurityPolicy-TLS13-1-1-2021-06",
    "ELBSecurityPolicy-TLS13-1-0-2021-06",
    "ELBSecurityPolicy-TLS13-1-3-2021-06"
]

Example 3: To display the ciphers for a policy

The following describe-ssl-policies example displays the names of the ciphers for the specified policy. The example uses the --query parameter to display only the cipher names. The first cipher in the list has priority 1, and the remaining ciphers are in priority order.

aws elbv2 describe-ssl-policies \
    --names ELBSecurityPolicy-TLS13-1-2-2021-06 \
    --query SslPolicies[*].Ciphers[*].Name

Output:

[
    "TLS_AES_128_GCM_SHA256",
    "TLS_AES_256_GCM_SHA384",
    "TLS_CHACHA20_POLY1305_SHA256",
    "ECDHE-ECDSA-AES128-GCM-SHA256",
    "ECDHE-RSA-AES128-GCM-SHA256",
    "ECDHE-ECDSA-AES128-SHA256",
    "ECDHE-RSA-AES128-SHA256",
    "ECDHE-ECDSA-AES256-GCM-SHA384",
    "ECDHE-RSA-AES256-GCM-SHA384",
    "ECDHE-ECDSA-AES256-SHA384",
    "ECDHE-RSA-AES256-SHA384"
]
