+   Enabled TLS cipher suites. The supported ciphers are:
+
+    - TLS 1.0 - 1.2 cipher suites:
+        - TLS_RSA_WITH_RC4_128_SHA
+        - TLS_RSA_WITH_3DES_EDE_CBC_SHA
+        - TLS_RSA_WITH_AES_128_CBC_SHA
+        - TLS_RSA_WITH_AES_256_CBC_SHA
+        - TLS_RSA_WITH_AES_128_CBC_SHA256
+        - TLS_RSA_WITH_AES_128_GCM_SHA256
+        - TLS_RSA_WITH_AES_256_GCM_SHA384
+        - TLS_ECDHE_ECDSA_WITH_RC4_128_SHA
+        - TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA
+        - TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
+        - TLS_ECDHE_RSA_WITH_RC4_128_SHA
+        - TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA
+        - TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
+        - TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
+        - TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
+        - TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
+        - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
+        - TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
+        - TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
+        - TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
+        - TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256
+        - TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256
+
+    - TLS 1.3 cipher suites:
+        - TLS_AES_128_GCM_SHA256
+        - TLS_AES_256_GCM_SHA384
+        - TLS_CHACHA20_POLY1305_SHA256
+        - TLS_FALLBACK_SCSV isn't a standard cipher suite but an indicator that the client is doing version fallback
+        - TLS_FALLBACK_SCSV uint16 = 0x5600
+        - TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305   = TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256
+        - TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305 = TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA25
+
+   For detailed information on ciphers, refer to the Golang `tls.TLS_* <https://pkg.go.dev/crypto/tls#pkg-constants>`__ constants.
