Configuration of TLS encryption¶

To configure the minimum/maximum TLS version, you need to edit the configuration file server/tls.json.

{
  "min_version": "TLSv1.2",
  "max_version": "TLSv1.3",
  "ciphers": "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256:TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256"
 }

Description of file parameters:

Parameter	Type	Description
`min_version`	`string`	TLS minimal version
`max_version`	`string`	TLS maximal version
`ciphers`	`string`	allowed algorithms, you can specify more than one with a separator `:` Possible values: `TLS_RSA_WITH_AES_128_CBC_SHA` `TLS_RSA_WITH_AES_256_CBC_SHA` `TLS_RSA_WITH_AES_128_GCM_SHA256` `TLS_RSA_WITH_AES_256_GCM_SHA384` `TLS_AES_128_GCM_SHA256` `TLS_AES_256_GCM_SHA384` `TLS_CHACHA20_POLY1305_SHA256` `TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA` `TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA` `TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA` `TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA` `TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256` `TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384` `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256` `TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384` `TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256` `TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256`
