Supported TLS cipher suites
AtScale supports a few sets of TLS 1.2 cipher suites: one for the Web front-end, one for the engine, and one for LDAPS connections.
Front-end
The AtScale front-end application supports these cipher suites:
- TLS_RSA_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
info
Important: It is not recommended to use the TLS_RSA_WITH_AES_256_GCM_SHA384 cipher.
If you need to configure which of these are enabled:
-
Log in to the system where AtScale is installed.
-
Open the
/opt/atscale/current/conf/modeler/app.conf
file with a text editor. -
Add the
http.ssl.cipherSuites
setting, as shown in the example below; or update it, if it is present:http.ssl.cipherSuites="TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256"
Note the following:
- This is an example with two suites specified. Set your own suites as needed.
- The suites must be separated with comma signs (,).
- The list of suites must be in quotes, as shown in the example.
