[Sebastian_Linser]

If a specific set of ciphers for the Qlik NPrinting License Service is required, there is the inbuilt possibility to configure those.

Environment

• Qlik Nprinting Feb 2021 and newer

Resolution

Open the file C:\Program Files\NPrintingServer\NPrinting\License\license.config and at the end of the file keep only the cipher suites they want as in the example below:

<!--Add a custom comma-separated list of cipher suites as shown below-->
  <add key="cipher-suites" value="TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384" />

The available ciphers to configure are:

• TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
• TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
• TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA25
• TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
• TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305
• TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305
• TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
• TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA
• TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
• TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
• TLS_RSA_WITH_AES_128_GCM_SHA256
• TLS_RSA_WITH_AES_256_GCM_SHA384
• TLS_RSA_WITH_AES_128_CBC_SHA
• TLS_RSA_WITH_AES_256_CBC_SHA
• TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA
• TLS_RSA_WITH_3DES_EDE_CBC_SHA
