Technical Requirements

Please note the know technical restrictions, that have to be covered by the client system.

  • TLS (Transport Layer Security) 1.2
    The client has to support TLS 1.2 as this is the only allowed Protocol to establish a secure connection to the API Gateway. Currently the following Cipher Suites are supported:
    • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)
    • TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (0xc02f) 
    • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028)
    • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 (0xc027)
       
  • SNI (Server Name Indication)
    Your client system must support SNI (Server Name Identication). This is enabled for almost all modern clients by default.

    For SAP client systems please set the following parameters:
    • icm/HTTPS/client_sni_enabled = TRUE
    • ssl/client_sni_enabled = TRUE
