Negotiates a Transport Layer Security (TLS) connection on the specified TCP socket as a server. If successful, the connection is transparently encrypted. Otherwise, the connection is closed.

Inputs/Outputs

  • ci32.png timeout ms —

    timeout ms specifies the time, in milliseconds, that the function waits before timing out. A value of –1 indicates to wait indefinitely. The default value is 25000.

  • cncrn.png TCP connection —

    TCP connection specifies the network connection reference that uniquely identifies the TCP connection.

  • cgnrn.png immutable TLS configuration —

    immutable TLS configuration specifies the reference to the immutable TLS configuration.

  • cerrcodeclst.png error in —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • incrn.png TLS connection —

    TLS connection returns a network connection reference that uniquely identifies the TLS connection. Use this value to refer to this TLS connection in subsequent function calls.

  • i1dcclst.png client certificate chain —

    client certificate chain returns an array of Distinguished Encoding Rules (DER) certificates provided by the client. The first element of the array is the certificate of the client.

  • i1du8.png certificate —

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.

    • Note If TLS negotiation fails, TCP connection is closed, and future calls to TLS Connection? will return FALSE.
