SSL Connection Description

SSL (Secure Sockets Layer) is the protocol for secure access to remote computers over insecure communication channels.

The SSL protocol runs above TCP/IP and below higher-level database protocol. It uses TCP/IP on behalf of the higher-level protocols, and in the process allows an SSL-enabled server to authenticate itself to an SSL-enabled client, allows the client to authenticate itself to the server, and allows both machines to establish an encrypted connection.

These capabilities address fundamental concerns about communication over the Internet and other TCP/IP networks:

SSL is based on algorithms of asymmetric encryption and digital signature. Consult ASE Reference Manual for information about Setting up SSL in ASE and Open Client and Configuring SSL .


Usage of SSL is more preferable for ASE connections than SSH because of less required settings and higher performance.

How to connect to ASE using SSL

To use SSL encryption for connection to ASE, the corresponding SSL connection options should be set:
