The 'Using the OpenSSL' section provides a guide to connecting to the SSL server through OpenSSL
Required Hardware and Software
WIZ510SSL-RS232/TTL-EVB Evaluation Board
Cables (Ethernet / Serial / Micro USB Type B)
WIZnet S2E Configuration Tool
How to Connect to SSL Server through OpenSSL
Step 1: Set up environment to use the WIZ510SSL
The process of set up environment to use the WIZ510SS is available at the WIZ510SSL Getting Started page.
Step 2: Set up and run the SSL server through OpenSSL
- Set up the SSL server
genrsa -des3 -out [key_name].key 2048 // Create the private key
req -new -key [key_name].key -out [csr_name].csr // Create the CSR(Required for certificate signing request)
x509 -req -days [days] -in [csr_name].csr -signkey [key_name].key -out [crt_name].crt // Create the certificate
genrsa -des3 -out server.key 2048
req -new -key server.key -out server.csr
x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
- Run the SSL server
s_server -accept [port] -cert [crt_name].crt -key [key_name].key // Run SSL the server
s_server -accept 443 -cert server.crt -key server.key
Step 3: Set up the WIZ510SSL through the WIZnet S2E Configuration Tool for SSL server connection
- Select SSL TCP client mode in the Operation mode setting section
|Figure: Select SSL TCP client mode|
- Input the remote host IP (or URL) and remote port in the Remote host / port section
|Figure: Input the remote host IP and remote port|
- Click the Apply Settings button to save the settings
|Figure: Click the Apply Settings button|
| Figure: Saved settings
※ Note: If you need certificates to connect to SSL server, please refer to the 'Upload Certificates' section below.
Step 4: Done
WIZ510SSL is successfully connected to SSL server through OpenSSL!

You can upload certificates below in the 'Certificate manager' tab of the'WIZnet S2E Configuration Tool'.
- Root CA
- Client Certificate
- Private key
Upload and set up the certificates required by the SSL server you want to connect to.
After loading the certificate by clicking the 'Load file' button, be sure to save it by clicking the 'Save to device' button.
