How to Connect to SSL Server through OpenSSL
Step 1: Setup Environment to Use WIZ5xxSR-RP
The process of setup environment to use the WIZ5xxSR-RP each product is available at the 'Getting Started' document below.
Step 2: Setup OpenSSL
Setup OpenSSL to use as the SSL Server.
genrsa -des3 -out [key_name].key 2048
req -new -key [key_name].key -out [csr_name].csr
x509 -req -days [days] -in [csr_name].csr -signkey [key_name].key -out [crt_name].crt
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
Step 3: Run SSL Server through OpenSSL
If you have setup the OpenSSL to use as the SSL server, run the SSL server.
s_server -accept [port] -cert [crt_name].crt -key [key_name].key
s_server -accept 443 -cert server.crt -key server.key
Step 4: Setup WIZ5xxSR-RP through WIZnet S2E Configuration Tool for SSL Server Connection
- Select SSL TCP client mode in the Operation mode setting section

Note: If you need certificates to connect to the SSL server, please refer to the 'What If I Need Certificates to Connect to SSL Server' section below.
Step 5: Done
WIZ5xxSR-RP is successfully connected to the SSL server!
What If I Need Certificates to Connect to SSL Server?
You can upload certificates below in the 'Certificate manager' tab of the'WIZnet S2E Configuration Tool'.
- Root CA
- Client Certificate
- Private key
Upload and setup 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.
