OpenSSL Sample Code
These samples have been written for OpenSSL with bugfixes applied.
UDP
-
This sample includes a multi-threaded echo server and client sending messages over an UDP connection encrypted with DTLS.
-
This sample includes a multi-threaded character generator server and client sending as many messages as possible to each other over an UDP connection encrypted with DTLS for a given time. Statistics how many messages have been sent and received and how many got lost are printed at the end.
-
This sample includes a multi-threaded discard server and client sending messages over an UDP connection encrypted with DTLS.
SCTP
-
This sample includes a multi-threaded echo server and client sending messages over an SCTP connection encrypted with DTLS.
-
This sample includes a multi-threaded character generator server and client sending as many messages as possible to each other over an SCTP connection encrypted with DTLS for a given time. Statistics how many messages have been sent and received are printed at the end.
-
This sample includes a multi-threaded discard server and client sending messages over an SCTP connection encrypted with DTLS.
OpenSSL Certificates
The following commands create signed certificates for client and server of the samples above.
touch ca-db-index
echo 01 > ca-db-serial
# Certificate Authority
openssl req -nodes -x509 -newkey rsa:512 -days 365 -keyout ca-key.pem -out ca-cert.pem
# Server Certificate
openssl req -nodes -new -newkey rsa:512 -keyout server-key.pem -out server.csr
# Sign Server Certificate
openssl ca -config ca.conf -days 365 -in server.csr -out server-cert.pem
# Client Certificate
openssl req -nodes -new -newkey rsa:512 -keyout client-key.pem -out client.csr
# Sign Client Certificate
openssl ca -config ca.conf -days 365 -in client.csr -out client-cert.pem
You can create your own ca.conf file or use a minimal sample.
