OK, for anyone finding this in the future, you 9 need to create your certificates and sign 8 them appropriately. Here are the commands 7 for linux:

//Generate a private key

openssl genrsa -des3 -out server.key 1024

//Generate 6 Certificate signing request

openssl req -new -key server.key -out server.csr

//Sign certificate 5 with private key

openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt

//Remove password requirement 4 (needed for example)

cp server.key server.key.secure
openssl rsa -in server.key.secure -out server.key

//Generate dhparam file

openssl dhparam -out dh512.pem 512

Once 3 you've done that, you need to change the 2 filenames in server.cpp and client.cpp.


context_.use_private_key_file("server.key", boost::asio::ssl::context::pem);



Then 1 it should all work!

Execute the tests again with strace to see 9 which syscall gets the EINVAL, as a bonus you'll 8 get to see the args for the failing call. It's 7 likely part of the security context setup 6 that's failing, unless you have the right 5 files and data from the example:

context_.use_private_key_file("server.pem", boost::asio::ssl::context::pem);

You were 4 getting EPERM because you were trying to bind 3 to a privileged TCP port (one whose value 2 is less than 1024). That's why ./server 10000 does not 1 get EPERM.

When following the answer of @Shootfast an error appered: 'bad 7 SSL configuration: use_certificate_chain_file: ee 6 key too small'

Changing the first line:

openssl genrsa -des3 -out server.key 1024


openssl genrsa -des3 -out server.key 2048

fixed 5 it for me.

After that I got the error: 'bad 4 SSL configuration: use_private_key_file: no 3 start line' the reason and solution to this 2 is explained here: solution (It is more or less 1 the reason for the last command of @Shootfast answer.)
