Self-signed certificates

If you need self-signed certificate for testing, you can generate it with following commands:

Create Root Key

openssl genrsa -des3 -out rootCA.key 4096

If you want a non password protected key just remove the -des3 option

Create and self sign the Root Certificate

openssl req -x509 -new -nodes -key rootCA.key -sha256 -days 1024 -out ca.pem

Create the server certificate key

openssl genrsa -out privkey.pem

Create the signing request (csr)

openssl req -new -key privkey.pem -out sstp-csr.csr

Create a server certificate

openssl x509 -req -in sstp-csr.csr -CA ca.pem -CAkey rootCA.key -CAcreateserial -out cert.pem -days 365

Convert cert from PEM to CERT format (if it's needed)

openssl x509 -outform der -in your-cert.pem -out your-cert.crt
