Update self-signed certificate (should contain 2048 bits key length)

[ebussieres]

Default self-signed certificate has a key of only 1024 bits

openssl rsa -in key.pem -text -noout | grep "Private-Key"
RSA Private-Key: (1024 bit, 2 primes)

While trying to run it, I got an error telling me that the key is too small. I think that certificates should use at least 2048 bits which is now the default and required value.

Is it possible to regenerate it ? Thanks

do you solve this error?

[ebussieres]

Well I generated a self signed certificate and I use it in command line instead of using the default one

stubby -d endpoints.yml -l localhost -w -c src/mock/tls/cert.pem -k src/mock/tls/key.pem
