Creating a CSR file on the ESP 8266 #336

Open pcMan101 opened 7 years ago

pcMan101 commented 7 years ago

Hi,

do you know any example in which a CSR file is created using the mbedTLS library on the ESP 8266? Although I've looked for it a long time I didn't found a working example.

Thank you.

Are you 100% sure you need a CSR? a self signed certificate is often a better bet for an esp8266, in which case you can use openssl to generate one as in the comments in examples/tls_server/cert.c It depends of course, what's your intended use?

Thank you! But I want my ESP to generate a CSR, send it to a server which gives back a Client Certificate to my ESP.

Ah ok, if no one else has an example you could try using the method on the mbed website: https://tls.mbed.org/kb/how-to/generate-a-certificate-request-csr The source for both programs mentioned is in the extras/mbedtls/ directory so it may be possible to lift the required functions from them and get it working.
