Hi Youssouf,

I think you're looking for mbedtls_mpi_write_file() - just pass NULL as the file argument to write to stdout. You can use the radix argument to print out hex or decimal.

Hi everyone, I think you all are fine.

I am a beginner on mbedtls, and I wanted to set a dhm context. So, at first, I just want to set the value of the prime P, and the generator G. So to that I wrote the function below : [cid:image001.png@01D67AF5.D43FDE60]

To check if it is correctly set, I wanted to print it to see. However, it is not the case. Do you know how to set and print the value ?

Thanks, and have a good day

Best regards, YS
