incorrect cipher_list

[cochoiate]

I am running the hub_server.py on a raspberry pi B (Raspbian GNU/Linux 10 (buster) )
After execute the python hub_server.py I am receiving this error:

**python hub_server.py**
_Traceback (most recent call last):

    raise exception_type(errors)

I have tryied to modify the line: ctx.set_cipher_list('RC4-MD5')
But I am not sure what is the correct cipher that I have to use

the command openssl ciphers -v dumps a lot of different cipher but the one used on the code is missing

Thank you so much for the support!!

Ah, this code is many years old. I don't have a device at hand but I RC4-MD5 is not considered secure these days and I imagine it has probably been removed from your ssl library. I don't have another device on hand to test but you might have luck removing that line and trying again. If the device requires that cipher, you'll need to get an older copy of SSL to build against.
