Python requests self signed certificate
If the URL uses a self signed certificate, this fails with Show
I know that I can pass
However, what I would like to do is point requests to a copy of the public key on disk and tell it to trust that certificate.

Then set the requests REQUESTS_CA_BUNDLE var to that file in my ./.bash_profile.

Jordan MJordan M 1532 silver badges6 bronze badges All of the answers to this question point to the same path: get the PEM file, but they don't tell you how to get it from the website itself. Getting the PEM file from the website itself is a valid option if you trust the site, such as on an internal corporate server. If you trust the site, why should you do this? You should do this because it helps protect yourself and others from inadvertently re-using your code on a site that isn't safe. Here is how you can get the PEM file.

AlexAlex 964 bronze badges I know it is an old thread. However, I run into this issue recently. My python requests code does not accept the self-signed certificate but curl does. It turns out python requests are very strict on the self-signed certificate. It needs to be a root CA certificate. In other words,

YufengYufeng 211 silver badge1 bronze badge How do I check if a python certificate is selfTo verify this the key type or to check an unknown key type in python, you can use the isinstance method passing in the key and the algorithm. See below for an example on how to determine the key type of a public key or a private key in python. public_key = cert. public_key() if isinstance(public_key, rsa.
How do I disable security certificate checks for request in Python?Method 1: Passing verify=False to request method
Along with the URL also pass the verify=False parameter to the method in order to disable the security checks.
Does Python requests use HTTPS?Requests verifies SSL certificates for HTTPS requests, just like a web browser. SSL Certificates are small data files that digitally bind a cryptographic key to an organization's details.
Does request use certifi?Requests uses certificates from the package certifi.
