My (very limited) understanding is that when you visit an https site, the server sends a certificate to the client (the browser) and the browser gets the certificate's issuer information from that certificate, then uses that to contact the issuerer, and somehow compares certificates for validity.

2015年11月5日 · True: causes the certificate to validated against the library's own trusted certificate authorities (Note: you can see which Root Certificates Requests uses via the Certifi library, a trust database of RCs extracted from Requests: Certifi - Trust Database for Humans). False: bypasses certificate validation completely.

2023年4月24日 · Second is to add the self-signed certificate to Git as a trusted certificate. Disable SSL Verification. The quickest and easiest way is to globally disable SSL verification on Git to clone the repository. But after cloning, you will immediately enable it again, otherwise Git won't verify certificate signatures for other repositories.

2019年1月28日 · This option determines whether curl verifies the authenticity of the peer's certificate. A value of 1 means curl verifies; 0 (zero) means it doesn't. [...] Curl verifies whether the certificate is authentic, i.e. that you can trust that the server is who the certificate says it is. –

2014年1月17日 · Long answer. The basic reason is that your computer doesn't trust the certificate authority that signed the certificate used on the GitLab server.

import warnings import contextlib import requests from urllib3.exceptions import InsecureRequestWarning old_merge_environment_settings = requests.Session.merge_environment_settings @contextlib.contextmanager def no_ssl_verification(): opened_adapters = set() def merge_environment_settings(self, url, …

If you have e.g. cachain.pem containing the whole CA chain starting with the root certificate and e.g. mycert.pem containing the certificate to check then. openssl verify -CAfile cachain.pem -untrusted cachain.pem mycert.pem equivalent to (as …

2012年7月18日 · In Windows you would put the certificate into the local machines certificate store. Run mmc.exe then add/remove snapin>certificates>local computer. Put any end entity certificates into the Personal store then, intermediate certs into the Intermedate folder, etc, etc. –

OpenSSL then scans over each trusted certificate on the chain looking for SSLv3 extensions that specify the purpose of the trusted certificate. If the trusted certificate has the right "trust" attributes for the "purpose" of the verification operation (or has the anyExtendedKeyUsage attribute) the chain is trusted. (Forgive the hand-wave on ...

Just an FYI, we were connecting to a 3rd party server temporarily that had certificate issues so we had to use IO.copy_stream( open( url, { ssl_verify_mode: OpenSSL::SSL::VERIFY_NONE } ), download_path ) to just disable the SSL verification. In our case, security wasn't an issue, the server was out of our control and it was a temporary solution.
