certificate

问题 For fun, I recently build a e-signature web app to allow users to add a handwritten signature to PDF (IE signing a TOS agreement). It only took a couple minutes of research to realize my method of just added a written signature image to a PDF probably wouldn't hold up very well in a legal dispute. A cryptographic digital signature is needed to verify the identity of the signee as well as ensure the document has not been altered since signing. It got me wondering how companies like Docusign

问题 I am using ssl.py to connect to a webserver and I would like to verify the server certificate. I have a ROOT_CA which signs an INTERMEDIATE_CA and this finally signs the SERVER_CERTIFICATE. I would like to provide the client only the INTERMEDIATE_CA so it can verify all certificates signed by it. However, it appears that I need to provide the entire certificate chain ROOT_CA->INTERMEDIATE_CA in order for the verification to work. Any insights on this ? Here is the script I am using: import

问题 I am working on a Xamarin Form that need to call httpclient to consume company's internal https REST api. Unfortunately, it return with this error Javax.Net.Ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. How can i resolve this? 回答1: To bypass certification validation you can: In Android Build options choose HttpClient Implementation: AndroidClientHandler SSL/TLS implementation: Default (Native TLS 1.2+) In MainActivity

问题 I try to use X509Certificate2.Verify() function to check if a certificate chain is valid. The Verify function returns false and the ChainElementStatus returns "RevocationStatusUnknown". Is there a way to use the Verify function without the check of the RevocationStatus? The RevocationStatus can't be checked without internet connection? Is there a other function to check the chain and certificates wihtout the RevocationStatus? A dirty solution, is to check if the RevocationStatus is the only

问题 Issue: I have been trying to clone a git repository from a Ubuntu AWS instance, through an http proxy (set in git global config) from an enterprise GitHub server. Cloning from the proxy works, but cloning from the instance (through the proxy) I get the following error: fatal: unable to access 'https://githubserver.company.com/repository.git/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none I have already tried to download the server

问题 For my specific situation, I have to generate a RSA key pair (in my Android application) using the following codes :- KeyPairGenerator generator = KeyPairGenerator.getInstance("RSA/ECB/PKCS1Padding"); generator.initialize(1024,new SecureRandom()); KeyPair keyPair = generator.generateKeyPair); How can I import the keyPair into the Android keyStore ? I have been searching on the Internet for sometimes and did not get how can I create the self-signed certificate for the RSA public key for import

问题 Every time I try to pip install something, this happens: Lucianos-Mac:test luciano$ pip install torch Collecting torch Could not install packages due to an EnvironmentError: Could not find a suitable TLS CA certificate bundle, invalid path: /Users/luciano/Applications/NextGIS/Library/Frameworks/openssl.framework/Resources/ssl/certs/cert.pem The path it references was created when I installed the gdal package from nextgis.com, which I later deleted, so the NextGIS directory does not exist.

问题 I need to get the CN of a client certificate in NGINX to append it to the proxy headers. I already found the following map code for this. map $ssl_client_s_dn $ssl_client_s_dn_cn { default ""; ~/CN=(?<CN>[^/]+) $CN; } But sadly it only returns an empty string for the following $ssl_client_s_dn: CN=testcn,O=Test Organization I tested it with other DNs, too. But the problem is always the same. 回答1: The pattern you use requires the legacy DN, since it assumes the / to separate the RDNs. So

问题 Is it possible to copy a certificate from a smart card to the computer and use it to login to a certain site. On mac, those certificates appear in Keychain and they can be saved to disk, but I'm not sure how to force a site to prompt a dialog screen to choose the certificate. When the smart card is connected, the prompt somehow appears and asks to choose a certificate. 回答1: The smartcard contains a key pair composed by a private key and a public key wrapped into a X509 certificate. It is
