x509

问题 Question How can I verify that an X.509 certificate is signed by another certificate using PyOpenSSL or Twisted? I want a client to verify that the received server certificate is the one that signed its client certificate. I've looked through the PyOpenSSL documentation and can't seem to find anything on how to verify a certificate separately from the establishing the SSL connection. I found a reference to OpenSSL.crypto:X509.verify() in twisted.internet._sslverify:PublicKey.verifyCertificate

问题 I have refered the Spring SAML manual to create private key and import public certificate. But I am still facing issues with the encryption/decryption. I have created a JKS file with the following commands as mentioned in the manual which are as follows Command used to Import public certificate of IDP keytool -importcert -alias adfssigning -keystore samlKeystore.jks -file testIdp.cer Command used for Private Key keytool -genkeypair -alias myprivatealias -keypass changeit -keystore

问题 I'm trying some basic examples to request data from the web, however all requests to different hosts result in an SSL error: x509: certificate signed by unknown authority . Note : I'm not behind a proxy and no forms of certificate interception is happening, as using curl or the browser works without problems. The code sample I'm currently working with is: package main import ( "fmt" "net/http" "io/ioutil" "os" ) func main() { response, err := http.Get("https://google.com") if err != nil { fmt

问题 My C# code uses HttpWebRequest to send requests to a web service via HTTP over SSL ( https:// prefixed URLs). The service has it's coolservice.example.com certificate which is signed by certificate authority intermediate certificate which is in turn signed by the trusted root certificate authority certificate. The latter must be in the caller certificate store and marked as "trusted root", otherwise all that SSL trust chain thing makes no sense. However the intermediate certificate may come

问题 If I generate a p12 certificate with openssl as: openssl pkcs12 -export -in myprivatecert.pem -nokeys -out mycert.p12 Even though I ask openssl to not export the private key, why does windows still require the private key password when installing the certificate. I figure I am missing something. 回答1: The password is for the PKCS12 file itself, not for the private key. You can specify a blank password by adding "-password pass:" like this: $ openssl pkcs12 -password pass: -export -in

问题 I'm trying to consume an IBM DataPower 3.7.1.x web service in WCF getting the following error message: Cannot find a token authenticator for the 'System.IdentityModel.Tokens.X509SecurityToken' token type. Tokens of that type cannot be accepted according to current security settings. The HTTP response is coming back as 200 and I can see the correct SOAP response while debugging it in Fiddler. However, the WCF clients doesn't seem to know how to process the BinarySecurityToken element in the

问题 I am trying to validate an X.509 certificate using C# and .NetCF. I have the CA certificate, and if I understand correctly, I need to use the public key from this CA certificate to decrypt the signature of the untrusted certificate. This should give me the computed hash value of the untrusted certificate. I should then compute the hash of the certificate myself and make sure the two values match. I've been playing with this for a few days and I'm not getting very far. I've been using the

问题 I need to verify the domain of an X509 certificate using C-land OpenSSL. My understanding is that the library doesn't do this for me, and that I have to implement roughly the following algorithm: If the dnsName field of the subjectAlternativeName extension is present, set name to that value. Otherwise, set name to the CN field of the subject. Compare name against the requested hostname, allowing each asterisk to match [A-Za-z0-9_]+, but not 'dot' (.). It seems to me that there should be

问题 I have a public key in the following format -----BEGIN PUBLIC KEY----- xxxxxxxx -----END PUBLIC KEY----- I need to convert this into the following format -----BEGIN RSA PUBLIC KEY----- xxxxxxxxx -----END RSA PUBLIC KEY----- Basically, the issue is that I am working with a third party library which is written in Java. The third party library uses Java class "RSAPublicKeySpec" to generate an instance of type RSAPublicKey from a String. The String that I am supplying to this third party library

问题 Apple released their New Generation WSDL on the 15 of August this year (2015) and the big change was that every call to the WSDL had to be validated with a certificate file. I've done the process to get the certificate from Apple, and I've whitelisted our server IP, and I've even verified that I can get access to the service endpoint from our server by coding a simple interface using HttpWebRequest where I easily can attach the certificate using webRequest.ClientCertificates.Add(), so I know
