Accepting a certificate for HTTPs on Android.The following main steps are required to achieve a secured connection from Certification Authorities which are not considered as trusted by the android platform.As requested by many users, Ive mirrored the most important parts from my blog article here Grab all required certificates root and any intermediate CAsCreate a keystore with keytool and the Bouncy.Castle provider and import the certs.Load the keystore in your android app and use it for the secured connections I recommend to use the Apache Http.Client instead of the standard java.Https. URLConnection easier to understand, more performantGrab the certs.You have to obtain all certificates that build a chain from the endpoint certificate the whole way up to the Root CA.This means, any if present Intermediate CA certs and also the Root CA cert.Need an API to convert files Use our comprehensive documentation to get up running in minutes convert Documents, Videos, Images, Audio, eBooks more.You dont need to obtain the endpoint certificate.Create the keystore.Download the Bouncy.Castle Provider and store it to a known location.A hands on lab about building reactive microservice systems with Vert.Java 2 Platform Standard Edition Development Kit 5.Update 22 JDK 5. 0 Update 22 Microsoft Windows, Linux, and Solaris Operating Systems.Fix configuration of Eclipse projects, broken by introduction of SafeForkJoinWorkerThreadFactory helper class.This class cannot be built with Java 6.Also ensure that you can invoke the keytool command usually located under the bin folder of your JRE installation.Now import the obtained certs dont import the endpoint cert into a Bouncy.Castle formatted keystore.I didnt tested it, but I think the order of importing the certificates is important.This means, import the lowermost Intermediate CA certificate first and then all the way up to the Root CA certificate.With the following command a new keystore if not already present with the password mysecret will be created and the Intermediate CA certificate will be imported.I also defined the Bouncy.Castle provider, where it can be found on my file system and the keystore format.Execute this command for each certificate in the chain.Intermediate.
