将POST请求发送到使用自签名证书的服务器

Question

I need to send a POST request to a server that uses some levels of security. Unfortunately I don't know much about self signed certificates, I never used or studied it.

In the developer guide of the service it sais that the server uses a "public 1024-bit self signed certificate".

What does it mean? I've to create a certificate or I've to ask for it? If i've to create a certificate, then how I should use it? I'm implementing the client in Java

Answer 1

You need to download the certificate eg with your internet browser. Click through the security information and export the certificate.

Then you need to import it into your local java keystore so that the JVM can find it. For import use the keytool which you find in your jre/bin directory. Documentation for the keytool: http://docs.oracle.com/javase/1.4.2/docs/tooldocs/windows/keytool.html

The default keystore is jre/lib/security/cacerts .

Then you can import the downloaded certificate: jre/bin/keytool -import -keystore jre/lib/security/cacerts -alias mycertificate -file downloads/mycertificate.cer

Hope this helps.

PS If it is self signed or verified its not important at this point. Just you (your client) must trust it.
