This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have a website that uses a self signed certificate and some java code that needs to use HttpsUrlConnection to access the site.
I know I need to get the certificate imported into cacerts but I am not sure exactly which certificate I should be importing. Rather, I have an export problem. In firefox, there is a plugin that lets you export the certificate in all sorts of formats:
X.509 Certificate (PEM) .crt extension
X.509 Certificate with chain (PEM) .crt extension
X.509 Certificate (DER) .der extension
X.509 Certificate (PKCS#7) .p7c extension
X.509 Certificate with chain (PKCS#7) .p7c extension
Which one should I choose if I want to then use keytool to import the certificate into cacerts?
