Programmatically add a self-signed certificate to your keystore/truststore


Programmatically add a self-signed certificate to your keystore/truststore

around this issue I saw this question (and others) where it is explained how to add a (self-signed) certificate to your keystore/cacerts manually by using the commandline. When doing this, you can set up a secured connection with a server without a signed certificate, if you were given the certificate (.cert file). This is can be useful for testing purposes. , Rather simple:
code :
InputStream input = ...;
CertificateFactory factory = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate) factory.generateCertificate(input);
KeyStore keystore = ...;
keystore.setCertificateEntry(alias, cert);

Keeping the same private key on your root CA allows for all certificates to continue to validate successfully against the new root; all that's required of you is to trust the new root.
