How do I add a certificate to RestTemplate?
To configure Spring RestTemplate to use a client certification in a HTTPS connection, you can follow these steps:
- KeyStore clientStore = KeyStore.
- Defines a SSLContextBuilder to custom and build the SSL context to be used with the RestTemplate.
- Defines a SSLConnectionSocketFactory with the SSLContextBuilder from step 2.

How do I use certificates for authentication in Java?

- Receive 2 certificate: my client root certificate clientId.crt and bank root certificate: bank.crt.

How does authentication with certificates work?
Certificate based authentication allows users to securely access a server by exchanging a digital certificate instead of a username and password. Because the certificate is signed, it is only possible to connect to the real server, and centrally manage the certificates using the CA for rotation or revocation.
How do x509 certificates work?
509 certificate is that it is architected using a key pair consisting of a related public key and a private key. Applied to cryptography, the public and private key pair is used to encrypt and decrypt a message, ensuring both the identity of the sender and the security of the message itself.
What is the difference between self-signed certificate and CA certificate?
The primary operational difference between a self-signed certificate and a CA certificate is that with self-signed, a browser will generally give some type of error, warning that the certificate is not issued by a CA. Generally, this warning should occur only once per browsing session.
What does a self signed certificate do?
In cryptography and computer security, a self-signed certificate is a security certificate that is not signed by a certificate authority (CA). For instance, when a website owner uses a self-signed certificate to provide HTTPS services, people who visit that website will see a warning in their browser.
Why does one need to use a self signed certificate instead of using a Certificate Authority signed certificate which one is more secure?
While Self-Signed certificates do offer encryption, they offer no authentication and that’s going to be a problem with the browsers. Trusted CA Signed SSL Certificates, on the other hand, do offer authentication and that, in turn, allows them to avoid those pesky browser warnings and work as an SSL Certificate should.
Can you renew a self signed certificate?

Scenario: for example, you have a certificate called apache. crt which has been expired and you want to renew it for the next 365 days.
How do you increase the validity of a self signed certificate?
Export the private key (with keytool & openssl or through the keystore-explorer UI, which is much simpler) Make a certificate signing request (with keytool or through the keystore-explorer UI) Sign the request with the private key (i.e. self-signed) Import the certificate in the store to replace the old (expired) one.
