What is SSL certificate and keystore?

Question

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are protocols that enable clients and servers to communicate over a secure connection. Those security protocols use certificates to validate the identity of the client and server. Certificates are contained in keystores.

What is difference between keystore and certificate?

A keystore contains personal certificates, plus the corresponding private keys that are used to identify the owner of the certificate. For TLS, a personal certificate represents the identity of a TLS endpoint.

What is a keystore SSL?

The SSL keystore holds the identity key for the server and the SSL truststore serves as the repository for trusted certificates. The SSL truststore is used for trusting or authenticating client certificates (for two-way SSL).

What is an SSL certificate used for?

Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser, or a mail server and a mail client (e.g., Outlook).

What is keystore used for?

Keystore is used to store private key and identity certificates that a specific program should present to both parties (server or client) for verification.
