Today we discuss keys and certificates. They are used to secure data by using the public key to encrypt and the private key to decrypt. The certificate is used as a stamp of authority. Certificates can include the public key. The certificate then becomes usable to secure the ends of a channel such as https.
Keys and certificates are therefore as important to keep safe as passwords. These keys and certificates can be cut as many times as necessary and for different scopes and purposes. When the number of such secrets increases, they have to be managed in a vault or an secret management system. There are external key managers available for this purpose.
let us take a look at their formats. The choice of encryption algorithm provided different content and format for the keys and certificates. over time, different versions became recognized as standards even for the same encryption parameters. Finally, users began requesting them to be bundled as keystores and truststores.
Keystores is a combination of key and certificate. It is made available in the form of a file with pfx extension or p12 extension. Many applications prefer accepting a keystore rather than keys and certificates separately. The key Store is essentially a header and a collection of bags. one bag may contain the private key while another may contain the certificate. There can be more than one certificates in the bag.
The truststores is merely a collection of certificates to be trusted. It could include a certificate chain if the certificates are signed.
The generation of these bundles is specified in the RFC and performed with command line tools such as openssl and keytool. Not all languages have libraries to generate these bundles since it is generally not a logic to be included in an application. if the keys and certificates are cut once, they don't need to be modified again.
Common issues encountered with generating these bundles is mentioned here: https://github.com/ravibeta/go-pkcs12/commit/db4cf640b9698ad37d9d170a9a75bf49d7425b71 line 427
