Digital certificate: When there is a key pair, it is also necessary to have a digital certificate to verify the identity of the keys. Typically, the public key of a key pair is embedded in this digital certificate, which also contains additional information such as the owner, validity, etc. of the keys. For example, if an external party wants to verify the integrity of data or validate the identity of the signer (by validating the digital signature), it is necessary for them to have this digital certificate.
Trusted certificates: To establish trust, the digital certificate containing the public key should be signed by a trusted certifying authority (CA). You can generate self-signed certificates for the public key (thereby creating your own certifying authority), or you can get the certificates signed by an external CA. Both types of trusted certificates can be effectively used depending on the sensitivity of the information that is protected by the keys. When the certificate is signed by a reputed CA, all the parties who trust this CA will also trust the certificates signed by them.

The key pair and the CA-signed certificates in a keystore establishes two security functions in your server: The key pair with the digital certificate gives is an indication of identity and the CA-signed certificates certificate provides trust to the identity. Since the public key is used to encrypt information, the keystore containing the corresponding private key should always be protected, as it can decrypt the sensitive information. FurtherFurthermore, the privacy of the private key is important as it represents its own identity and protects the integrity of data. However, the CA-signed digital certificates should be accessible to outside parties that requires require to decrypt and use the information. To facilitate this requirement, the certificates should must be copied to a separate keystore (called a Truststore), which can then be shared with outside parties. Therefore, in a typical setup, you will have one keystore for identity (containing the private key) that is protected, and a separate keystore for trust (containing CA certificates) that is shared with outside parties. |

- Authenticating the communication over Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocols.
- Encrypting sensitive information such as plain text passwords in configuration files.
- Encrypting data such as scripts, configuration files, xmld, xsds etc. into the registry.
- Encrypting/signing in WS-Security.
...
- Maintain a primary keystore for encrypting sensitive data such as admin passwords and certain registry data. By default, the primary keystore is also used for WS-Security and for authenticating tomcat Tomcat level connections.
- Maintain a separate keystore for authenticating the communication over SSL/TLS (tomcat for Tomcat level connections).
- Optionally, you can set up separate keystores with key pairs and certificates for WS-Security.
- A separate keystore (truststore) for the purpose of storing the trusted certificates of public keys in your keystores.

WSO2 products provide the facility to add keystores using the management console Management Console or using an XML configuration, and to import certificates to the keystore using the management consoleManagement Console. The WSO2 keystore management feature provides a UI and an API to add and manage keystores used for WS-Security scenarios. When you apply WS-Security to web Web services using the management consoleManagement Console, you can select a keystore from uploaded keystores for encryption/signing processes. The management console Management Console also allows you to view/delete keystores.
