In various scenarios, you must import your third-party certificates and private keys
into your instance’s keystore. A keystore can store multiple entries, each of which can be
of type PrivateKeyEntry or of type
TrustedCertificateEntry. This is similar to the terminology used by
java.security.KeyStore.
Private Key Entry
Each PrivateKeyEntry in an instance’s keystore holds the private key
and its corresponding public key. This set of keys is used to communicate with
external web services and to transfer files from your instance’s WebDAV client to
external WebDAV servers. Custom code that uses a KeyRef or
CertificateRef parameter use these keys when encrypting or
decrypting data, for example, custom code used to encrypt or decrypt data.
Trusted Certificate Entry
Each TrustedCertificateEntry in an instance’s keystore holds the
public key certificates that validate server certificates when establishing outbound
SSL connections. By default, B2C Commerce recognizes only the root CAs that ship
with Oracle's Java platform. However, you can import a CA certificate to the
instance’s keystore.
Certificate Rotation
The rotation of certificates, and their corresponding private keys, is important for a variety of reasons, including dealing with expired certificates, revoked certificates, or private key compromise. If a certificate expires, certificate rotation is required to continue using the certificate to secure your communications. If a certificate is revoked or a private key is compromised, certificate rotation is required to prevent an attacker from abusing the certificate.
If you use certificate rotation to protect data at rest using custom code, then the situation is more complex because you must deal with data that was encrypted with the previous key.
Follow these steps to handle this situation.
- Generate a new key.
- Identify the data encrypted with the old key.
- Decrypt the data with the old key.
- Re-encrypt the data with the new key.
- Delete the old key and the data encrypted with the old key.
Retain the old key in case data that was encrypted with the old key wasn’t identified in this process.
