Package org.keycloak.vault

Class AbstractVaultProvider

java.lang.Object
org.keycloak.vault.AbstractVaultProvider
All Implemented Interfaces:
Provider, VaultProvider
Direct Known Subclasses:
FilesKeystoreVaultProvider, FilesPlainTextVaultProvider
public abstract class AbstractVaultProvider extends Object implements VaultProvider
Abstract class that is meant to be extended by implementations of VaultProvider that want to have support for key resolvers.

This class implements the obtainSecret(String) method by iterating through the configured resolvers in order and, using the final key name provided by each resolver, calls the obtainSecretInternal(String) method that must be implemented by sub-classes. If obtainSecretInternal(String) returns a non-empty secret, it is immediately returned; otherwise the implementation tries again using the next configured resolver until a non-empty secret is obtained or all resolvers have been tried, in which case an empty VaultRawSecret is returned.

Concrete implementations must, in addition to implementing the obtainSecretInternal(String) method, ensure that each constructor calls the AbstractVaultProvider(String, List) constructor from this class so that the realm and list of key resolvers are properly initialized.

    • AbstractVaultProvider

      public AbstractVaultProvider(String realm, List<VaultKeyResolver> configuredResolvers)
      Creates an instance of AbstractVaultProvider with the specified realm and list of key resolvers.
      Parameters:
      realm - the name of the keycloak realm.
      configuredResolvers - a List containing the configured key resolvers.

  • Method Details

    • obtainSecret

      public VaultRawSecret obtainSecret(String vaultSecretId)
      Specified by:
      obtainSecret in interface VaultProvider

    • obtainSecretInternal

      protected abstract VaultRawSecret obtainSecretInternal(String vaultKey)
      Subclasses of AbstractVaultProvider must implement this method. It is meant to be implemented in the same way as the obtainSecret(String) method from the VaultProvider interface, but the specified vault key must be used as is - i.e. implementations should refrain from processing the key again as the format was already defined by one of the configured key resolvers.
      Parameters:
      vaultKey - a String representing the name of the entry that is being fetched from the vault.
      Returns:
      a VaultRawSecret representing the obtained secret. It can be a empty secret if no secret could be obtained using the specified vault key.
