com.ibm.portal.portlet.service.credentialvault.spi
Interface EncryptionExit

public interface EncryptionExit

Encryption exit interface for encrypting and decrypting passwords stored in the default vault of the portal.

The credential vault supports an encryption exit for the default vault adapter. To use custom encryption and decryption mechanisms, implement this interface. To register a custom implementation, perform the following steps:

• Deploy your implementation to the portal (for example, place the Java archive file in the directory PortalServer_root/shared/app/).
• Create a text file with the name defaultvault.
• Edit the text file and use the encryptionExit property to specify the fully qualified class name of your implementation, for example: encryptionExit=com.yourcompany.credentialvault.YourEncryptionExit
• Place the text file in the directory PortalServer_root/shared/app/.
• Restart the portal.

The implementation of this interface is optional. The portal uses a default implementation if nothing else is configured.

Since:

5.1.0.1

Note:

This interface is designed to be implemented by clients.
