Interface CredentialVaultService

public interface CredentialVaultService

The Credential Vault service interface allows management of credentials

Each credential and its optional metadata are stored in a credential entry. Credentials are stored in encrypted format, while its metadata (name value pairs of String type) are stored in plaintext.

There are 3 types of credential entry:

• RESOURCE_TYPE: credential entry only accessiable to a particular resource instance of a logined user, which create the credential entry.
• USER_TYPE: credential entry is accessiable to all the resource instances of a logined user.
• SYSTEM_TYPE: credential entry is accessiable to all resource instances of all logined users.

Credential entries also have 3 different visibilities:

• Webapp scoped credential entries are not visible to a different webapp of the same enterprise application.
  e.g., a USER_TYPE credential entry named "foo" for user "bar" in different portal webapps will have different entries, probably storing different credentials.
• Enterprise application scoped credential entries are not visible to a different enterprise application in the same domain.
• Domain scoped credential entries are global entries, which visible to all applications within the domain.

A concrete CredentialVaultService implementation may support one or more Credential.CredentialType. and manages storing and retrival credential entries to/from its persistence layer.

The default CredentialVaultService implementation currently support USERNAME_PASSWORD_CREDENTIAL. It can be accessed via service factory:

CredentialVaultService cvs = com.bea.wlp.services.Services.getService(com.bea.p13n.security.management.credentials.CredentialVaultService.class)

type - predefined value in CredentialEntry.EntryType

description - optional description of the credential entry

requestResource - the resource requesting a credential entry

Returns

newly credential entry

Throws

AlreadyExistsException - If the entry already exists in vault

CredentialAccessException - If user doesn't have privilidge to create the credential entry

CredentialVaultException - persistenct error during credential entry creation

IllegalArgumentException - if entryName is null or empty

                                     throws CredentialVaultException

Retrieve an entry from credential vault For USER_TYPE or SYSTEM_TYPE entries, if there are more than one entries with same name but in different scope, the one with closest scope to requesting resource will be retrieved.

Parameters

type - predefined value in CredentialEntry.EntryType

requestResource - the resource requesting a credential entry

Returns

a credential entry with specified characters or null if not exists

Throws

CredentialVaultException - Error during credential entry retrieval

listAccessibleCredentialEntries

Iterator<? extends CredentialEntry> listAccessibleCredentialEntries(ResourceKey requestResource)
                                                                    throws CredentialVaultException

Retrieve all credential entries visible to requesting resource and requester, including RESOURCE_TYPE entries bound to request resource, USER_TYPE entries created by requester, and SYSTEM_TYPE entries.

Parameters

requestResource - the resource requesting credential entries

Returns

an iterator to a collection of visible credential entries

Throws

CredentialVaultException - Error during credential entries retrieval

removeCredentialEntry

boolean removeCredentialEntry(String entryName,
                              CredentialEntry.EntryType type,
