Class ConfidentialStore

java.lang.Object

jenkins.security.ConfidentialStore

Direct Known Subclasses:

DefaultConfidentialStore

public abstract class ConfidentialStore
extends Object

The actual storage for the data held by ConfidentialKeys, and the holder of the master secret.

This class is only relevant for the implementers of ConfidentialKeys. Most plugin code should interact with ConfidentialKeys.

OEM distributions of Jenkins can provide a custom ConfidentialStore implementation by writing a subclass, mark it with MetaInfServices annotation, package it as a Jenkins module, and bundling it with the war file. This doesn't use Extension because some plugins have been found to use Secret before we get to InitMilestone.PLUGINS_PREPARED, and therefore Extensions aren't loaded yet. (Similarly, it's conceivable that some future core code might need this early on during the boot sequence.)

Modifier and Type	Method and Description
static ConfidentialStore	get() Retrieves the currently active singleton instance of ConfidentialStore.
protected abstract byte[]	load(ConfidentialKey key) Reverse operation of store(ConfidentialKey, byte[])
abstract byte[]	randomBytes(int size) Works like SecureRandom.nextBytes(byte[]).
protected abstract void	store(ConfidentialKey key, byte[] payload) Persists the payload of ConfidentialKey to a persisted storage (such as disk.) The expectation is that the persisted form is secure.

Method Detail

store

protected abstract void store(ConfidentialKey key,
                              byte[] payload)
                       throws IOException

Persists the payload of ConfidentialKey to a persisted storage (such as disk.) The expectation is that the persisted form is secure.

Throws:

IOException

load

@CheckForNull
protected abstract byte[] load(ConfidentialKey key)
                                      throws IOException

Reverse operation of store(ConfidentialKey, byte[])

Returns:

null the data has not been previously persisted, or if the data was tampered.

Throws:

IOException

randomBytes

public abstract byte[] randomBytes(int size)

Works like SecureRandom.nextBytes(byte[]). This enables implementations to consult other entropy sources, if it's available.

get

@Nonnull
public static ConfidentialStore get()

Retrieves the currently active singleton instance of ConfidentialStore.
