Migration Strategy
- ESAPI 2.1
- Create new package org.owasp.esapi.core
- Create new set of Interfaces in new package with each extending it's org.owasp.esapi counterpart
- Deprecate methods in org.owasp.esapi Interfaces
- ESAPI 2.5
- Remove deprecated methods that were deprecated at or before ESAPI 2.0
- Introduce new ServiceLocator API
- ESAPI 3.0
- Seperate Core API into it's own artifact/project called ESAPI-Core
- Create new set of artifacts as outlined in ESAPI_Project_Structure
- Introduce Core API Testing Suite
Core API
AccessController
The AccessController is responsible for determining if the currently logged in user has access to a given resource. The resource can be anything that implements the Resource Interface.
Changes from ESAPI 2.0
- Removed deprecated methods
- Added Generic Stereotypes to the Key and Context parameters)
StereoTypes
| Parameter | Description |
|---|---|
| R | A class that implements the Resource Interface and represents the Resource the user is requesting access to |
| Context | Any object that represents the current context of the Authorization request - this is generally a Key-Value map |
Methods
<R extends Resource,Context> void assertAuthorized(Resource resource, Context context) throws AccessDeniedException
Assert that the currently logged in user can access the given Resource with the given Context parameters
Parameters
| Parameter | Default Value | Description |
|---|---|---|
| resource | The resource that the user is attempting to access | |
| context | The context of the request. This could be any type of object - for instance if requesting access to data, the context may be the resource identifier for the identified resource. |
Exceptions
| Exception | Description |
|---|---|
| AccessDeniedException | If the assertion evaluates to false, an AccessControlException will be thrown with contextual information as to the reason for the failure |
<R extends Resource,Context> boolean isAuthorized(Resource resource, Context context)
Determine if the given resource is accessible by the currently logged in User
Parameters
| Parameter | Default Value | Description |
|---|---|---|
| resource | The resource that the user is attempting to access | |
| context | The context of the request. This could be any type of object - for instance if requesting access to data, the context may be the resource identifier for the identified resource. |
Return
Returns true if the resource is accessible to the currently logged in user and false if it is not.
AccessReferenceMap<Key>
<Type> Key addDirectReference(Type direct)
<Type> Type getDirectReference(Key key)
<Type> Key getIndirectReference(Type directReference)
<Type> Key removeDirectReference(Type directReference)

String sign(String data) throws EncryptionException
String unseal(String sealedData) throws EncryptionException
void verifySeal(String sealedData) throws DataIntegrityException

String getRandomUUID()
Integer getRandomInteger(Integer min, Integer max)
Long getRandomLong(Long min, Long max)
