Package com.ibm.security12.java.security

Interface Summary
Guard This interface represents a guard, which is an object that is used to protect access to another object.
PrivilegedAction A computation to be performed with privileges enabled.
PrivilegedExceptionAction A computation to be performed with privileges enabled, that throws one or more checked exceptions.
 

Class Summary
AccessControlContext An AccessControlContext is used to make system resource access decisions based on the context it encapsulates.
AccessController The AccessController class is used for three purposes: to decide whether an access to a critical system resource is to be allowed or denied, based on the security policy currently in effect, to mark code as being "privileged", thus affecting subsequent access determinations, and to obtain a "snapshot" of the current calling context so access-control decisions from a different context can be made with respect to the saved context.
AlgorithmParameterGenerator The AlgorithmParameterGenerator class is used to generate a set of parameters to be used with a certain algorithm.
AlgorithmParameterGeneratorSpi This class defines the Service Provider Interface (SPI) for the AlgorithmParameterGenerator class, which is used to generate a set of parameters to be used with a certain algorithm.
AlgorithmParameters This class is used as an opaque representation of cryptographic parameters.
AlgorithmParametersSpi This class defines the Service Provider Interface (SPI) for the AlgorithmParameters class, which is used to manage algorithm parameters.
AllPermission The AllPermission is a permission that implies all other permissions.
BasicPermission The BasicPermission class extends the Permission class, and can be used as the base class for permissions that want to follow the same naming convention as BasicPermission.
CertificateFactory This class defines the functionality of a certificate factory, which is used to generate certificate and certificate revocation list (CRL) objects from their encodings.
CodeSource This class extends the concept of a codebase to encapsulate not only the location (URL) but also the certificate(s) that were used to verify signed code originating from that location.
DigestInputStream A transparent stream that updates the associated message digest using the bits going through the stream.
DigestOutputStream A transparent stream that updates the associated message digest using the bits going through the stream.
GuardedObject A GuardedObject is an object that is used to protect access to another object.
Identity Deprecated. This class is no longer used.
IdentityScope Deprecated. This class is no longer used.
KeyFactory Key factories are used to convert keys (opaque cryptographic keys of type Key) into key specifications (transparent representations of the underlying key material), and vice versa.
KeyFactorySpi This class defines the Service Provider Interface (SPI) for the KeyFactory class.
KeyPair This class is a simple holder for a key pair (a public key and a private key).
KeyPairGenerator The KeyPairGenerator class is used to generate pairs of public and private keys.
KeyPairGeneratorSpi This class defines the Service Provider Interface (SPI) for the KeyPairGenerator class, which is used to generate pairs of public and private keys.
KeyStore This class represents an in-memory collection of keys and certificates.
KeyStoreSpi This class defines the Service Provider Interface (SPI) for the KeyStore class.
MessageDigest This MessageDigest class provides applications the functionality of a message digest algorithm, such as MD5 or SHA.
MessageDigestSpi This class defines the Service Provider Interface (SPI) for the MessageDigest class, which provides the functionality of a message digest algorithm, such as MD5 or SHA.
Permission Abstract class for representing access to a system resource.
PermissionCollection Abstract class representing a collection of Permission objects.
Permissions This class represents a heterogeneous collection of Permissions.
Policy This is an abstract class for representing the system security policy for a Java application environment (specifying which permissions are available for code from various sources).
ProtectionDomain This ProtectionDomain class encapulates the characteristics of a domain, which encloses a set of classes whose instances are granted the same set of permissions.
ProtectionDomainStore  
Provider This class represents a "provider" for the Java Security API, where a provider implements some or all parts of Java Security, including: Algorithms (such as DSA, RSA, MD5 or SHA-1).
SecureClassLoader This class extends ClassLoader with additional support for defining classes with an associated code source and permissions which are retrieved by the system policy by default.
SecureRandom This class provides a cryptographically strong pseudo-random number generator (PRNG).
SecureRandomSpi This class defines the Service Provider Interface (SPI) for the SecureRandom class.
Security This class centralizes all security properties and common security methods.
SecurityPermission This class is for security permissions.
Signature This Signature class is used to provide applications the functionality of a digital signature algorithm.
SignatureSpi This class defines the Service Provider Interface (SPI) for the Signature class, which is used to provide the functionality of a digital signature algorithm.
SignedObject SignedObject is a class for the purpose of creating authentic runtime objects whose integrity cannot be compromised without being detected.
Signer This class is used to represent an Identity that can also digitally sign data.
ThreadProtectionNative  
UnresolvedPermission The UnresolvedPermission class is used to hold Permissions that were "unresolved" when the Policy was initialized.
 

Exception Summary
AccessControlException This exception is thrown by the AccessController to indicate that a requested access (to a critical system resource such as the file system or the network) is denied.
GeneralSecurityException This is the general security exception class, which serves to group all the exception classes of the java.security package that extend from it.
InvalidAlgorithmParameterException This is the exception for invalid or inappropriate algorithm parameters.
KeyStoreException This is the generic KeyStore exception.
PrivilegedActionException This exception is thrown by doPrivileged(PrivilegedExceptionAction) and doPrivileged(PrivilegedExceptionAction, AccessControlContext context) to indicate that the action being performed threw a checked exception.
UnrecoverableKeyException This exception is thrown if a key in the key store cannot be recovered.
