java.security (Java SE 9 & JDK 9 )
An AccessControlContext is used to make system resource access decisions based on the context it encapsulates.
AccessControllerThe AccessController class is used for access control operations and decisions.
AlgorithmParameterGeneratorThe AlgorithmParameterGenerator class is used to generate a
set of
parameters to be used with a certain algorithm.
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.
This class is used as an opaque representation of cryptographic parameters.
AlgorithmParametersSpiThis class defines the Service Provider Interface (SPI)
for the AlgorithmParameters class, which is used to manage
algorithm parameters.
The AllPermission is a permission that implies all other permissions.
AuthProviderThis class defines login and logout methods for a provider.
BasicPermissionThe 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.
CodeSignerThis class encapsulates information about a code signer.
CodeSourceThis class extends the concept of a codebase to encapsulate not only the location (URL) but also the certificate chains that were used to verify signed code originating from that location.
DigestInputStreamA transparent stream that updates the associated message digest using the bits going through the stream.
DigestOutputStreamA transparent stream that updates the associated message digest using the bits going through the stream.
DomainLoadStoreParameterConfiguration data that specifies the keystores in a keystore domain.
DrbgParametersThis class specifies the parameters used by a DRBG (Deterministic Random Bit Generator).
DrbgParameters.InstantiationDRBG parameters for instantiation.
DrbgParameters.NextBytesDRBG parameters for random bits generation.
DrbgParameters.ReseedDRBG parameters for reseed.
GuardedObjectA GuardedObject is an object that is used to protect access to another object.
Identity Deprecated. IdentityScope Deprecated. KeyFactoryKey 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.
This class defines the Service Provider Interface (SPI)
for the KeyFactory class.
This class is a simple holder for a key pair (a public key and a private key).
KeyPairGeneratorThe 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.
Standardized representation for serialized Key objects.
KeyStoreThis class represents a storage facility for cryptographic keys and certificates.
KeyStore.BuilderA description of a to-be-instantiated KeyStore object.
KeyStore.CallbackHandlerProtectionA ProtectionParameter encapsulating a CallbackHandler.
KeyStore.PasswordProtectionA password-based implementation of ProtectionParameter.
A KeyStore entry that holds a PrivateKey
and corresponding certificate chain.
A KeyStore entry that holds a SecretKey.
A KeyStore entry that holds a trusted
Certificate.
This class defines the Service Provider Interface (SPI)
for the KeyStore class.
This MessageDigest class provides applications the functionality of a message digest algorithm, such as SHA-1 or SHA-256.
MessageDigestSpiThis 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.
Abstract class for representing access to a system resource.
PermissionCollectionAbstract class representing a collection of Permission objects.
PermissionsThis class represents a heterogeneous collection of Permissions.
PKCS12AttributeAn attribute associated with a PKCS12 keystore entry.
PolicyA Policy object is responsible for determining whether code executing in the Java runtime environment has permission to perform a security-sensitive operation.
PolicySpiThis class defines the Service Provider Interface (SPI)
for the Policy class.
The ProtectionDomain class encapsulates the characteristics of a domain, which encloses a set of classes whose instances are granted a set of permissions when being executed on behalf of a given set of Principals.
ProviderThis class represents a "provider" for the Java Security API, where a provider implements some or all parts of Java Security.
Provider.ServiceThe description of a security service.
SecureClassLoaderThis 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.
SecureRandomThis class provides a cryptographically strong random number generator (RNG).
SecureRandomSpiThis class defines the Service Provider Interface (SPI)
for the SecureRandom class.
This class centralizes all security properties and common security methods.
SecurityPermissionThis class is for security permissions.
SignatureThe Signature class is used to provide applications the functionality of a digital signature algorithm.
SignatureSpiThis class defines the Service Provider Interface (SPI)
for the Signature class, which is used to provide the
functionality of a digital signature algorithm.
SignedObject is a class for the purpose of creating authentic runtime objects whose integrity cannot be compromised without being detected.
Signer Deprecated. TimestampThis class encapsulates information about a signed timestamp.
UnresolvedPermissionThe UnresolvedPermission class is used to hold Permissions that were "unresolved" when the Policy was initialized.
URIParameterA parameter that contains a URI pointing to data intended for a PolicySpi or ConfigurationSpi implementation.
