This package provides the classes and interfaces for cryptographic applications implementing algorithms for encryption, decryption, or key agreement.
Stream ciphers are supported as well as asymmetric, symmetric and block ciphers. Cipher implementations from different providers can be integrated using the SPI (Service Provider Interface) abstract classes. With class Javax.Crypto.SealedObject a programmer can secure an object by encrypting it with a cipher.
Authentication may be based on MAC (Message Authentication Code) such as HMAC (Hash MAC, i.e. with a SHA-1 hash function).
Type | Reason |
---|---|
AEADBadTagException | Thrown by a Javax.Crypto.Cipher that is using an Authenticated Encryption with Additional Data (AEAD) mode such as Galois/Counter Mode (GCM) and the tag failed verification. |
BadPaddingException | The exception that is thrown when a padding mechanism is expected for the input data, but the input data does not have the proper padding bytes. |
Cipher | This class provides access to implementations of cryptographic ciphers for encryption and decryption. |
CipherInputStream | This class wraps an InputStream and a cipher so that read() methods return data that are read from the underlying InputStream and processed by the cipher. |
CipherMode | Enumerates values returned by several types and taken as a parameter of several methods of Javax.Crypto.Cipher. |
CipherOutputStream | This class wraps an output stream and a cipher so that write methods send the data through the cipher before writing them to the underlying output stream. |
CipherSpi | This class defines the Service Provider Interface (SPI) for cryptographic ciphers. |
EncryptedPrivateKeyInfo | This class implements the EncryptedPrivateKeyInfo ASN.1 type as specified in . |
ExemptionMechanism | This class implements the functionality of an exemption mechanism such as key recovery, key weakening, or key escrow. |
ExemptionMechanismException | This is the base class for ExemptionMechanismException. |
ExemptionMechanismSpi | The Service Provider Interface (SPI) definition for the ExemptionMechanism class. |
IllegalBlockSizeException | The exception, that is thrown when the data length provided to a block cipher does not match the block size of the cipher. |
ISecretKey | A cryptographic secret (symmetric) key. |
KeyAgreement | This class provides the functionality for a key exchange protocol. |
KeyAgreementSpi | The Service Provider Interface (SPI) definition for the KeyAgreement class. |
KeyGenerator | This class provides the public API for generating symmetric cryptographic keys. |
KeyGeneratorSpi | The Service Provider Interface (SPI) definition for the KeyGenerator class. |
KeyType | Enumerates values returned by several types and taken as a parameter of the Javax.Crypto.Cipher.Unwrap member. |
Mac | This class provides the public API for Message Authentication Code (MAC) algorithms. |
MacSpi | The Service-Provider Interface (SPI) definition for the Mac class. |
NoSuchPaddingException | The exception that is thrown when the requested padding mechanism is not supported. |
NullCipher | This class provides an identity cipher that does not transform the input data in any way. |
SealedObject | A SealedObject is a wrapper around a serializable object instance and encrypts it using a cryptographic cipher. |
SecretKey | A cryptographic secret (symmetric) key. |
SecretKeyConsts | Documentation for this section has not yet been entered. |
SecretKeyFactory | The public API for SecretKeyFactory implementations. |
SecretKeyFactorySpi | The Service Provider Interface (SPI) definition for the SecretKeyFactory class. |
ShortBufferException | The exception that is thrown when the result of an operation is attempted to store in a user provided buffer that is too small. |
