| Class | Description | 
|---|---|
| DESedeKeySpec | This class specifies a DES-EDE ("triple-DES") key. | 
| DESKeySpec | This class specifies a DES key. | 
| DHGenParameterSpec | This class specifies the set of parameters used for generating
 Diffie-Hellman (system) parameters for use in Diffie-Hellman key
 agreement. | 
| DHParameterSpec | This class specifies the set of parameters used with the Diffie-Hellman
 algorithm, as specified in PKCS #3: Diffie-Hellman Key-Agreement
 Standard. | 
| DHPrivateKeySpec | This class specifies a Diffie-Hellman private key with its associated
 parameters. | 
| DHPublicKeySpec | This class specifies a Diffie-Hellman public key with its associated
 parameters. | 
| GCMParameterSpec | Specifies the set of parameters required by a  Cipherusing the Galois/Counter Mode (GCM) mode. | 
| IvParameterSpec | This class specifies an initialization vector (IV). | 
| OAEPParameterSpec | This class specifies the set of parameters used with OAEP Padding,
 as defined in the
 PKCS #1
 standard. | 
| PBEKeySpec | A user-chosen password that can be used with password-based encryption
 (PBE). | 
| PBEParameterSpec | This class specifies the set of parameters used with password-based
 encryption (PBE), as defined in the
 PKCS #5
 standard. | 
| PSource | This class specifies the source for encoding input P in OAEP Padding,
 as defined in the
 PKCS #1
 standard. | 
| PSource.PSpecified | This class is used to explicitly specify the value for
 encoding input P in OAEP Padding. | 
| RC2ParameterSpec | This class specifies the parameters used with the
 RC2
 algorithm. | 
| RC5ParameterSpec | This class specifies the parameters used with the
 RC5
 algorithm. | 
| SecretKeySpec | This class specifies a secret key in a provider-independent fashion. | 
A key specification is a transparent representation of the key material that constitutes a key. A key may be specified in an algorithm-specific way, or in an algorithm-independent encoding format (such as ASN.1). This package contains key specifications for Diffie-Hellman public and private keys, as well as key specifications for DES, Triple DES, and PBE secret keys.
An algorithm parameter specification is a transparent representation of the sets of parameters used with an algorithm. This package contains algorithm parameter specifications for parameters used with the Diffie-Hellman, DES, Triple DES, PBE, RC2 and RC5 algorithms.
