Classes in java.security used by java.security

Class and Description
DigestException This is the generic Message Digest exception.
GeneralSecurityException The GeneralSecurityException class is a generic security exception class that provides type safety for all the security-related exception classes that extend from it.
InvalidAlgorithmParameterException This is the exception for invalid or inappropriate algorithm parameters.
InvalidKeyException This is the exception for invalid Keys (invalid encoding, wrong length, uninitialized, etc).
Key The Key interface is the top-level interface for all keys.
KeyException This is the basic key exception.
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.
KeyStore This class represents a storage facility for cryptographic keys and certificates.
KeyStoreException This is the generic KeyStore exception.
MessageDigest This MessageDigest class provides applications the functionality of a message digest algorithm, such as SHA-1 or SHA-256.
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.
NoSuchAlgorithmException This exception is thrown when a particular cryptographic algorithm is requested but is not available in the environment.
NoSuchProviderException This exception is thrown when a particular security provider is requested but is not available in the environment.
PrivateKey A private key.
PublicKey A public key.
SecureRandom This class provides a cryptographically strong random number generator (RNG).
Signature The Signature class is used to provide applications the functionality of a digital signature algorithm.
SignatureException This is the generic Signature exception.
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.
UnrecoverableEntryException This exception is thrown if an entry in the keystore cannot be recovered.
UnrecoverableKeyException This exception is thrown if a key in the keystore cannot be recovered.
