Description

Interface Summary

EntropyHarvester	Allow various components with some entropy to feed that entropy back into some PRNG.
TagSetHandle	An opaque handle to a TagSet returned by the SessionKeyManager, so that OCMOSJ can report that the tags were later acked, or not.

Class Summary

AESEngine	Dummy wrapper for AES cipher operation.
CryptixAESEngine	Wrapper for AES cypher operation using Cryptix's Rijndael implementation.
CryptixAESKeyCache	Cache the objects used in CryptixRijndael_Algorithm.makeKey to reduce memory churn.
CryptixAESKeyCache.KeyCacheEntry	all the data alloc'ed in a makeKey call
CryptixRijndael_Algorithm	Rijndael --pronounced Reindaal-- is a variable block-size (128-, 192- and 256-bit), variable key-size (128-, 192- and 256-bit) symmetric cipher.
CryptoConstants	Prime for ElGamal from http://tools.ietf.org/html/rfc3526 Primes for DSA: Generated by TheCrypto http://article.gmane.org/gmane.comp.security.invisiblenet.iip.devel/343
DSAEngine	Sign and verify using DSA-SHA1.
DummyDSAEngine	Stub that offers no authentication.
DummyElGamalEngine	Fake ElG E and D, useful for when performance isn't being tested
ElGamalAESEngine	Handles the actual ElGamal+AES encryption and decryption scenarios using the supplied keys and data.
ElGamalEngine	Wrapper for ElGamal encryption/signature schemes.
HMAC256Generator	Calculate the HMAC-SHA256 of a key+message.
HMACGenerator	Calculate the HMAC-MD5-128 of a key+message.
KeyGenerator	Define a way of generating asymmetrical key pairs as well as symmetrical keys
SessionKeyManager	Manage the session keys and session tags used for encryption and decryption.
SHA1	NOTE: As of 0.8.7, use getInstance() instead of new SHA1(), which will return the JVM's MessageDigest if it is faster.
SHA1Hash	Because DSAEngine was abusing Hash for 20-byte hashes
SHA256Generator	Defines a wrapper for SHA-256 operation.
TransientSessionKeyManager	Implement the session key management, but keep everything in memory (don't write to disk).
TrustedUpdate	Handles DSA signing and verification of update files.
YKGenerator	Precalculate the Y and K for ElGamal encryption operations.
