Package net.i2p.crypto

Interface Summary
EntropyHarvester Allow various components with some entropy to feed that entropy back into some PRNG.
 

Class Summary
AESEngine Dummy wrapper for AES cipher operation.
AESInputStream This reads an underlying stream as written by AESOutputStream - AES256 encrypted in CBC mode with PKCS#5 padding, with the padding on each and every block of 16 bytes.
AESOutputStream This writes everything as CBC with PKCS#5 padding, but each block is padded so as soon as a block is received it can be decrypted (rather than wait for an arbitrary number of blocks to arrive).
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 Primes for ElGamal and DSA from http://www.ietf.org/proceedings/03mar/I-D/draft-ietf-ipsec-ike-modp-groups-05.txt
DHSessionKeyBuilder Generate a new session key through a diffie hellman exchange.
DSAEngine  
DummyDSAEngine Stub that offers no authentication.
DummyElGamalEngine Fake ElG E and D, useful for when performance isn't being tested
DummyPooledRandomSource  
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 of a key+message.
KeyGenerator Define a way of generating asymetrical key pairs as well as symetrical keys
PersistentSessionKeyManager Expose the functionality to allow people to write out and read in the session key and session tag information via streams.
SessionKeyManager Manage the session keys and session tags used for encryption and decryption.
SHA1 The FIPS PUB 180-2 standard specifies four secure hash algorithms (SHA-1, SHA-256, SHA-384 and SHA-512) for computing a condensed representation of electronic data (message).
SHA1Test  
SHA256Generator Defines a wrapper for SHA-256 operation.
TransientSessionKeyManager Implement the session key management, but keep everything in memory (don't write to disk).
TransientSessionKeyManager.TagSet  
TrustedUpdate Handles DSA signing and verification of update files.
YKGenerator Precalculate the Y and K for ElGamal encryption operations.
