to anonyme Designers: send me your ideas or remarks or implement more hash's and
                      cipher's to make this Packages to the biggest for Delphi and BCB :-)
                      (i.E. Cipher WAKE, LOKI97, Serpent, Yarrow, DEAL, SEAL,
                                   FEAL, NSEA, REDOC II & III, Lucifer, a3a8
                                   and many more, but to many for me)

-------------------------------------------------------------------------------------------

History:     Beginning at Feb 1999 to Aug 1999

-------------------------------------------------------------------------------------------

Version 3.0

 - Internet RFC2289/RFC1760/RFC2444 One Time Password Routines added
 - Internet RFC2104 HMAC Support
 - String Management (Converting) added
 - Object Hiearchy changed, all THash_xxx,TCipher_xxx,TRandom_xxx and TCompress_xxx are
   now Descends from TProtection. Now, a multiple chaining from all above Classes supported.
 - Now absolutly D2 compatible.

 - Full reorganization, better Compilerversions Management.
 - Speedup, i.E. Blowfish > 8 Mb/sec (fantastic :-), Q128 > 10 Mb/sec,
            TEA > 6 Mb, IDEA > 2.5 Mb/sec, Twofish > 6 Mb/sec, all on PII 266MHz
 - Twofish changed, old was bad.
 - In all Hashclasses changed the buggy Buffermanagement.
 - StrToBase64 and Base64ToStr changed and exchanged, now produce correct Results.
 - Property "IncludeHashKey" removed, make TCipher Class uniform

 - New Cipher Modes added,
   cmCBCMAC, cmCTSMAC, cmCFBMAC - Message Authentication Codes, Input Data are readonly
   cmCBC, cmCTS, cmCFB supportes now MAC's (Message Authentication Code)
   Demo to use these can You find in ResFrm.pas or GenForm.pas.
 - New Cipher Method "CalcMAC()" to calculate a MAC after any en/decryption

 - Old Cipher.pas splitted in two Files, Cipher.pas contains now a good Selection.
   Cipher1.pas contains all other Ciphers. In many cases are 40 Ciphers to big.

 - New a TRandom Basicclass for Random Number Generation,
 - TRandom_LFSR (Linear Feedback Shift Register) a fast Implementation with variable
   Period from 2^64-1 to 2^2032-1 (astronomical :-), with using from Cipher.pas these
   Randomclasses can be automaticaly cryptographicaly secure.

 and many more...


------------------------------------------------------------------------------------------

Version 2.3

 maked compatible with BCB 3 and 4, removed all abstract Methods and NewInstance Methods.

 new:            Secure Random Number Generator with a Period 2^256-1
                 included in RNG.pas
 added:          in Hash.pas and Cipher.pas Secure Random Number Generator Support

 specialy:       removed all fucking LOOP Statements in assembler core,
                 it's slow and produced bad iteration
                 as result: all Checksums speeded very up and
                            all Ciphers in cmCBC and cmCTS Mode speeded up
                            (i.E. TCipher_SCOP from 22 Mb/sec to 28 Mb/sec)

-------------------------------------------------------------------------------------------

Version 2.2

 added Cipher:   Square, all DES Cipher 7 types, Diamond II, Diamond II Lite, Sapphire II
 added Hash:     SHA, Square, Sapphire II (128, 160, 192, 224, 256, 288, 320)
 added Checksum: CRC16-CCITT Norm, CRC16-Standard Norm (XModem, ARC)

 bugfixes:       CRC32 offset Problem and in THash_CRC32.Done inverse the Result
                 Overlapping in TCipher.InternalCodeStream
                 DecodeString was called EncodeBuffer, now Decodebuffer

 added:          ProgressEvent (Gauges) for Cipher's and Hash's
                 Event OnProgress from TCipherManager and THashManager

 added:          more Examples

 changed:        DEC1 API, added a Demo to using DEC1.DLL

                 cmCTS Mode, XOR's the Data before and now after the encryption.
                 This has better Securityeffect when using a InitVector, the Output is
                 secure when a bad InitVector is used, ca 1% Speed lossed
                 cmCBC Mode is now equal to the old cmCTS Mode.


-------------------------------------------------------------------------------------------

Version 2.1

 added:          Self-Test support, Methods TCipher.SelfTest and TCipher.TestVector
                                    Methods THash.SelfTest and THash.TestVector

                 Cipher Init-checking, property TCipher.Initialized


 added Cipher:   TEAN, SCOP (very fast), Q128, 3Way, Twofish, Shark
 added Hash:     Snefru, RipeMD128, RipeMD256, RipeMD320, Tiger


 added Rounds for THaval_xxxx, from 3-5

       3 Rounds 174 % faster than with 5 Rounds, PII 266 12.74 Mb/sec
       4 Rounds 121 % faster than with 5 Rounds, PII 266  8.88 mb/sec
       5 Rounds                                  PII 266  7.32 mb/sec

       THash_Haval256           default Rounds is 5
       THash_Haval224 / 192     default Rounds is 4
       THash_Haval160 / 128     default Rounds is 3

 added in TCipherManager: Methods EncodeString(), DecodeString(),
                                  EncodeBuffer(), DecodeBuffer()

 added Low Level API in unit DEC_API.pas and Low Level DLL for use without Delphi


 changed:        Endian conversions routines, SwapInteger and SwapIntegerBuffer
                 use now Processor specific code to speedup the conversion

 bug fixes:      assember code in XORBuffers save now register EDI
                 TCipher.EncodeString and DecodeString changed,
                 old code produced Access Violation's

 speeded up:     TCipher_Cast128   145 %
                 TCipher_Cast256   118 %
                 TCipher_Blowfish  130 %
                 TCipher_Gost      139 %
                 TCipher_Mars      125 %

 speeded up:     THash_MD4         137 %
                 THash_MD5         126 %
                 THash_SHA1        134 % for <= 386   and 148 % for >= 486 CPU
                 THash_RipeMD160   140 %
                 THash_Haval       173 %
