e-CryptIt Engine is a REALbasic plugin to do encryption, encoding,
compression, checksums and hashing.

Main features:

Encryption:
   *    e-CryptIt - (Chained) (PPC, Carbon, x86)
   *    Blowfish ECB unchained mode
     (64 bit blocks - up to 448 bit key) (PPC,Carbon, x86)
   *    Blowfish CBC chained mode
     (64 bit blocks - up to 448 bit key) (PPC,Carbon, x86)
   *    Twofish ECB unchained mode
     (128 bit blocks - 128,192 and 256 bit keys) (PPC,Carbon, x86)
   *    Twofish CBC chained mode
     (128 bit blocks - 128,192 and 256 bit keys) (PPC,Carbon, x86)

Encoding/Decoding:
   *    e-CryptIt Flexible (PPC,Carbon,x86)
   *    Base64 (PPC,Carbon,x86)
   *    BinHex (PPC,Carbon,x86)
   *    MacBinary III (PPC,Carbon)
   *    AppleSingle / Double (PPC,Carbon)
   *    UUCoding (PPC,Carbon,x86)

Compression:
   *    Zip on strings (PPC,Carbon,x86)
   *    Zip on filestreams (.z format) (PPC,Carbon,x86)

Checksums:
   * CRC32 (PPC,Carbon,x86)

   *    Adler32 (PPC,Carbon,x86)
Hashing:
   *    MD5 (PPC,Carbon,x86)
   *    SHA (PPC,Carbon,x86)
   *    SHA1 (PPC,Carbon,x86)

Keyed-Hashing:
   *    HMAC-MD5 (PPC,Carbon,x86)
   *    HMAC-SHA1 (PPC,Carbon,x86)

New in 7.0:
    * Added a BlowfishECB class (This replaces the old functions).
    * Added a BlowfishCBC class which adds a CBC chained
      Blowfish encryption to the plugin.
    * Added a TwofishECB class which adds a ECB unchained
      Twofish encryption to the plugin.
    * Added a TwofishCBC class which adds a CBC chained
      Twofish encryption to the plugin.
    * Added a IEncryptionAlgorithm Interface which BlowfishECB
      BlowfishCBC, TwofishECB and TwofishCBC implement.
    * Removed the old function based BlowFish ECB encryption
      and all the ByRef string referencing relating to it.
    * Added new example projects for the new algorithms.
    * The ZStream class is now implemented with native
      MacOS calls rather that MSL calls making it 35% smaller on
      Carbon and 50% smaller on PPC.
    * Fixed a bug with the ZStream that made it crash when used
      on OS 8.6.
    * Fixed a minor memory leak in the ZStream constructor.
    * The ZStream now Implements the IStreamWriter and
      IStreamReader Interface.
    * The ZStream now can take IStreamReader and IStreamWriter
      as a constructor parameter, which add the ability to
      do in memory compression and decompression.
