(DataFlex) Twofish Encryption - 128-bit, 192-bit, 256-bit

Twofish encryption. The Chilkat encryption component supports 128-bit, 192-bit, and 256-bit Twofish encryption in both ECB (Electronic Cookbook) and CBC (Cipher-Block Chaining) modes.

Procedure Test
    Handle hoCrypt

    End

    //  Set the encryption algorithm = "twofish"
    Set ComCryptAlgorithm Of hoCrypt To "twofish"

    //  CipherMode may be "ecb" or "cbc"
    Set ComCipherMode Of hoCrypt To "cbc"

    //  KeyLength may be 128, 192, 256
    Set ComKeyLength Of hoCrypt To 256

    //  The padding scheme determines the contents of the bytes
    //  that are added to pad the result to a multiple of the
    //  encryption algorithm's block size.  Twofish has a block
    //  size of 16 bytes, so encrypted output is always
    //  a multiple of 16.
    Set ComPaddingScheme Of hoCrypt To 0

    //  EncodingMode specifies the encoding of the output for
    //  encryption, and the input for decryption.
    //  It may be "hex", "url", "base64", or "quoted-printable".
    Set ComEncodingMode Of hoCrypt To "hex"

    //  An initialization vector is required if using CBC mode.
    //  ECB mode does not use an IV.
    //  The length of the IV is equal to the algorithm's block size.
    //  It is NOT equal to the length of the key.
    Move "000102030405060708090A0B0C0D0E0F" To sIvHex
    Send ComSetEncodedIV To hoCrypt sIvHex "hex"

    //  The secret key must equal the size of the key.  For
    //  256-bit encryption, the binary secret key is 32 bytes.
    //  For 128-bit encryption, the binary secret key is 16 bytes.
    Move "000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F" To sKeyHex
    Send ComSetEncodedKey To hoCrypt sKeyHex "hex"

    //  Encrypt a string...
    //  The input string is 44 ANSI characters (i.e. 44 bytes), so
    //  the output should be 48 bytes (a multiple of 16).
    //  Because the output is a hex string, it should
    //  be 96 characters long (2 chars per byte).
    Get ComEncryptStringENC Of hoCrypt "The quick brown fox jumps over the lazy dog." To sEncStr
    Showln sEncStr

    //  Now decrypt:
    Get ComDecryptStringENC Of hoCrypt sEncStr To sDecStr
    Showln sDecStr
