3DES Test Vector

Example for 3-key 3DES encryption (192-bit) to match a test vector produced by both (non-Chilkat) PHP code and C# code using the .NET Framework.

PHP code to produce identical output: PHP 3DES Test Vector

C# code to produce identical output: C# 3DES Test Vector

use chilkat;

$crypt = new chilkat::CkCrypt2();

$success = $crypt->UnlockComponent("Anything for 30-day trial.");

    print "Crypt component unlock failed" . "\n";

#  Specify 3DES for the encryption algorithm:
$crypt->put_CryptAlgorithm("3des");

$crypt->put_CipherMode("ecb");

#  KeyLength must be 192.  3DES is technically 168-bits;
#  the most-significant bit of each key byte is a parity bit,
#  so we must indicate a KeyLength of 192, which includes
#  the parity bits.
$crypt->put_KeyLength(192);

#  Pad with zeros
$crypt->put_PaddingScheme(3);

#  EncodingMode specifies the encoding of the output for
#  encryption, and the input for decryption.
#  It may be "hex", "url", "base64", or "quoted-printable".
$crypt->put_EncodingMode("hex");

#  The secret key must equal the size of the key.  For
#  3DES, the key must be 24 bytes (i.e. 192-bits).
$keyAscii = "1234567890123456ABCDEFGH";
$crypt->SetEncodedKey($keyAscii,"ascii");

#  Encrypt.
#  The result should be:
#  13d4d3549493d2870f93c3e0812a06de467e1f9c0bfb16c070ede5cabbd3ca62f217a7ae8d47f2c7bf62eb309323b58b
$encStr = $crypt->encryptStringENC("The quick brown fox jumped over the lazy dog");
print $encStr . "\n";

#  Now decrypt:
$decStr = $crypt->decryptStringENC($encStr);
print $decStr . "\n";
