Tcl Requires Chilkat v11.0.0+

Workaround for the deprecated EncryptBytes and DecryptBytes methods

Shows how to replace the deprecated DecryptBytes method. (Chilkat is moving away from the use of CkByteData.) Tcl

load ./chilkat.dll

set success 0

set crypt [new_CkCrypt2]

CkCrypt2_put_CryptAlgorithm $crypt "aes"

#  ------------------------------------------------------------------------
#  The EncryptBytes and DecryptBytes methods are deprecated and will eventually be removed.

set unencryptedBytes [new_CkByteData]

CkByteData_appendEncoded $unencryptedBytes "AABBCCDDEEFF01020304" "hex"

set encryptedBytes [new_CkByteData]

set decryptedBytes [new_CkByteData]

set success [CkCrypt2_EncryptBytes $crypt $unencryptedBytes $encryptedBytes]
set success [CkCrypt2_DecryptBytes $crypt $encryptedBytes $decryptedBytes]

#  ------------------------------------------------------------------------
#  Replace the above CkByteData usage with the following code:
#  (Chilkat is moving away from using CkByteData)

set bd [new_CkBinData]

CkBinData_AppendEncoded $bd "AABBCCDDEEFF01020304" "hex"

#  in-place encrypt

#  in-place decrypt
