CFXWorks-Coldfusion: Encryption, Secure Messaging and Credit Card Processing
[CRYPTOGRAPHY] - CryptoXpress CF Overview

CryptoXpressTM CF: CryptoXpress CF is a ColdFusion tag that encrypts and decrypts data using the AES or TripleDES (3DES) algorithm. AES and TripleDES both qualify as "strong encryption" as defined by the National Institute of Standards and Technology (NIST). The tag can be used to custom develop solutions that require the ability to encrypt/decrypt or digest files or data. Digesting data results in the creation of a message digest sometimes called a digital signature.

64-bit Operating Systems:

Our CFX_ENCRYPT_AES 128 and CFX_ENCRYPT_AES 256 were written in the C programming language and compiled as 32-bit Windows' DLLs. These tags were originally authored in the 2001 timeframe. Since then there have been two significant changes that will impact some users of these tags.

  • Microsoft chose not to support 32-bit DLLs on their 64-bit operating systems. Therefore, our 32-bit tags, CFX_ENCRYPT_AES 128 and CFX_ENCRYPT_AES 256, will not work on 64-bit Microsoft operating systems.

  • The original AES standard and test vectors published by the National Institute of Standards and Technology (NIST) for AES encryption did not specifically address several issues relative to how keys and initialization vectors should be handled. This left room for interpretation that have and will caused cross platform and cross language incompatibilities. For example the inability to decrypt data encrypted on a different platform or encrypted using a different language.

CFXWorks does offer a new solution to both of the above issues called CryptoXpress CF. We offer to licensed users of our older 32-bit encryption tags a free upgrade to our Java encryption tag CryptoXpress CF. This tag will run on both 32-bit and 64-bit platforms. Most of our users have already elected to upgrade to this new tag.

Encryption/Decryption Algorithms Supported:
Algorithum Modes of Operation
AES 128-bit encryption
  • AES128/PKCS5Padding/CBC
  • AES 256-bit encryption
  • AES256/PKCS5Padding/CBC
  • Triple DES (3DES) encryption
  • 3DES/PKCS5Padding/CBC
    Message Digest Algorithms Supported:
  • MD5
  • SHA1
  • CryptoXpress CF users can deploy strong encryption and message digests without writing code Java, C, C++ or .Net code.
  • CryptoXpress CF can deploy best-of-breed cryptography techniques without knowing implementation details.
  • CryptoXpress CF produces results that are consistent with the standards published by the NIST.
  • The results produced by CryptoXpress CF are compatible across any Java enabled (1.4 or later) platform.
    Compatibility Mode:
    For many years CWorks sold C++ implementations of encryption and message digest solutions for ColdFusion. This included CFX_ENCRYPT_AES128 (128-bit), CFX_ENCRYPT_AES256 (256-bit), and CFX_MD5 tag. We have replace these tags with out lastest version called CryptoXpress CF, which supports most of the modes of operation supported by the original encryption tags including AES128/ECB, AES256/ECD, AES128/CBC and AES256/CBC. The digest results of this new tag are compatible with the original CFX_MD5 tag.
