The next version of the Chilkat Crypt component (dated after 17-Oct-2007) will include support for Triple-DES (both 168-bit 3-key 3DES and 112-bit 2-key 3DES), older (and weaker) 56-bit DES, the RC2 block cipher, and the ARC4 stream cipher.
Over the next few days, a series of posts and examples will appear as Chilkat continues to test the pre-release software. The new encryption functionality is available in the Chilkat pre-release downloads.
This post will be updated to include links to posts and examples with information about 3DES, DES, RC2, and ARC4.
