At Nationaal Spaarfonds we created a new library that makes the Cryptography functionality from Windows accessible from Smalltalk. In the first version the following features are available:
- Symmetric encryption and decryption using RC4, DES, TripleDES and AES-256
- The MD5, SHA and SHA-256 hash functions
- The HMAC-MD5, HMAC-SHA and HMAC-SHA-256 message authentication functions.
The software is available on VAStGoodies.com (http://vastgoodies.com/maps/WinCrypt) and more information on how to use the library is available on my blog http://blog.doit.st/category/wincrypt/
