CryptoLib

The CryptoLib COM library uses state-of-the-art encryption algorithms such as AES (Rijndael) and TwoFish for symmetric encryption with up to 256-bit keys, and RSA for asymmetric encryption with up to 2,048-bit keys. Three hash algorithms (MD5, SHA, and Tiger) are also included, and CryptoLib can create and verify digital signatures. The library was written in ATL, making it light and suitable for Web sites and Internet applications. Samples in VB, VBScript, and VC++ are included.
