CryptKit is a developer's toolkit implementing several of the most modern and efficient cryptographic algorithms. The kit is primarily written in ANSI C for speed and subsequently wrapped with SWIG for ease of use in python. CryptKit is small and fast, mainly because it implements excellent algorithms: Rijndael (AES), SHA 256 bits, Elliptic Curve PKI, Diffie-Hellman key exchange and Nyberg-Ruppel signature/verification. These modules are combined to provide a faster, lighter and easier to use secure socket alternative to SSL. CryptKit is not compatible with SSL. Whereas SSL aims to support a wide variety of algorithms that essentially perform the same task ( like DES/RC4/RC2 or MD5/SHA ), CryptKit takes the minimalist approach of implementing only one version of each crypto primitve. Great care went into selecting the best of what was available.
