HsCipherSDK Encryption Library

HsCipherSDK is an Encryption Library providing an API to a suite of symmetric key cryptographic algorithms and one way hash digital signature algorithms. The library includes the following block and stream cipher modules:

* AES (Advanced Encryption Standard) - FIPS 197

* DES and Triple DES (Data Encryption Standard) - FIPS-46-1, FIPS-46-3

* ARC4 (Alleged RC4) CAST-128 (a.k.a CAST5) - RFC 2144

* Blowfish algorithm

* Twofish algorithm

* MD5 message digest algorithm - RFC 1321

* SHA-1 (Secure Hash Algorithm) - RFC 3174

* SHA-256 (Secure Hash Algorithm) - FIPS 180-2

* SHA-512 (Secure Hash Algorithm) - FIPS 180-2

* Whirlpool ISO/IEC 10118-3

HsCipherSDK includes s standard DLL for use from C / C++, standard DLL for use from Visual Basic or any other languthat can use the standard dll. HsCipherSDK includes C Sharp wrapper DLL for use from C Sharp applications. HsCipherSDK itself is fully written in C (plain C style) and the source code is included.

HsCipherSDK allows the calling user application to perform the following operations:

* Encrypt and decrypt memory buffers with selected algorithm and key

* Encrypt and decrypt disk files with selected algorithm and key

* Digitally sign buffers using one of selected hashing algorithms

* Digitally sign disk files using one of selected hashing algorithms
