A: HsCipherSDK includes the following algorithms:

• 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

Q: Is the source code included when if purchase the library? What language is it developed in?

A: After you purchase HsCipherSDK you will receive full source code in C language. The library is developed in basic C style (not object oriented C++).

Q: What programming languages can the library be used with?

A: HsCipherSDK can be used with the following programming languages:
