Hi, Thanks for your great work. I am trying to translate this into JAVA, and i need little help from your side. Right now i am learning the code, ie. written in C. So, i have many doubts and question regarding many portions. Can you help me in this project ..?

Regards, Jinto Antony

Decryption is also implemented. See RLWE_dec2() inside lwe.h.

After cloning the repo you should navigate to x86/ and then type "make".

Converting this code to java shouldn't be a problem.

Yes this can be done. Currently there is a "Enc/Dec" unit test inside x86/main.c. It generates random messages, encrypts the message, and then decrypts it. Currently, message_gen2 is used to generate the random messages. Currently, the RLWE_enc2 function takes the parameter "m" that consists of an array of 1-bit values. Therefore, you will have to encode your string to an array of 1-bit values.

Ring-LWE was developed to provide a crypto algorithms that will be secure when quantum computers one day become reality. RSA and ECC would become broken if quantum computers are available. We don't really care about the performance of Ring-LWE on quantum computers, just that the crypto will still be OK if quantum computers one day become reality.

uint16_t is a 16-bit unsigned integer. uint32_t is a 32-bit unsigned integer.
