GoPaillier
Extended version of a Paillier cryptosystem implementation in Go.
Features
- Extended Paillier cryptosystem implementation with negative number support (read more here).
- Uses Standard Form notation to encode numbers allowing to use Paillier encryption scheme over integer and floating points numbers (read more about number package here).
- Allows four different operations:
- Addition between encrypted and plain numbers:
A' + B. - subtraction between encrypted and plain numbers:
A' + (-B). - Multiplication between encrypted and plain numbers:
A' * B. - Division between encrypted and plain numbers:
A' * 1/B.
- Addition between encrypted and plain numbers:
Installation
go get github.com/lucasmenendez/gopaillier@latest
Examples
There are three basic examples ready to help starting with the library:
- Basic Paillier example: Source code.
- Median example: Source code.
- SDK example: Source code.
