Hello, thank you for this library!

I've started experimenting with it decided to implement an email spam detection example. It is not meant to be production ready, just exploration. The repository is here: https://github.com/dartdart26/fhe-is-mail-spam

If you are open to adding code, it is already a working example (can be put in the transpiler/examples directory). I will be working on making it more feature-rich, i.e. having real client/server, be more practical and more. I generate C++ code via Python, but I can work on other methods. I guess these can be generalised and I am sure you've thought about it. I am just approaching it from the perspective of C++ developer without FHE experience.

Hey guys, first thank you for the code and the libary.

I just tried the docker installation guide on my arch linux system. I got the error which you describe in the troubleshooting area, but I got it with the docker image.

The command '/bin/sh -c bazel build ...' returned a non-zero code: 

Is there any way to fix this?

Best regards

I managed to build this project in docker on Linux, and run the example code. However, the computation takes a quite long to complete.

Specifically, I run

bazel run //transpiler/examples/calculator:calculator_tfhe_testbench

and the first computation (10 * 20) takes around 460 seconds with 100% CPU on single core to compute. My computer has a 4th gen i7 CPU.

I am quite new to homomorphic encryption. So I am not sure how long should it take. Is my result similar to the expected performance?

Hi, have been trying to run several provided examples (pls see attached) but keeps having failures. using --verbose_failures and --sandbox_debug reveals that: "external/com_google_xls/xls/passes/pass_base.h:20:10: fatal error: filesystem: No such file or directory" Kindly advise. Much appreciated. NB: am running ubuntu 18.04 VM with bazel 4.0.0 as instructed at: https://github.com/google/fully-homomorphic-encryption/tree/main/transpiler

Thank you failure.log

The README file links to https://groups.google.com/g/fhe-open-source-users but when visiting that group as a logged-in user I'm presented with permission denied error.

1. Fully Homomorphic Library with Bazel in Container Environment.
2. Created a new example in Fully Homomorphic Library using openfhe https://github.com/openfheorg/ library.
3. The example I am trying to run is https://github.com/openfheorg/openfhe-development/blob/main/src/pke/examples/simple-integers-serial-bgvrns.cpp
4. The example runs fine when I compile and execute openfhe as a standalone project (independent of Fully Homomorphic Library).
5. When I try to run the same example using bazel as part of Fully Homomorphic Library, I get a compilation error, show below

My steps: A. I had cloned the repo B. Created a new folder in examples to host my example code and made a new BUILD file C. The build file is

Everything else in the project is constant, and not been altered. Trying to understand why the openfhe example is not working within the Fully Homomorphic encryption Library.

Good Morning, I want to create a script in which the input are the Encrypted number and not the plaintext. I want to realize a simple sum. How can represent the Encrypted Number through int type? Is possible to encode o to serialize the ciphertext in order to give it like input? Thank you very much!

This demo simulates a service that checks if a mail is spam without the server seeing the mail or the result. If a mail contains "evil.url", it will be classified as spam.

Add test benches, an unit test and update the README.

Hi,

First, I want to thank you for this project. Its really nice and has enormous potential.

I'm compiling from the sources on a EC2 machine. I had an error when I was at the examples compilation. The reverse string example. You will find the error messages hereafter. How can I fix this?

The simple sum example still worked. So I can continue my exploration.

Thanks in advance for your help.

Kind Regards, M
