# IBM/fhe-toolkit-linux

IBM Fully Homomorphic Encryption Toolkit For Linux. This toolkit is a Linux based Docker container that demonstrates computing on encrypted data without decrypting it! The toolkit ships with two demos including a fully encrypted Machine Learning inference with a Neural Network and a Privacy-Preserving key-value search.

## What it is
IBM's Fully Homomorphic Encryption Toolkit for Linux, a Docker-based toolkit demonstrating computation on encrypted data without decryption, with demos including encrypted neural network inference and privacy-preserving key-value search. The repository is now archived and superseded by IBM's HElayers SDK.

## Use cases
- compute on encrypted data without decrypting it
- run machine learning inference on encrypted inputs
- perform privacy-preserving key-value search
- experiment with fully homomorphic encryption on Linux
- learn FHE through sample demos and tutorials

## When to choose
- you want to explore FHE concepts with ready-made demos in a container
- you need a historical reference implementation of IBM's FHE toolkit

## When to avoid
- you need actively maintained FHE tooling - use IBM HElayers or other supported libraries instead
- you need production-grade homomorphic encryption performance
- you are not working on Linux or Docker

## Facets
- artifact type: library
- maturity: abandoned
- function: cryptography, security, machine-learning, search-engine, sdk
- domain: security, privacy, machine-learning, developer-tools
- platform: cpp, python
- tags: fully-homomorphic-encryption, fhe, privacy-preserving-computation, encrypted-compute, docker-container, helayers, ibm, linux, docker
