cloudproof_js v10.0.0
Cloudproof Javascript Library
The library provides a Typescript-friendly API to the Cloudproof Encryption product of the Cosmian Ubiquitous Encryption platform.
Licensing
The library is available under a dual licensing scheme Affero GPL/v3 and commercial. See LICENSE.md for details.
Cryptographic primitives
The library is based on:
CoverCrypt algorithm which allows creating ciphertexts for a set of attributes and issuing user keys with access policies over these attributes.
CoverCrypt
offers Post-Quantum resistance.Findex which is a cryptographic protocol designed to securely make search queries on an untrusted cloud server. Thanks to its encrypted indexes, large databases can securely be outsourced without compromising usability.
FPE provides
Format Preserving Encryption
(FPE) techniques for use in a zero-trust environment. These techniques are based on FPE-FF1 which is described in NIST:800-38G.Anonymization:
Data anonymization
is the process of transforming data in such a way that it can no longer be used to identify individuals without the use of additional information. This is often done to protect the privacy of individuals whose data is being collected or processed.
Getting started
Please check the online documentation for details on using the CloudProof APIs.
You can also look the examples
directory for examples with multiple JS frameworks/technologies (the README
of the examples
folder can guide you to the best example for you use case).
Using in Javascript projects
This library is free software and is available on NPM public repository.
As a pre-requisite, the WASM binaries required for Findex and CoverCrypt must be fetched (or be manually copied from https://package.cosmian.com into src/pkg
directory):
python3 scripts/download_wasm.py
And next:
npm i cloudproof_js
(version before 3.1.0 were called cosmian_js_lib)
Versions Correspondence
CoverCrypt and SSE Findex scheme are wrapped in WebAssembly libraries (WASM) in cloudproof_rust.
