Hello OpenFHE community,

We would like to share the Sirraya HE Playground, an educational browser-based implementation of RNS BFV that runs entirely in WebAssembly (WASM).

Demo:

[https://www.sirraya.org/he-playground](https://www.sirraya.org/he-playground)

Current capabilities:

RNS representation and visualization  
BFV encryption workflow  
Homomorphic addition  
Interactive exploration of ciphertext arithmetic  
Runs completely in the browser (no installation required)

Our goal is to make FHE concepts more accessible to students, researchers, and developers by providing a lightweight environment for experimenting with BFV internals and understanding how operations behave at the RNS level.

Roadmap:

Ciphertext multiplication  
Relinearization  
Modulus switching  
Additional BFV primitives  
More educational visualizations

We would appreciate feedback from the OpenFHE community regarding:

Educational usefulness  
Missing features  
Potential interoperability with OpenFHE examples and tutorials  
Ideas for future extensions

We hope this can serve as a useful learning tool for newcomers exploring homomorphic encryption.

Feedback and suggestions are welcome.
