Why Cyphr ?

Most key management solutions either introduce unnecessary latency or are overly complex.

Cyphr focuses on:

• Fast read access through edge caching.
• Strong encryption guarantees.
• Minimal operational overhead.

Features

• Edge Encryption (AES-256-GCM)
  Secrets are encrypted at the edge before persistence.

• Low-Latency Reads
  P95 read latency reduced by ~65% using Cloudflare KV caching.

• Edge-Native Execution
  Runs on Cloudflare Workers for globally distributed execution.

• Minimal API Design
  Simple and predictable API for managing keys.

• Lightweight Dashboard Fast interface for managing secrets.

Quick Start

1. Sign in using GitHub
2. Store an API key
3. Retrieve secrets via the dashboard

Cyphr handles encryption, caching, and storage automatically.

Architecture

Below is a simple system design diagram to explain the basic flow of data

Performance

• ~82% reduction in P95 read latency using Isolate Memory and KV caching.
• Optimized for read-heavy workloads.

Security

• AES-256-GCM encryption applied before persistence.
• Stateless authentication model.
• No plaintext secrets stored.

Tech Stack

• Frontend: HTML, CSS, Bulma, JavaScript (ES6+)
• Backend: Node.js, Hono
• Auth: Supabase Auth
• Database: PostgreSQL (Neon)
• Edge Runtime: Cloudflare Workers
• Caching: Cloudflare KV

Notes

• Designed for developer-focused workflows.
• Focused on performance and simplicity.
• Not intended as a full enterprise secrets manager.
