Private Encryption for PCB Schematic Review

Private Encryption for Schematic Review

Encrypt your design files before uploading using industry-standard OpenSSL. Your plaintext files never leave your facility. Your encryption key is used only in memory during processing and is never stored.

          Key Benefits:
          Files encrypted with AES-256-CBC (same encryption used by banks and governments)
Only you possess the decryption key
Your key is used in memory during processing, then discarded
Input files deleted immediately after processing
Results remain encrypted at rest — you decrypt in your browser
Even if our servers were breached, your designs remain encrypted

        

How It Works: Encryption Flow

You encrypt your design files locally before they ever leave your facility:

Encryption Flow - Design files encrypted with OpenSSL before upload

How It Works: Server Processing

On Tomachie servers, your files remain encrypted at rest. Decryption occurs only in memory during processing:

Processing Flow - Files decrypted in memory, never written to disk

Security Properties

Property	How It's Achieved
Encryption Standard	AES-256-CBC — 256-bit key. Same standard used by TLS 1.3, banking systems, and government classified networks.
At-Rest Encryption	Files remain encrypted on Tomachie servers at all times. Decryption occurs only in memory during processing.
Zero Knowledge	Your encryption key is used in memory then discarded. Only you possess it.
Auditability	Uses OpenSSL — open source, extensively audited, FIPS 140-2 certified versions available.
Key Strength	256-bit random key = 2²⁵⁶ possible combinations. Computationally infeasible to brute-force.

How Secure Are Your Files Today?

Consider how your design files are typically stored: on a shared server, a developer's laptop, or in cloud storage. In most organizations, these files sit in plaintext — accessible to anyone with network credentials.

Typical Corporate Storage

Files in plaintext on shared drives
Accessible to IT administrators
Included in backup systems
Network credentials = full access

Tomachie Private Encryption

AES-256 encrypted before upload
Only you hold the key
Key used in memory, never stored
Results encrypted at rest

Security Comparison - Typical corporate storage vs Tomachie encrypted

Your encrypted upload to Tomachie may actually be more secure than files sitting on your own company's servers.
