How SCypher Works

A simple yet powerful encryption system that transforms your BIP39 seed phrase into another valid BIP39 phrase

The Encryption Process

Your Original BIP39 Seed + Password + Iterations
XOR Encryption with SHAKE-256
Encrypted BIP39 Seed Phrase

To decrypt: Use the same password and iterations with the encrypted phrase to get back your original phrase.

Blockchain Security

The decryption tool is permanently stored on Ergo blockchain. Cannot be altered, lost, or censored.

โšก

Always Available

Download anytime from the blockchain. No central servers or third parties required.

๐ŸŽฏ

Deterministic

Same password and iterations always produce the same result. Fully predictable and reliable.

Technical Details

  • Pure XOR encryption maintains BIP39 validity
  • SHAKE-256 provides cryptographic security
  • Iterative key strengthening for enhanced protection
  • Memory-secure operations with sensitive data cleanup
  • Cross-platform Bash implementation

๐Ÿ“ฆ How to Extract SCypherV2.sh.xz

The downloaded file is compressed with XZ format. Extract using:

๐Ÿง
Linux
xz -d SCypherV2.sh.xz
๐ŸŽ
macOS
xz -d SCypherV2.sh.xz
๐ŸชŸ
Windows
Use WinRAR, 7-Zip or similar

This ensures maximum decentralization while maintaining small blockchain footprint.

๐Ÿ” Blockchain Transparency

Every download is completely transparent and verifiable:

  • โœ… All script fragments are publicly stored on Ergo blockchain
  • โœ… No central servers - direct blockchain access
  • โœ… Immutable storage ensures script integrity
  • โœ… Open source verification of the reconstruction process
