Blockchain Commons Envelope CLI (TypeScript)

Disclaimer: This package is under active development and APIs may change.

Introduction

@bcts/envelope-cli is a command line tool for manipulating Gordian Envelope data structures. Gordian Envelope is a smart document format that supports encryption, elision, and cryptographic assertions.

Features:

• Create and manipulate Gordian Envelopes
• Add assertions (subject-predicate-object triples)
• Encrypt and decrypt envelope contents
• Sign and verify envelopes
• Elide (redact) portions of envelopes while maintaining verifiability
• Work with XID (Extensible Identifier) documents
• Pattern matching for querying envelope structures

Rust Reference Implementation

This TypeScript implementation is based on bc-envelope-cli-rust v0.31.0 (commit).

Installation

# Install globally
bun add -g @bcts/envelope-cli

# Or run directly with bunx
bunx @bcts/envelope-cli --help

Usage

Creating Envelopes

# Create a simple envelope with a string subject
envelope subject string "Hello, World!"

# Create an envelope with assertions
envelope subject string "Alice" | envelope assertion add pred string "knows" obj string "Bob"

# Wrap an envelope
envelope subject string "Secret" | envelope wrap

Working with Assertions

# Add a predicate-object assertion
envelope assertion add pred string "name" obj string "Alice"

# Find assertions matching a pattern
envelope assertion find pred string "name"

# Remove an assertion
envelope assertion remove pred string "name"

Encryption and Signing

# Generate a private key
envelope generate prvkeys

# Sign an envelope
envelope sign --prvkeys $PRIVATE_KEY

# Verify a signature
envelope verify --pubkeys $PUBLIC_KEY

# Encrypt an envelope
envelope encrypt --key $SYMMETRIC_KEY

# Decrypt an envelope
envelope decrypt --key $SYMMETRIC_KEY

XID Documents

# Create a new XID document
envelope xid new $PRVKEYS

# Add a service to XID
envelope xid service add --name "website" --uri "https://example.com"

# Work with provenance marks
envelope xid provenance get
envelope xid provenance next

Elision

# Elide a portion of an envelope
envelope elide removing $DIGEST

# Reveal elided content
envelope elide revealing $DIGEST
