🌱 Blockchain Commons SeedTool Command Line Tool

by Wolf McNally and Christopher Allen

NOTE: Preview version. Not ready for production use.

Introduction

seedtool is a command-line tool for creating and transforming cryptographic seeds of the sort commonly used by blockchain applications.

Deprecation of C++ SeedTool

The original SeedTool was written in C++ and is now deprecated. The new SeedTool is a complete rewrite in Rust. The new SeedTool's inputs and outputs are mostly compatible with the old SeedTool, and most of the same command line options are supported. The new SeedTool is more flexible and extensible, and is designed to support additional functionality.

The new SeedTool also exclusively uses Gordian Envelope for exporting and importing seeds with metadata, for sharding seeds with SSKR, and for writing and reading seeds in multipart UR format.

If you have the old SeedTool installed, you should uninstall it before installing the new SeedTool, or ensure that the new SeedTool is in your PATH before the old SeedTool.

Installation

To install from crates.io, run:

cargo install seedtool-cli

To install from source, clone this repo, change to its root directory and run:

cargo install --path .

Examples

• Examples of usage can be found in USAGE.md.
• The full user guide is in MANUAL.md.

Version History

0.1.7: October 16, 2024

• #5 Improved error message for failed SSKR join.
• #6 Fixed bug in SSKR join that caused it to fail for certain valid combinations of shares.
• Increased robustness of SSKR join by ignoring invalid shares (often blank lines or comments) in input.

0.1.6: July 11, 2024

• The formats base6, base10, bits, cards, dice, and ints, are intended to be used as user-provided input entropy for generating seeds. seedtool can use them as input to generate a seed in any of the other formats, or it can generate these directly using the random input mode (which you only would need to do when simulating user-generated entropy). However, seedtool will now return an error if any of these formats are used for output with anything other than random input (the default). This means it will also return an error if asked to convert between these entropy input formats, for example, from bits to dice, as these are not reversible conversions.

0.1.5: July 1, 2024

• No significant changes.

0.1.4: June 20, 2024

• The new --sskr-format (-s) option can be used to specify SSKR output format, including envelope (the default), bytewords (standard, minimal, or URI styles), and ur:sskr.
• Parsing SSKR shares autodetects the format, and will handle all of the above formats, and also the legacy ur:crypto-sskr format.

Status - Alpha

seedtool is currently under active development and in the alpha testing phase. It should not be used for production tasks until it has had further testing and auditing. See Blockchain Commons' Development Phases.

Discussions

The best place to talk about Blockchain Commons and its projects is in our GitHub Discussions areas.

Gordian Developer Community. For standards and open-source developers who want to talk about interoperable wallet specifications, please use the Discussions area of the Gordian Developer Community repo. This is where you talk about Gordian specifications such as Gordian Envelope, bc-shamir, Sharded Secret Key Reconstruction, and bc-ur as well as the larger Gordian Architecture, its Principles of independence, privacy, resilience, and openness, and its macro-architectural ideas such as functional partition (including airgapping, the original name of this community).

Gordian User Community. For users of the Gordian reference apps, including Gordian Coordinator, Gordian Seed Tool, Gordian Server, Gordian Wallet, and SpotBit as well as our whole series of CLI apps. This is a place to talk about bug reports and feature requests as well as to explore how our reference apps embody the Gordian Principles.

Blockchain Commons Discussions. For developers, interns, and patrons of Blockchain Commons, please use the discussions area of the Community repo to talk about general Blockchain Commons issues, the intern program, or topics other than those covered by the Gordian Developer Community or the Gordian User Community.
