Blockchain Commons Secure Components for TypeScript

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

Introduction

A collection of useful primitives for cryptography, semantic graphs, and cryptocurrency, primarily for use in higher-level Blockchain Commons projects. All the types are CBOR serializable, and a number of them can also be serialized to and from URs.

Also includes a library of CBOR tags and UR types for use with these types.

Rust Reference Implementation

This TypeScript implementation is based on bc-components-rust v0.31.1 (commit).

Limitations: SSH Agent Integration

The following features require platform-specific implementations and are not yet functional:

• SSH agent lock/unlock operations
• SSH signature schemes

These features will throw a CryptoError with kind SshAgent or Ssh when attempted. Use alternative methods:

• For key derivation: Use HKDF, PBKDF2, Scrypt, or Argon2id instead of SSHAgent
• For signing: Use Ed25519, Schnorr, Ecdsa, or Sr25519 schemes instead of SSH schemes
