Overview

JSON Hash

Latest version LGPL 3.0 Deno Doc (API references) GitHub Actions

This package contains the following JSON utilties for Deno:

  • digest.ts provides cryptographic hash digests of JSON trees. It guarantee that digest() function always returns the same digest for the equivalent JSON trees. It means you don't have to care about the order of how object keys occurs or how characters in string are encoded. It also provides various hash algorithms; see also the docs of Deno's std/crupto module.

  • merkle.ts provides hash digests of JSON Merkle trees. It can be used for efficient diff of two large trees or updating a deep leaf in a large tree.

  • canon.ts provides canonicalization of JSON trees. This complies with RFC 8785, also known as JCS (JSON Canonicalization Scheme).

  • mod.ts re-exports everything in the above files.

See also Deno Doc for the complete API references.

  • Support web browsers

    Support web browsers

    Although the project is mainly targeted to Deno as of now, it is open to expand its target runtimes including web browsers in particular. There would be subtasks to let it support web browsers:

    • [ ] Compatibility. The current implementation probably depends on several APIs which are unavailable on web browsers. These should be rewritten in the more portable and standard way.
    • [ ] Unit tests. Currently the unit tests are based on Deno's built-in testing framework. The unit tests should be possible to run on all supported runtimes.
    • [ ] Packaging. Although Deno uses ESM by default, as the entire source code is written in TypeScript, it still needs to be compiled to JavaScript, and preferably, bundled into a single .jsm file so that users can use it using <script type=module> tag.
    • [ ] CI. Everything above needs to be continuously integrated and delivered.
