ocaml-eris

OCaml implementation of the Encoding for Robust Immutable Storage (ERIS).

This library can be used to encoded and decode content with ERIS. Features include:

  • Streaming encoding
  • Random-access decoder
  • Cross-platform support

Cryptographic Primitives

We provide multiple implementations of the necessary cryptographic primitives (Blake2b and ChaCha20). End-users can choose which implementation to use by specifying the package in their dependencies. Currently following implementations are provided:

  • eris.crypto-monocypher: Uses the Monocypher cryptographic library via the ocaml-monocypher bindings. This implementation works well on the Unix platform and is selected by default.
  • eris.crypto-zig: Uses the cryptographic primitives provided in the Zig standard library. This implementation works on the Unix platform and requires the Zig compiler installed.
  • eris.crypto-wasm: Uses the cryptographic primitives provided by the Zig standard library compiled to WASM. This implementation can be used with js_of_ocaml and requires the Zig compiler installed. The WASM code is bundled using Crunch so users do not need to worry about provisioning or loading WASM.

A pure OCaml implementation of Blake2b and ChaCha20 would be very nice.

See also the Digestif project that uses the same linking trick.
