feat(js-client)!: Particle signatures [fixes DXJ-466] (#353)
* Introduce particle signatures * Fix particle id field in particle context * Fix types * Fix review comments * Remove init_peer_id from signature * Fix typo * Fix error msg * Fix async promise constructor antipattern * Refactor utils * Move text encoder outside * Use async/await * Update packages/core/js-client/src/connection/RelayConnection.ts Co-authored-by: shamsartem <[email protected]> * Hide crypto implementation beside KeyPair * Fix verify method * Comment verify method * Use particle signature instead of id * remove async/await from method * Fix type * Update packages/core/js-client/src/particle/interfaces.ts Co-authored-by: folex <[email protected]> * Update packages/core/js-client/src/particle/Particle.ts Co-authored-by: folex <[email protected]> * Fix review comment * Update pipe * set logging * try cache --------- Co-authored-by: shamsartem <[email protected]> Co-authored-by: folex <[email protected]>
