@ohxxx/wedts

@ohxxx/wedts is the TypeScript-friendly npm package for the WED symmetric encryption protocol.

It wraps the generated WASM output from crypto-wasm and adds a stable JavaScript entrypoint plus TypeScript declarations.

Install

npm install @ohxxx/wedts

API

The package exports:

• encryptText(passphrase: string, plaintext: string): string
• decryptText(passphrase: string, token: string): string
• encryptJson(passphrase: string, value: unknown): string
• decryptJson<T = unknown>(passphrase: string, token: string): T

Text example:

import { decryptText, encryptText } from "@ohxxx/wedts";

const token = encryptText("shared-passphrase", "hello");
const plaintext = decryptText("shared-passphrase", token);

JSON example with type inference:

import { decryptJson, encryptJson } from "@ohxxx/wedts";

const token = encryptJson("shared-passphrase", { message: "hello" });
const payload = decryptJson<{ message: string }>("shared-passphrase", token);

Local Development

Install dependencies and rebuild the WASM output:

cd packages/wedts
npm install
npm run build:wasm

The build script compiles crates/crypto-wasm with wasm-pack and copies the generated assets into dist/wasm.

Test

Runtime test:

cd packages/wedts
npm test

Type test:

cd packages/wedts
npm run typecheck
