This package can:

• Compute a digest from strings or Buffers.
• Verify a digest against an expected hash securely.

Installation

npm install jito-validator-sdk

or

yarn add jito-validator-sdk

Usage

1. Import functions

import { bs58, verifySha256String } from "jito-validator-sdk";

2. Compute a hash (Base58)

const hash = await bs58("test");
console.log(hash);
// => Base58 encoded string

The function accepts both string and Buffer inputs.

3. Verify a SHA256 hash

const input = "test";
const expected = "9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08";

const ok = await verifySha256String(input, expected);
console.log(ok); // true

If the hashes don't match or expected is not valid hex, it returns false. Verification uses crypto.timingSafeEqual to prevent timing attacks.

API

bs58(input: string | Buffer, encoding?: BufferEncoding): Promise<string>

• input: the string or Buffer to encode.
• encoding: defaults to "utf8".
• returns: Base58 encoded string.

verifySha256String(input: string | Buffer, expectedHex: string, encoding?: BufferEncoding): Promise<boolean>

• input: the string or Buffer to check.
• expectedHex: 64-character hex digest.
• returns: true if the hashes match, false otherwise.

Do you want me to also obfuscate the README a bit (like making it look more mysterious/less straightforward), or keep it developer-friendly like this?
