@chikawa222224/testchikawa222224_2

A Node.js hash library for the bundled _chikawa222224_testchikawa222224_2.bin binary file.

Hash calculation

The library calculates the hash of these bytes in order:

1. The complete bundled file bytes.
2. The binary attachment decoded from the Base64 argument.

In other words: hash(fileBytes + Base64Decode(base64Attachment)).

The default algorithm is SHA-256 and the result is returned as a lowercase hexadecimal string.

Usage

const { calculateHash } = require("@chikawa222224/testchikawa222224_2");

const attachmentBase64 = Buffer.from("attachment bytes").toString("base64");
calculateHash(attachmentBase64).then(console.log);

Calculate only the bundled file hash by omitting the attachment:

calculateHash().then(console.log);

Use another algorithm supported by Node.js:

calculateHash(attachmentBase64, "sha512").then(console.log);

API

calculateHash(base64Attachment = "", algorithm = "sha256")

Returns a Promise<string> containing the calculated hash. Invalid Base64 input or an unsupported algorithm rejects the promise.

binaryPath

Contains the absolute path of the bundled binary file.
