Verify Password of Encrypted Files with Node.js via C++

If Excel (xlsx, xlsb, xls, xlsm) and Open Office (ODS) files are locked with a password, Aspose supports simple password verification without parsing specific data of the files.

Verify the password of the encrypted file

To verify the password of the encrypted file, Aspose.Cells for Node.js via C++ provides the FileFormatUtil.verifyPassword(Uint8Array, string) method. This method accepts two parameters, the file stream and the password that needs to be verified.
The following code snippet demonstrates the use of the FileFormatUtil.verifyPassword(Uint8Array, string) method to verify whether the provided password is valid or not.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "EncryptedBook1.xlsx");

// Create a Stream object
const fs = require("fs");
const fstream = fs.readFileSync(filePath);

const isPasswordValid = AsposeCells.FileFormatUtil.verifyPassword(fstream, "1234");

console.log("Password is Valid: " + isPasswordValid);
