Bug: Decrypt Function Fails Due to Incorrect Parameter Passing

Description:

This PR addresses a bug in the decryption process of the password management application. The issue occurs in the decrypt function, where the input is not handled correctly, resulting in a TypeError when attempting to split the input string.

Issue:

• Error Message: TypeError: text.split is not a function or its return value is not iterable
• This error arises because the input to the decrypt function is incorrectly passed as an object instead of a string.

Changes Made:

1. Fixed the decrypt Function:
   • Updated the implementation to accept a single string input rather than an object.
   • Adjusted the code that calls the decrypt function to ensure the correct value is passed.

Code Changes:

Here are the relevant sections of code for reference:

Original decrypt Function:

const decrypt = (text) => {
  const [iv, encryptedData] = text.split(":");
  const ivBuffer = Buffer.from(iv, "hex");

  const decipher = crypto.createDecipheriv(
    "aes-256-cbc",
    Buffer.from(ENCRYPTION_KEY),
    ivBuffer
  );
  let decrypted = decipher.update(encryptedData, "hex", "utf-8");

  decrypted += decipher.final("utf-8");

  return decrypted;
};

Updated Usage in the Password Fetching Route:

const decryptedPassword = passwords.map((item) => {
  const [iv, encryptedData] = item.password.split(':');
  return { ...item, password: decrypt(item.password) }; // Corrected the function call
});

Testing:

• The application has been tested locally, and the bug has been resolved.
• All existing functionality works as expected after the changes.

Conclusion:

This fix ensures that the decryption process functions correctly and enhances the stability of the application.
