paswords's Issues

A secret key for encrypting passwords should be secret, even for the server owner

Currently crypto is used to encrypt and decrypt passwords:

paswords/src/lib/crypto.ts

Lines 1 to 37 in f955d50

 const crypto = require("crypto"); 

 const algorithm = "aes-256-cbc"; 

 const secretKey = process.env.SECRET_KEY; 

 export type CipherType = { 

 iv: string; 

 content: string; 

 }; 

 export const encryptPass = (text: string) => { 

 const iv = crypto.randomBytes(16); 

 const cipher = crypto.createCipheriv(algorithm, secretKey, iv); 

 const encrypted = Buffer.concat([cipher.update(text), cipher.final()]); 

 const data: CipherType = { 

 iv: iv.toString("hex"), 

 content: encrypted.toString("hex"), 

 }; 

 return data; 

 }; 

 export const decryptPass = (data: CipherType) => { 

 const decipher = crypto.createDecipheriv( 

 algorithm, 

 secretKey, 

 Buffer.from(data.iv, "hex") 

 ); 

 const decrpyted = Buffer.concat([ 

 decipher.update(Buffer.from(data.content, "hex")), 

 decipher.final(), 

 ]); 

 return decrpyted.toString(); 

 };

The issue with this is that the secret key is known to the server owner in order to encrypt and decrypt passwords.

Add password generator

Zoom in on input field when entering password

Fix internal server error

When the user navigates to /pwd/[pwd]/iv/[iv], and the iv is wrong, a server error occurs. This is because the iv does not match content and when the decryption is ran it returns an error.
