paswords's Issues

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.

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.
