Encrypt & Decrypt user credentials | Crypto-JS | Playwright Tutorial - Part 89

A demonstration of how to use CryptoJS to encrypt and decrypt data, including code examples and step-by-step instructions

Crypto-JS is a popular JavaScript library that is used for encrypting and decrypting data in web applications. It provides a number of cryptographic algorithms that can be used to secure data transmitted over a network or stored in a database. Some of the algorithms supported by Crypto-JS include AES, MD5, SHA-1, and RSA. It is easy to use and provides a simple interface for encrypting and decrypting data in your web applications.
Here is an example of how you might use Crypto-JS in a JavaScript application to encrypt and decrypt data:
// Encrypt the data using the AES algorithm with a secret key
var encryptedData = CryptoJS.AES.encrypt("My secret data", "mySecretKey");

// Decrypt the data using the same key
var decryptedData = CryptoJS.AES.decrypt(encryptedData, "mySecretKey");

// Convert the decrypted data from a CryptoJS object to a regular string

Hi Koushik
I am implementing this concept in Framework and there are multiple specs file in the spec folder but this encryption and decryption file is implemented in only one file
Could you please help me with the command to run the test by passing secret key as an argument

[shreyashtewari]

Hi koushik
I am not able to enter the Secret key through the terminal
It is showing error as the term SECRET_KEY is not defined.

Please help me with the same

[SamPrince]

Thanks for this. Another excellent and useful video - greatly appreciated.

The encrypted strings have a lot of characters in common which would usually ring alarm bells for me about the (lack of) pseudorandomness.

We've been using a text file sat outside of the project folder (in the user's profile/home directoryactually) to hold secrets, so they don't get shared around accidentally. That's fine when you all run locally on the same OS, but not as good if we did want to set up anything automated.

One way or another the secrets need to be stored somewhere though e.g. an environment variable or shell script like you've shown here. Presumably with github actions there's a safe place to store them? It doesn't feel like environment variables were designed to be highly secure places, but perhaps they are safe.

hi i want to automate vpn extention using selenium python how can do this please ???

[sagarsathyanarayanan]

how would you save a password as secret key if its running with the pipelines. Then providing the password through terminal is not possible

What if I am using this in simple JS via using cdn for crypto

I means i am trying to encypt the form data sending via ajax and in backend i am using node for decrypt that how i can do that?

I am able to encrypt in ajax but when i post that data via ajax in node then how i can decrypt that

[pradipvaghela]

when i do a code using type script it gives me the error in constructor(page). an erorr is "Parameter 'page' implicitly has an 'any' type, but a better type may be inferred from usage" and second is that, while using "this. page=page " it giving me error "Property 'page' does not exist on type 'LoginPage'.ts" for typescript. please give me the solution of this. thanks

Hey brother can you provide a solution for this error " Browser has been closed at obejct". while runinng a particular code of the module it's working properly. But, while running the whole script it failed and give an error " Browser has been closed at obejct". can you please assist me how to resolve this for my script.🙏

How can we encrypt the url using crypto can u please explain?

[kriparao]

Is this possible in browser environment as well (for my frontend) or only in the nodejs environment?

[maheshtekawade]

Using secret key anyone can get credentials right?
If yes, then how can we execute tests in Jenkins?
In Jenkins file we need to pass secret key with command.

[renitarenae]

Much needed video. But what can we do for Github actions? The run command on Github actions will carry the secret key know?

[ArunKumar-fqne]

Hello bro is there any solution this cryptojs to install python module

[smtabatabaie]

Is this possible to encrypt a data using another person's blockchain address (which is also their public key) in a way that they can only decrypt it using their own private key?

[dqhjtel]

Hi bro, I have been using cypress with js not ts. problem is it's showing error in "data: string" and "data.username" parts. cypress console throws error as : Cannot read properties of undefined (reading 'words')

[naveensingh]

How to handle this if our backend is in SpringBoot? Reply would be appreciated
