I wanted to make retrieval of data difficult to some extent, if the device ends up in the wrong hands. So the data had to be encrypted. So the solutions discussed in this post may not be the best in terms of protecting the data. You can use different cipher algorithms like AES. DES etc. In the above API, the first argument to encrypt function is text data you want to encrypt, e. The second argument is a secret phrase also called passPhrase.

This could be any text. Secret phrase is the key that is used to encrypt the data. Most server-side applications generate a key and store it in a secure location on the server and use that key to encrypt data. However my application is a mobile application written in JavaScript, so it would be very easy to find the secret key if someone really wants to — by looking at the JS source code.

So I decided to ask user to enter secret key along with password at the time of registration and subsequent login attempts. Using the secret key I encrypt the password and store it in the local database. Subsequently login operation requires user to enter password as well as the same secret key she had entered at the time of registration. The problem with this approach is that user has to remember secret key along with the password.

Once the data is hashed, you cannot retrieve it in its original form. For the password example above, I could hash the password that user entered at the time of registration and store in the database.

When user enters password at the time of login, I would hash it and compare the hashed value with the one stored in the database. Coming back to the encrypt function, the value it returns is not a string, but an object.

However you can store string representation of this object by calling toString and use it in decrypt function. Together they are used to encrypt the data. And these values change each time you call encrypt function with the same arguments see demo at the end of this post.

Decrypt function is also very easy to use. Try out following demo. Enter data to be encrypted and secret key and click Encrypt button.This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption.

Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications. A native implementation of TLS in Javascript and tools to write crypto-based and network-heavy webapps.

This library works in ActionScript as well. The unique feature of this library is asynchronous processing. A heavyweight process such as bit RSA key generation will be done asynchronously so that this library does not cause problems such as freezing browsers, "slow-downing" warning dialogs, etc. Cifre is a fast crypto toolkit for modern client-side JavaScript.

This is done by taking the best crypto code for js on the net and updating it to use modern technologies. There are plans to collaborate with the forge project.

One more to the list: Clipperz. And what does it even mean best one?

Encryption and Decryption using Crypto-js in Angularjs and Vector

Is it the most audited implementation? Does it uses a recommended algorithms? Does it have the simplest API? Having only one contributor and using some semi secret Russian algo similar to DES I would be surprised if it won't be one of the least recommended library out of the list provided here.

SJCL Is probably the only js library that was actually created by cryptography professionals. Don't know if it makes it the "best" but I wouldn't consider using any other 3rd party library in anything important. I have created a Repo with this info so people can help easily. Also the list has a new format that I think will help us to compare the different options easily: JavaScript Crypto Libraries Comments, missing libs and pull requests more than welcome.

Can anyone point me to actual security analysis on any of these crypto libraries? Which ones have been cracked?

How secure are these libraries to things like cache timing attacks? Which are considered the best, and why? I'm actually trying to move away from SJCL because the maintainer has abandoned the project and it doesn't play well with CommonJS require statements under some architectures. I looked for security analysis of SJCL and I couldn't find any, other than an offhand mention of a known vulnerability to cache timing attacks.

Why do people trust crypto-js? Because the authors at Google would never do evil? They don't even host the code anymore, and the docs are minimal to say the least. Tectract Sorry but there is no such info you request.

Take a look of a new list I did based in this one, but added some data about the libraries that will help you to evaluate them: JavaScript Crypto Libraries. I want to share with CryptoBench. Can i get a library which implement RSA.

Has a method that get secret and generate keypair and it simply implement encryption, decryption, signing and verifying.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again.

In this version Math. Such as IE 10 or before or React Native. The move of using native secure crypto module will be shifted to a new 4. As it is a breaking change the impact is too big for a minor release. The usage of the native crypto module has been fixed. The import and access of the native crypto module has been improved. For this reason CryptoJS might does not run in some JavaScript environments without native crypto module. Such as IE 10 or before. If it's absolute required to run CryptoJS in such an environment, stay with 3.

Encrypting and decrypting stays compatible. But keep in mind 3.

JavaScript library of crypto standards. JavaScript Branch: develop. Find file.JavaScript implementations of standard and secure cryptographic algorithms. CryptoJS is a growing collection of standard and secure cryptographic algorithms implemented in JavaScript using best practices and patterns.

They are fast, and they have a consistent and simple interface. If you have a problem with CryptoJS, if you want to discuss new features, or if you want to contribute to the project, you can visit the CryptoJS discussion group. MD5 is a widely used hash function. It's been used in a variety of security applications and is also commonly used to check the integrity of files.

Though, MD5 is not collision resistant, and it isn't suitable for applications like SSL certificates or digital signatures that rely on this property. SHA-1 is the most established of the existing SHA hash functions, and it's used in a variety of security applications and protocols. Though, SHA-1's collision resistance has been weakening as new attacks are discovered or improved.

It isn't as widely used as SHA-1, though it appears to provide much better security. SHA-3 is the winner of a five-year competition to select a new cryptographic hash algorithm where 64 competing designs were evaluated.

SHA-3 can be configured to output hash lengths of one of,or bits. The default is bits. The hash algorithms accept either strings or instances of CryptoJS. A WordArray object represents an array of bit words. The hash you get back isn't a string yet. It's a WordArray object. When you use a WordArray object in a string context, it's automatically converted to a hex string. You can convert a WordArray object to other formats by explicitly calling the toString method and passing an encoder.

Keyed-hash message authentication codes HMAC is a mechanism for message authentication using cryptographic hash functions. HMAC can be used in combination with any iterated cryptographic hash function. PBKDF2 is a password-based key derivation function. In many applications of cryptography, user security is ultimately dependent on a password, and because a password usually can't be used directly as a cryptographic key, some processing is required.

A salt provides a large set of keys for any given password, and an iteration count increases the cost of producing keys from a password, thereby also increasing the difficulty of attack. It was selected after a 5-year process where 15 competing designs were evaluated.This quick angular tutorial help to encrypt and decrypt variable using crypto. I am using Angularjs Crypto angular plugin for encryption and decryption. You can create encrypted string using your salt code so that user could not decrypt your data.

Normally programmer are using BASE64 string which can decrypt easily without any effort because they are using same salt or algorithm not user defined. There are a lot of online website providing functionality to decrypt BASE64 string. So both party have same public key salt to encrypt and decrypt data. Step 1: Include all necessary library files in header of index.

Step 3: We will create angularjs application controller file and inject all dependency including crypto. Here we configured crypto using. We have defined base64 salt and vector on-load of angular application. We have passed source string and encrypted using AES algorithm. You can see that i am using CryptoJS. You can send this encrypted data in request to server. You can decrypt this data using CryptoJS. First of all You need to create cypher params using encrypted ciphertext and then pass this cypher params with vector string to crypto-js decrypt method.

Your encryption key is visible to anyone by downloading your angular files.

To start, Execute the following command:. The above command will create a new package. To install the dependency, execute the following from the command line:. Finally, we need to start build our project. We have all necessary files to be used while making this. When we need to Encrypt or Decrypt our data. Also we define above that we going to use aescbc algorithm method. Now, if we want to encrypt a JavaScript object on disk. If we wanted to do this synchronously, we would look at the encrypt function below:.

In the above coed, we define that we want to use an AES algorithm. Because we want to save to a file, we want to create a buffer from our plaintext data. After we call cipher. In the above function we are reading the file into a buffer, decrypting it with the AES algorithm, and returning the decrypted object back to the user. You just saw how to encrypt and decrypt data with the Node. You will get all fileswhen you download the source code.
