encryptjs

A library to encrypt and decrypt a string

usuage:

npm install encryptjs --save-dev in your project folder

Import the module using require command

var encrypt=require('encryptjs');

To encrypt the string , we need a plain text and a "secret key", the same "secret key" is used to decrypt the cipher text.

var secretkey='ios';
var plaintext='apple';
var cipherText =encrypt.encrypt(plaintext,secretkey,256);
console.log(cipherText+" ** ");
var decipher=encrypt.decrypt(cipherText,secretkey,256);
console.log("Deciphered Text is : "+decipher);

To get the string from console , encrypt & write to a text file :

var secretkey='ios';
var filePath="./encrypted.txt";
encrypt.getTextEncryptAndSaveToTextFile(filePath,secretkey,256);

Enter the text to be encrypted in console prompt, ciphred text will be saved in your given file path as ".txt" format

To get the string from console, encrypt & write to a JSON file :

var secretkey='ios';
var filePath="./encryptedData.JSON";
encrypt.getTextEncryptAndSaveToJSONFile(filePath,secretkey,256);

Enter the text to be encrypted in console.prompt, ciphred text will be saved in your given file path as ".JSON" format

Common method to decrypt the cipher text in both cases.

var decipher=encrypt.decrypt(cipherText,secretkey,256);


Available functions:

encrypt(plaintext,secretkey,bit): To encrypt the string
decrypt(ciphertext,secretkey,bit): To decrypt the string
getTextEncryptAndSaveToTextFile(filePath,secretkey,bit): Gets text from command line, encrypts & writes to Text file
getTextEncryptAndSaveToJSONFile(filePath,secretkey,bit): Gets text from command line, encrypts & writes to JSON file

Bit value can be 128, 192 & 256
