encryptjs

A library to encrypt and decrypt a string

usage:

      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, ciphered 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, ciphered text will be saved in your given file path as ".JSON" format

Available functions:

      encrypt(plaintext,secretkey,bit): To encrypt the string 
      decrypt(plaintext,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

Caveats: � getTextEncryptAndSaveToJSONFile (); will create a JSON file in the path provided. It will not append the JSON object in a file.
