jscrypt

Encrypt/Decrypt your files with percentage progress and desired chunksize via Node.js built-in crypto and stream modules.

jscrypt is a very small and handy module for encrypting/decrypting files with selected speed and a progress callback.

NEW VERSION: Now It's possible to know when the job is done. Callback will return a boolean type,value of "true" to show the job is done.

npm install jscrypt --save

Module functions: var jscrypto = require('jscrypto'); jscrypto.encryptFile(sourceFile,destinationFile,algorithm,password,chunksize,callback); jscrypto.decryptFile(sourceFile,destinationFile,algorithm,password,chunksize,callback);

We assume that we want to encrypt file named "A.txt" with AES256 encryption algorithm, password "P@sW0rD" and by chunksize of 655000 bytes :

var jscrypto = require('jscrypto');

jscrypto.encryptFile("A.txt","A-encrypted.txt","aes256","P@sW0rD",655000,(progress) =>{

console.log(progress);

});

Now we want to decrypt file named "A-encrypted.txt" :

var jscrypto = require('jscrypto');

jscrypto.decryptFile("A-encrypted.txt","A-decrypted.txt","aes256","P@sW0rD",655000,(progress) =>{

console.log(progress);

});

New version feature: callback returns a boolean when job is done. For example:

jscrypto.encryptFile("A-encrypted.txt","A-decrypted.txt","aes256","P@sW0rD",655000,(isDone)=>{ if(isDone === true ) { console.log('Job is done!); } });

Notice: default chunksize is 665536. Whenever you prefer to use default chunksize, you should pass 0 to chunksize argument.
