base64 (npm base64-min)
Build Status Coverage Status
Disclaimer: For node versions < 4 use the 1.2.0 version.
This modules can be used to encoding & decoding messages (strings) and files using base64.
I'm trying to add new features based on other packages to get an all in one npm module. Actually base64-min can encode and decode: strings, files and strings with XOR encrytion.

Why use this module?

It's minimalist and focused in the best javascript performance.

Install base64-min module

At cmd, type:
$ npm install base64-min
or to install this package globally, use:
$ npm install -g base64-min

After install run unit tests

$ cd ./node_modules/base64-min/
$ npm install
$ npm test

Do you want a test report?

$ cd ./node_modules/base64-min/
$ npm install
$ npm test  --coverage

How to use?

To load module functionalities, you must use the require.js properties integrated in node.js.
var base64 = require('base64-min');


encode (str)
This method is used to encode a plain-text string to a encoded string in base64.
  • Arguments :
  • ``str`` - The string you want to encode.
  • ``type`` - Encoding Type (This argument is optional) | Available types: 'MIME'.
  • Result : Encoded string in base64.
  • Example :
base64.encode('base64-min npm module'); // result = YmFzZTY0LW1pbiBucG0gbW9kdWxl
base64.encode('base64-min npm module', 'MIME'); // result = YmFzZTY0LW1pbiBucG0gbW9kdWxl
                                                 // encoded string in base64, using MIME constraints
decode (str)
This method is used to decode a the base64 message to a plain-text string.
  • Arguments :
  • ``str`` - The message (in base64) you want to decode.
  • Result : Our message decoded in plain-text.
  • Example :
base64.decode('YmFzZTY0LW1pbiBucG0gbW9kdWxl'); // result = base64-min npm module
This method is used to encode files into base64 string.
  • Arguments :
  • ``file`` - The file path of the you want to encode.
  • Result : Encoded File into a string in base64.
  • Example :
This method is used to decode messages and save the result in one file (Tested and functional with PNG Files).
  • Arguments :
  • ``str`` - The message (in base64) you want to decode.
  • ``file`` - The file path of the you want to save.
  • Result : Decoded File
  • Example :
base64.decodeToFile('ZGF0YQ==', 'result.png') ;
This method is used to encode messages and encrypt messages using a key (XOR Encryption - Fast and "Secure").
  • Arguments :
  • ``str`` - The message in plain-text.
  • ``key`` - The key you want to encrypt your message.
  • Result : Encoded encrypted message in base64.
  • Example :
base64.encodeWithKey('base64-min npm module', 'victorfern91'); // result = FAgQEVlGSwgbABlfBgRDGQAWEwkX
                                                               //(in plain text is YFK_C	)
  • Arguments :
  • ``str`` - The message in base64.
  • ``key`` - The key used to encrypt this message.
  • Result : Deciphered message in plain-text.
  • Example :
//Decoding with wrong key
base64.decodeWithKey('FAgQEVlGSwgbABlfBgRDGQAWEwkX', 'npm module'); // result = zx}14)/}wew/k$.vdcly
//Decoding with correct key
base64.decodeWithKey('FAgQEVlGSwgbABlfBgRDGQAWEwkX', 'victorfern91'); // result = base64-min npm module
