base64-min

base64 (npm base64-min)

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.

Example:

var base64 = require('base64-min');

DOCS

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

encodeFile(file)

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 :

base64.encodeFile('original.png');

decodeToFile(str,filepath)

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') ;

encodeWithKey(str,key)

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	)

decodeWithKey(str,key)

• 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
