connect crypto utils

Install

    npm install connect-crypto

query decryptor

decrypt predefined url parameters and reassigns the decrypted value to request.query

var queryDecryptor = require('connect-crypto').queryDecryptor;

var mypassword = '123123Foo';

// the server
var server = connect()		
        .use(connect.query())		
        .use(queryDecryptor('p', mypassword)) // decrypt any url that has ?p=encryptedData (will turn to ?p=decryptedData)
        .listen(3000);	


// the server
var server = connect()		
        .use(connect.query())		
        .use(queryDecryptor(['p1', 'p2'], mypassword)) // several querystring params can be decrypted 
        .listen(3000);	
    

further customization can be achieved by supplying an options object:

var options = {
    algorithm: 				which algo is used for encyption/decryption, defaults to 'aes192'

    debug: 					debug mode will write errors from decipher.final() to console and alert if 
                            query middleware isn't installed

    decryptedDataEncoding:	encoding used to output decrypted data - must be the same encoding used in 
                            the encyption process - defaults to 'ascii'

    encryptedDataEncoding: 	encoding used for encrypted data - defaults to 'base64'	
};

connect()
    .use(connect.query())		
    .use(queryDecryptor('p', mypassword, options));

when using the options object, one may specify only a subset of the above options
