Corona HTML5 Crypto Plugin

Corona HTML5 Crypto Plugin similar to standard crypto lib. Includes additional encryption methods.

👷 Built with Corona HTML5 Node Kit.

Install

Add crypto_js.js and crypto.lua to the root of your project.

Require

local crypto = require("crypto")

API

digest

Generates the message digest (the hash) of the input string.

crypto.digest( algorithm, data [, raw] )

Arguments

name	description	type	required
algorithm	A constant specifying the hashing algorithm (see Constants).	Constant	Y
data	The input string.	String	Y
raw	Set to true for binary output, or false for hexadecimal string (default).	Boolean	N

Example

local crypto = require( "crypto" )
local hash = crypto.digest( crypto.md5, "Corona HTML5 Rocks!" )
print( hash )   --> b34ce2675b10580bf9f0d6018c72579c

hmac

Computes HMAC (Key-Hashing for Message Authentication Code) of the string and returns it.

crypto.hmac( algorithm, data, key [, raw] )

Arguments

name	description	type	required
algorithm	A constant specifying the hashing algorithm (see Constants).	Constant	Y
data	The input string.	String	Y
key	String to use as the seed for the HMAC generation.	String	Y
raw	Set to true for binary output, or false for hexadecimal string (default).	Boolean	N

Example

local crypto = require( "crypto" )
local hash = crypto.hmac( crypto.md5, "Corona HTML5 Rocks!", "SomeKey" )
print( hash )   --> 1341b82ca266c77f77b27a318508a481

Encryption

encrypt

Encrypts a string value using a passphrase. Defaults to AES cipher.

crypto.encrypt( data, passphrase [, cipher] )

Arguments

name	description	type	required
data	The input data to encrypt.	String	Y
passphrase	The passphrase string.	String	Y
cipher	A constant specifying the cipher to use. Defaults to AES. (see Constants).	Constant	N

Example

local crypto = require( "crypto" )
local encrypted = crypto.encrypt( "Corona HTML5 Rocks!", "passphrase" )
print( encrypted )   --> U2FsdGVkX19YaYWtxaJQJZ9LYoIFsCJS7pLF5vjHs+Q9v0c8evHoGWJ1dbYsUOKG

decrypt

Decrypts an encrypted value using a passphrase. Defaults to AES cipher.

crypto.decrypt( data, passphrase [, cipher] )

Arguments

name	description	type	required
data	The input data to decrypt.	String	Y
passphrase	The passphrase string.	String	Y
cipher	A constant specifying the cipher to use. Defaults to AES. (see Constants).	Constant	N

Example

local crypto = require( "crypto" )
local decrypted = crypto.decrypt( "U2FsdGVkX19YaYWtxaJQJZ9LYoIFsCJS7pLF5vjHs+Q9v0c8evHoGWJ1dbYsUOKG", "passphrase" )
print( decrypted )   --> Corona HTML5 Rocks!
