Cryptography

AES Encryption

All forms of AES are supported. If you find this confusing, it is. Feel free to ask for help if you do not understand or can't seem to get it to work.

These examples should be enough, but its Crypto. It isn't easy!

local aes = NoName.Utils.AES


-- Load and execute your encrypted data from a file

aes.LoadScriptAES256CBC(filepath, password, iv)

-- Run encrypted data that is in a string variable. usefull if you are reading the data from a remote server.

aes.RunScriptAES256CBC(data, password, iv)

A more general example:

local sha = NoName.Utils.sha
local aes = NoName.Utils.aes

# AES 
local iv = {0x1, 0x2, 0x3, 0x1, 0x2, 0x3, 0x1, 0x2, 0x3, 0x1, 0x2, 0x3, 0x1, 0x2, 0x3, 06}
local rawfile = ReadFile("/scripts/testme.lua")

local lomes = aes.encrypt("password", rawfile, aes.AES256, aes.CBCMODE, iv)
WriteFile("/scripts/aes256.aes", lomes, false)
print("Lomes::", lomes)

--print("Decrypted:", aes.decrypt("password", lomes, aes.AES256, aes.CBCMODE, iv))

-- RunScriptAES256CBC assumes that your starting folder is /scripts/
aes.RunScriptAES256CBC("aes256.aes", "password", iv)

# SHA 
print ('HMAC Inforamtion')
print (sha.sha256(rawfile)) 
print (sha.hmac_sha256('thisisakey', 'thisissometext'))

Formats supported are:

    AES128,
    AES192,
    AES256,
    --
    ECBMODE,
    CBCMODE,
    OFBMODE,
    CFBMODE,
    CTRMODE,

SHA & SHA256 Encryption

Nice utility for securing files and file versions etc. If you struggle to get this working or have an issue getting it sorted, please ask for help.

local sha = NoName.Utils.sha
local aes = NoName.Utils.aes

# AES 
local iv = {0x1, 0x2, 0x3, 0x1, 0x2, 0x3, 0x1, 0x2, 0x3, 0x1, 0x2, 0x3, 0x1, 0x2, 0x3, 06}
local rawfile = ReadFile("/scripts/testme.lua")

local lomes = aes.encrypt("password", rawfile, aes.AES256, aes.CBCMODE, iv)
WriteFile("/scripts/aes256.aes", lomes, false)
print("Lomes::", lomes)

--print("Decrypted:", aes.decrypt("password", lomes, aes.AES256, aes.CBCMODE, iv))

-- RunScriptAES256CBC assumes that your starting folder is /scripts/
aes.RunScriptAES256CBC("aes256.aes", "password", iv)

# SHA 
print ('HMAC Inforamtion')
print (sha.sha256(rawfile)) 
print (sha.hmac_sha256('thisisakey', 'thisissometext'))

JSON

Json Library for handling of handling Converting JSON text to/from Lua Table

local json = NoName.Utils.JSON

local data = {user = "user", pass = "pass"}

local encoded = json.encode(data)
local decoded = json.decode(encoded)

print(encoded)
DevTools_Dump(decoded)
DevTools_Dump(data)
