Cryptography

Supported platforms:
Available since: Gideros 2016.04

Description

Cryptographic primitives.

Example

<syntaxhighlight lang="lua"> local key = "GiderosGideros11" local iv = "GiderosRules2023" local paddingType = 1

local function cryptCopy(src, dst) local srcf = io.open(src, "rb") local dstf = io.open(dst, "wb") local size = 2^13 -- good buffer size (8K) while true do local block = srcf:read(size) if not block then break end block = Cryptography.aesEncrypt(block,key,iv,paddingType) dstf:write(block) end srcf:close() dstf:close() end

local function decryptCopy(src, dst) local srcf = io.open(src, "rb") local dstf = io.open(dst, "wb") local size = 2^13 + 16 -- good buffer size (8K + 16 for padding) while true do local block = srcf:read(size) if not block then break end block = Cryptography.aesDecrypt(block,key,iv,paddingType) dstf:write(block) end srcf:close() dstf:close() end

cryptCopy ("|D|myfile.sqlite", "C:/tmp/myfile.crypt") decryptCopy ("C:/tmp/myfile.crypt", "C:/tmp/myfile.sqlite") </source>

Methods Cryptography.aesDecrypt decrypts an AES string Cryptography.aesEncrypt encrypts a string with AES Cryptography.b64 Base64 encode some data Cryptography.md5 computes the MD5 hash of the input string Cryptography.unb64 Base64 decode a string
