Lua Requires Chilkat v9.5.0.65+

UN/EDIFACT Syntax Level A Encoding/Decoding

See more Encryption Examples

Demonstrates the "eda" encoding that can be used throughout Chilkat. Lua

local chilkat = require("chilkat")

local sb = chilkat.StringBuilder.new()
sb:append("The 5 men of 223rd St")
print(sb:get_as_string())

-- Encode the utf-8 byte representation of the string in the
-- UN/EDIFACT syntax level A character set.
sb:encode("eda", "utf-8")
print(sb:get_as_string())

-- EDA Output should be: BTME027FCF6CFARFI94JT6.)F(14KJ2U

-- Decode back to the original string.
sb:decode("eda", "utf-8")
print(sb:get_as_string())
print("----")

-- The following requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- The "eda" encoding can be used anywhere within Chilkat.
-- For example, with the Crypt2 API
local crypt = chilkat.Crypt2.new()
crypt.crypt_algorithm = "aes"
crypt.cipher_mode = "cbc"
crypt.key_length = 256
crypt.encoding_mode = "eda"

local ivHex = "000102030405060708090A0B0C0D0E0F"
crypt:set_encoded_iv(ivHex, "hex")
local keyHex = "000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F"
crypt:set_encoded_key(keyHex, "hex")

local encStr = crypt:encrypt_string_enc("The quick brown fox jumps over the lazy dog.")
-- The output is UN/EDIFACT syntax level A
print(encStr)

-- Now decrypt:
local decStr = crypt:decrypt_string_enc(encStr)
print(decStr)
