Lua Requires Chilkat v9.5.0.77+

Encode Integer to Hex or Base64 using N Bytes

See more Encryption Examples

Demonstrates how to write an integer to N bytes (little-endian or big-endian) and return the bytes in any encoding such as hex, base64, etc. Lua

local chilkat = require("chilkat")

local crypt = chilkat.Crypt2.new()

-- 1193046 decimal is equal to 0x123456 hex.
local value = 1193046

-- Write the integer in 8 bytes using little-endian byte-order and return as hex
local bLittleEndian = true
local s = crypt:encode_int(value, 8, bLittleEndian, "hex")
-- The output is: 5634120000000000
print(s)

-- Now use big-endian...
bLittleEndian = false
s = crypt:encode_int(value, 8, bLittleEndian, "hex")
-- The output is: 0000000000123456
print(s)

-- Instead of hex, get the 8 bytes using base64.
s = crypt:encode_int(value, 8, bLittleEndian, "base64")
-- The output is: AAAAAAASNFY=
print(s)
