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.

Note: This example requires Chilkat v9.5.0.77 or greater.

let crypt = chilkat::Crypt2::new();

// 1193046 decimal is equal to 0x123456 hex.
let value = 1193046;

// Write the integer in 8 bytes using little-endian byte-order and return as hex
let mut b_little_endian = true;
let mut s = crypt.encode_int(value, 8, b_little_endian, "hex").unwrap_or_default();
// The output is: 5634120000000000
println!("{}", s);

// Now use big-endian...
b_little_endian = false;
s = crypt.encode_int(value, 8, b_little_endian, "hex").unwrap_or_default();
// The output is: 0000000000123456
println!("{}", s);

// Instead of hex, get the 8 bytes using base64.
s = crypt.encode_int(value, 8, b_little_endian, "base64").unwrap_or_default();
// The output is: AAAAAAASNFY=
println!("{}", s);
