(Ruby) Encode Integer to Hex or Base64 using N Bytes

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.

require 'chilkat'

crypt = Chilkat::CkCrypt2.new()

# 1193046 decimal is equal to 0x123456 hex.
value = 1193046

# Write the integer in 8 bytes using little-endian byte-order and return as hex
bLittleEndian = true
s = crypt.encodeInt(value,8,bLittleEndian,"hex")
# The output is: 5634120000000000
print s + "\n";

# Now use big-endian...
bLittleEndian = false
s = crypt.encodeInt(value,8,bLittleEndian,"hex")
# The output is: 0000000000123456
print s + "\n";

# Instead of hex, get the 8 bytes using base64.
s = crypt.encodeInt(value,8,bLittleEndian,"base64")
# The output is: AAAAAAASNFY=
print s + "\n";
