B4X

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.

Dim crypt As ChilkatCrypt2
crypt.Initialize("crypt")

'  1193046 decimal is equal to 0x123456 hex.
Dim value As Int = 1193046

'  Write the integer in 8 bytes using little-endian byte-order and return as hex
Dim bLittleEndian As Boolean = True
Dim s As String = crypt.EncodeInt(value, 8, bLittleEndian, "hex")
'  The output is: 5634120000000000
Log(s)

'  Now use big-endian...
bLittleEndian = False
s = crypt.EncodeInt(value, 8, bLittleEndian, "hex")
'  The output is: 0000000000123456
Log(s)

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