Android Question How do I generate cryptographically secure pseudo-random bytes

[SMOOTSARA]

Hi
How can I use this php library in b4a?

random_bytes​

(PHP 7, PHP 8)
random_bytes — Generates cryptographically secure pseudo-random bytes

Description ¶​

random_bytes(int $length): string

https://www.php.net/manual/en/function.random-bytes.php

By setting up an api and calling it from your app. Which obviously is total nonsense.

The better question is probably something like "How do I generate cryptographically secure pseudo-random bytes, sort of like the function random_bytes in PHP?"

The obvious starting point would be the built-in java class: https://docs.oracle.com/javase/8/docs/api/java/security/SecureRandom.html

Beyond that others will need to help as I'm not familiar with in-line java or Library Wrapping.

Dim sr As SecureRandom
Dim b(1000) As Byte
sr.GetRandomBytes(b)

Encryption library. Also works in B4J and there is a similar API in B4i iEncryption library.
