<method name="get_entropy">

<description>
Generates a [PackedByteArray] of cryptographically secure random bytes with given [param size].
[b]Note:[/b] Generating large quantities of bytes using this method can result in locking and entropy of lower quality on most platforms. Using [method Crypto.generate_random_bytes] is preferred in most cases.
