Returns a buffer to the specified size filled with random data, that can be used with the cryptographic technologies.
Remark: The returned buffer can be used as key for the encryption functions for example.
// Generate a 32-byte random key (256 bits)
RandomKey is Buffer = RandomCryptoBuffer(32)
// Encryption with the generated key
EncryptedMessage is Buffer = CryptStandard(MyMessage, RandomKey)
<Result> = RandomCryptoBuffer([<Buffer size>])
- Buffer filled with random data,
- Empty buffer if an error occurs.
<Buffer size>: Optional integer
Size (in number of bytes) of buffer to initialize (32 by default).
- The first call to the function can be quite long (one second or more if the size of buffer to initialize is important). Indeed, initializing the random mechanism is very complex.
- InitRandom has no effect on the result of RandomCryptoBuffer.
