CryptRandomData()

Syntax

Result = CryptRandomData(*Buffer, Length)

Fills the specified memory buffer with random data from the cryptographic safe pseudorandom number generator.

Parameters

*Buffer	The buffer to fill.
Length	The size of the buffer in bytes.

Return value

Returns nonzero if the random data was generated successfully and zero otherwise.

Remarks

The generator has to be opened first with the OpenCryptRandom() command.

To generate random data from the faster but not cryptographic safe pseudorandom number generator, use the RandomData() function.

Example

  *Key = AllocateMemory(16)
  
  If OpenCryptRandom() And *Key
    CryptRandomData(*Key, 16)
    
    Text$ = "Generated Key:"
    For i = 0 To 15
      Text$ + " " + RSet(Hex(PeekB(*Key+i), #PB_Byte), 2, "0")
    Next i     
    
    CloseCryptRandom()
  Else
    Text$ = "Key generation is not available"
  EndIf
  
  MessageRequester("Example", Text$)
