Detailed Description
Source of random numbers.
QCA provides a built in source of random numbers, which can be accessed through this class. You can also use an alternative random number source, by implementing another provider.
The normal use of this class is expected to be through the static members - randomChar(), randomInt() and randomArray().
- Examples
- randomtest.cpp.

Constructor & Destructor Documentation
◆ Random() [1/2]
Standard Constructor.
- Parameters
-
provider the name of the provider library for the random number generation
◆ Random() [2/2]
QCA::Random::Random | ( | const Random & | from | ) |
Copy constructor.
- Parameters
-
from the Random object to copy from
Member Function Documentation
◆ nextByte()
uchar QCA::Random::nextByte | ( | ) |
Provide a random byte.
This method isn't normally required - you should use the static randomChar() method instead.
- See also
- randomChar
- Examples
- randomtest.cpp.
◆ nextBytes()
SecureArray QCA::Random::nextBytes | ( | int | size | ) |
Provide a specified number of random bytes.
This method isn't normally required - you should use the static randomArray() method instead.
- Parameters
-
size the number of bytes to provide
- See also
- randomArray
- Examples
- randomtest.cpp.
◆ operator=()
Assignment operator.
- Parameters
-
from the Random object to copy state from
◆ randomArray()
|
static |
Provide a specified number of random bytes.
- Parameters
-
size the number of bytes to provide
- Examples
- randomtest.cpp.
◆ randomChar()
|
static |
Provide a random character (byte)
This is the normal way of obtaining a single random char (i.e. 8 bit byte), as shown below:
If you need a number of bytes, perhaps randomArray() may be of use.
- Examples
- randomtest.cpp.
◆ randomInt()
|
static |
Provide a random integer.
This is the normal way of obtaining a single random integer, as shown below:
- Examples
- randomtest.cpp.
