class Duende.IdentityModel.CryptoRandom
Assembly: Duende.IdentityModel
Inheritance: object → System.Random → CryptoRandom
A class that mimics the standard Random class in the .NET Framework - but uses a random number generator internally.
Methods
public static
byte[]
CreateRandomKey(int length)
Creates a random key byte array.
length
The length.
public
int
Next()
Returns a nonnegative random number.
Returns A 32-bit signed integer greater than or equal to zero and less than <see cref="F:System.Int32.MaxValue" /> .
public
int
Next(int maxValue)
Returns a nonnegative random number less than the specified maximum.
Returns A 32-bit signed integer greater than or equal to zero, and less than <paramref name="maxValue" /> ; that is, the range of return values ordinarily includes zero but not <paramref name="maxValue" /> . However, if <paramref name="maxValue" /> equals zero, <paramref name="maxValue" /> is returned.
maxValue
The exclusive upper bound of the random number to be generated. <paramref name="maxValue" /> must be greater than or equal to zero.
public
int
Next(int minValue,
int maxValue)
Returns a random number within a specified range.
Returns A 32-bit signed integer greater than or equal to <paramref name="minValue" /> and less than <paramref name="maxValue" /> ; that is, the range of return values includes <paramref name="minValue" /> but not <paramref name="maxValue" /> . If <paramref name="minValue" /> equals <paramref name="maxValue" /> , <paramref name="minValue" /> is returned.
minValue
The inclusive lower bound of the random number returned.
maxValue
The exclusive upper bound of the random number returned. <paramref name="maxValue" /> must be greater than or equal to <paramref name="minValue" /> .
public
double
NextDouble()
Returns a random number between 0.0 and 1.0.
Returns A double-precision floating point number greater than or equal to 0.0, and less than 1.0.
public
void
NextBytes(byte[] buffer)
Fills the elements of a specified array of bytes with random numbers.
buffer
An array of bytes to contain random numbers.
