CryptographyGetRandomKey Method

Creates a random key of random length.

Definition

Namespace: InnerDrive.Core
Assembly: InnerDrive.Core (in InnerDrive.Core.dll) Version: 5.2.9017.0
C#
public static string GetRandomKey(
	int minLength,
	int maxLength
)

Parameters

minLength  Int32
The length in bytes of the shortest key to return.
maxLength  Int32
The length in bytes of the longest key to return.

Return Value

String
A String containing a random key of the appropriate length.

Remarks

This method uses a cryptographically strong random number generation algorithm. To create the highest likelihood that the returned key is unique, no processing is done on the key once it's generated.

The key is not guaranteed to be unique, but it is extraordinarily unlikely that two keys will be the same. The method uses two different methods to generate random numbers: a weak method, to get the key length, and a strong method to generate the actual key. This increases the likelihood that the key will be unique.

Exceptions

ArgumentExceptionThrown if minLength is smaller than MinKeyLength or maxLength is greater than MaxKeyLength.
