CryptoSys PKI Pro Manual

Wipe.String Method

Zeroise a StringBuilder.

Syntax

[C#]

public static bool String(
   StringBuilder sb 
)

[VB]

Public Shared Function String (
   sb As StringBuilder 
) As Boolean

Parameters

sb StringBuilder: StringBuilder to be wiped

Return Value

Boolean
true if successful; false if fails

Remarks

NB You can't wipe an ordinary string as they are immutable in C#, so store any sensitive string data in a StringBuilder.

Example

StringBuilder sbPrivateKey = Rsa.ReadPrivateKey("BobPrivRSAEncrypt.p8e", "password");
Console.WriteLine("Before Wipe.String, sbPrivateKey contains {0} characters.", sbPrivateKey.Length);
Wipe.String(sbPrivateKey);
Console.WriteLine("After Wipe.String, sbPrivateKey = [{0}]", sbPrivateKey.ToString());
// Before Wipe.String, sbPrivateKey contains 848 characters.
// After Wipe.String, sbPrivateKey = []
