## How to Securely Clear Sensitive Data Stored in a std::string?

Securely Clearing Sensitive Data in std::string

In application development, protecting sensitive data, such as passwords, is crucial. When using std::string to store such data, securely clearing the string after usage is vital.

The Issue:

Storing sensitive data as a char * array allows for the use of APIs like SecureZeroMemory to erase the data from memory. However, for std::string, finding an equivalent method is necessary.

Solution:

Although the initial plan was to create an allocator to securely zero out memory, it was discovered that for small values, the allocator might not be invoked. Therefore, using std::string for sensitive data storage is not recommended.

Alternative:

To securely store and clear sensitive data, a custom class tailored for this specific purpose can be implemented. This custom class would provide the necessary functionality to securely handle sensitive data.
