Used to store and retrieve a sensitive information in memory. This is not meant for at rest encryption.

sString.consume(secretTextBuffer);
const value: string = sString.value((buffer: Buffer): string => {
    const password: string = buffer.toString('utf8');
    // doSomething with the password
    // returns something of type <T>
    return testReturnValue;
});
