title: memory safety for encrypted, sensitive data
body: <p>im writing a server in c++ that will handle safe connections where sensitive data will be sent.</p>
  
  <p>the goal is never saving the data in unencrypted form anywhere outside memory, and keeping it at a defined space in the memory (to be overwritten after its no longer needed)</p>
  
  <p>will allocating a large chunk of memory and using it to store the sensitive data be sufficient and ensure that there is no leakage of data ?</p>
