Secure Memory Library

Provides general purpose data structures and utilities used by multiple ViaDuck projects. Implemented with a focus on memory security and safety.

Features

  • BaseN: Generic en-/decoder for any base (e.g. Base64, Base16, Hex). Various pre-defined coders exist. User-defined coders for any alphabet can be created at compile-time.
  • Buffer:
    • Variable size heap binary memory buffer.
    • Convenience and safe methods to add, write, etc.
    • Automatic shredding of buffer data with random bytes after destruction.
    • Extensions: String.
  • Range: Wrapper object for binary regions (pointer + size).
  • SafeInt: Wrapper class for integral types with arithmetic operations protected against overflows.
  • SecureUniquePtr: Automatic shredding of std::unique_ptr memory with random bytes after destruction.
