This is a library of memory allocators and data structures to handle sensitive information, especially when interfacing with foreign and unsafe code.

It currently features:

• An interface to the system’s page allocator,
• a simple memory allocator implementing the Allocator trait, and
• access‐guarded wrappers around Box, Vec and String.

Add this to your Cargo.toml:

[dependencies]
sensitive = "0.10"

The force-mlock feature may be used to force allocations to be memory‐resident: If the memory cannot be locked, the allocation will fail. Without this feature, locking is attempted, but failures are ignored.

This code relies heavily on experimental nightly‐only APIs.
