Crate secure_gate 

Zero-cost secure wrappers for secrets — Fixed<T> for stack, Dynamic<T> for heap.

This crate provides explicit wrappers for sensitive data like CloneableArray, CloneableString, and CloneSafe, ensuring no accidental exposure. See README.md for usage and examples.

Modules

cloneable

Cloneable secret types (requires the zeroize feature). Provides wrappers that can be safely duplicated while maintaining security guarantees. Cloneable secret primitives for handling sensitive data that can be safely duplicated.

encoding

Encoding utilities for secrets (various encoding features available). Secure encoding/decoding with validation and zeroization. Encoding utilities for secure handling of encoded secret data.

random

Available macros (exported globally for convenience):

Macros
