Module keys 

Cryptographic key types with secure memory handling.

This module provides key types that ensure sensitive key material is:

• Zeroized on drop to prevent memory leaks
• Never exposed in debug output
• Compared in constant time to prevent timing attacks

Security

All key types in this module are designed with defense-in-depth:

• SecretKey does not implement Clone to prevent accidental duplication
• Debug output is redacted to prevent logging of key material
• Comparison uses constant-time algorithms

Structs

SecretKey

A 32-byte secret key with automatic zeroization.

Enums

SecretKeyError

Errors related to secret key operations.

Constants

SECRET_KEY_LEN

The length of a secret key in bytes.
