Crate dcrypt_algorithms 

Cryptographic primitive implementations and adapters.

This crate provides implementations of various cryptographic primitives with explicit validation and zeroization boundaries. Constant-time behavior and no_std support are primitive- and feature-specific; the crate does not make blanket guarantees for either property.

Security Features

Relevant defensive patterns include:

• Secure memory handling with automatic zeroization
• Constant-time comparison operations
• Memory barrier utilities
• Secure operation patterns
