Crate dcrypt_algorithms 

Cryptographic primitives library with constant-time implementation

This crate provides implementations of various cryptographic primitives with a focus on constant-time operations and resistance to side-channel attacks. The library is designed to be usable in both std and no_std environments.

Security Features

This library implements comprehensive security patterns to protect sensitive cryptographic material, including:

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