1//! Error types related to DEK generation and persistence.
2//!
3//! This module provides error types that may occur during Data Encryption Key (DEK)
4//! generation and storage operations. It includes errors for key generation,
5//! persistence operations, and CMK-related issues.

14/// - Insufficient entropy
15/// - Invalid key parameters
16/// - Algorithm-specific failures

31/// - General storage errors
