Module encryption_layer 

Storage Encryption Layer

Provides a simple XOR-based encryption layer for block storage. This is for demonstration/educational purposes — not production cryptography.

Supports two cipher modes:

• Xor: Repeating key XOR
• XorWithNonce: XOR with a key derived from nonce + base key

Structs

EncryptedBlock

An encrypted block with metadata.

EncryptionLayerConfig

Configuration for the encryption layer.

EncryptionLayerStats

Statistics for the encryption layer.

StorageEncryptionLayer

Storage encryption layer providing XOR-based encryption for blocks.

Enums

CipherMode

Cipher mode for the encryption layer.
