Encrypted key module - Password-based and key-based key derivation

This module provides types and operations for encrypting symmetric keys using various key derivation functions (KDFs).

Supported key derivation methods:

• HKDF: For deriving keys from high-entropy inputs (not passwords)
• PBKDF2: Password-based, widely compatible
• Scrypt: Memory-hard, resistant to GPU attacks
• Argon2id: Most secure for passwords (default)
• SSHAgent: An SSH agent's signature over the salt (needs an SshAgent)

The main components are:

• EncryptedKey: Encrypted symmetric key with derivation parameters
• KeyDerivationMethod: Enum of supported methods
• KeyDerivationParams: Union type for method-specific parameters
• Individual parameter types: HKDFParams, PBKDF2Params, ScryptParams, Argon2idParams, SSHAgentParams
