Overview

Encryption options for RAR5 archives

This model configures password-based encryption using AES-256-CBC with PBKDF2-HMAC-SHA256 key derivation.

Examples:

Enable encryption with default settings

options = EncryptionOptions.new(
  enabled: true,
  password: "SecurePassword123"
)

Custom KDF iterations

options = EncryptionOptions.new(
  enabled: true,
  password: "SecurePassword123",
  kdf_iterations: 524_288  # 2^19, higher security
)
