/**
|
|
* Provides a comprehensive set of classes for AES encryption and decryption,
|
|
* password-based key derivation, and secure content handling.
|
|
*
|
|
* <p>
|
|
* This package contains the core AES cryptographic components:
|
|
* <ul>
|
|
* <li>{@link AesCommon} — common AES utilities and base class for encryptors
|
|
* and decryptors</li>
|
|
* <li>{@link AesEncryptor} and {@link AesDecryptor} — stream-based AES
|
|
* encryption and decryption handlers</li>
|
|
* <li>{@link PasswordBasedAesEncryptor} and {@link PasswordBasedAesDecryptor} —
|
|
* AES implementations using password-derived keys (via PBKDF2)</li>
|
|
* <li>{@link SecretRandom} — abstract base class for secure byte sequence
|
|
* generators</li>
|
|
* <li>{@link SecretAesRandom} — deterministic AES-based implementation of
|
|
* {@code SecretRandom}</li>
|
|
* <li>{@link SecretDerivedAesParameters} — encapsulates derived AES keys and
|
|
* IVs with contextual integrity checks</li>
|
|
* <li>{@link SecretMultiRecipientCryptor} — supports encrypting data for
|
|
* multiple recipients using independent key derivation paths</li>
|
|
* <li>{@link SecretPassword} — immutable password container designed for secure
|
|
* handling and comparison</li>
|
|
* </ul>
|
|
*
|
|
* <p>
|
|
* The package also offers plain content wrappers for handling unencrypted data
|
|
* sources:
|
|
* <ul>
|
|
* <li>{@link PlainBytes} — wraps raw byte arrays as content sources</li>
|
|
* <li>{@link PlainString} — wraps UTF-8 strings as content sources</li>
|
|
* <li>{@link PlainFile} — treats file-based or URL-based content as input
|
|
* sources</li>
|
|
* </ul>
|
|
*
|
|
* <p>
|
|
* This package is designed around streaming APIs and centralized context-based
|
|
* cryptographic parameter management using the shared {@link conflux.Ctx}
|
|
* object. It facilitates secure encryption workflows with support for dynamic
|
|
* derivation, deterministic streams, and multi-party encryption use cases.
