The MarshallSoft Delphi AES Library (AES4D) is a commercial component toolkit designed to help developers implement 256-bit Advanced Encryption Standard (AES) security into Windows applications built with Embarcadero Delphi. It provides a straightforward wrapper around optimized Win32 and Win64 DLLs, bypassing the need to write complex cryptographic math from scratch. Core Cryptographic Features
256-Bit Key Strength: Uses industry-standard Rijndael encryption to securely lock data.
Cipher Modes: Supports both Electronic Codebook (ECB) and Cipher Block Chaining (CBC) modes.
Data Verification: Includes built-in support for the SHA-256 cryptographic hash algorithm to verify data integrity.
Padding & Salts: Implements PKCS7 padding automatically to properly fill out partial data blocks.
Secure RNG: Features a cryptographically secure pseudo-random number generator for creating initialization vectors (IVs) and keys. Developer & Integration Benefits
Multi-Target Data Flexibility: Capabilities to encrypt and decrypt files, strings, or memory buffers with equal ease.
No Dependencies: The underlying engine relies strictly on core Windows API functions without requiring bulky external frameworks.
Thread Safety: The library functions are fully thread-safe, making it suitable for high-performance multi-threaded Delphi server apps.
Broad Delphi Support: Compatible with legacy versions from Delphi 3 all the way up through current modern Rad Studio / Delphi versions.
Royalty-Free Deployment: Once a developer license is purchased, the compiled aes32.dll or aes64.dll can be distributed with your applications without further licensing costs. Typical Use Cases in Delphi Apps
Local Database Security: Encrypting local database files (such as SQLite or absolute database tables) stored on client machines.
Secure File Transfer: Encrypting sensitive data payloads or proprietary configuration files before uploading them over local networks or standard channels.
Password and Key Management: Using the SHA-256 hash or AES functions to safely generate and handle app credentials.
