CryptoSys API is a comprehensive developer’s toolkit designed to provide fast, lightweight, and highly efficient symmetrical cryptographic functions for server and desktop applications. Developed by DI Management Services, it is built specifically as a robust, native Win32/X64 DLL that runs independently of third-party external runtimes like OpenSSL.
The toolkit allows developers to incorporate enterprise-grade symmetric data encryption, hashing, and message authentication directly into backend server systems, automated scripts, and web applications. Key Technical Capabilities
Symmetric Encryption & Ciphers: Supports industry-standard block ciphers like AES-128/192/256, Triple DES (3DES), and Blowfish, alongside high-performance stream ciphers such as ChaCha20, Salsa20, and ArcFour (RC4).
Authenticated Encryption (AEAD): Offers secure Authenticated Encryption with Additional Data (AEAD) schemes like AES-GCM and ChaCha20-Poly1305 to ensure both data confidentiality and cryptographic integrity.
Advanced Hash Functions: Built-in support for the full suite of SHA algorithms, including older legacy formats and modern standards like SHA-224/256/384/512 and SHA-3 (including SHAKE and Keccak).
Message Authentication & MACs: Includes implementations of HMAC, CMAC, KMAC, and the Poly1305 one-time authenticator.
Key Derivation Functions: Robust functions for securely transforming passwords into cryptographic keys using PBKDF2 and the memory-hard SCRYPT algorithm.
Lightweight Implementations: Features cutting-edge, ultra-lightweight cryptographic suites like the ASCON cipher suite. Language Support & Integration
The API is designed for widespread server-side ecosystem compatibility. It provides native language interfaces and wrappers for a broad variety of environments: Backend Languages: C/C++, C#, and Python.
Enterprise & Legacy Systems: Visual Basic .NET (VB.NET/VB20xx), VB6, ASP, and VBA for automation inside Microsoft Access, Excel, and Word. Architectural Advantages for Servers
Completely Independent: It functions entirely independent of Microsoft’s built-in CryptoAPI (CAPI/CNG) and explicitly avoids using OpenSSL, protecting your server stack from shared library vulnerabilities.
Thread-Safe: The native DLL is completely thread-safe, making it suitable for multi-threaded, high-concurrency server deployments.
Self-Checking Security: Automatically triggers cryptographic self-checks for software integrity and operational key functions every time the library starts up.
No Deployment Overhead: It compiles into a direct, standard Windows DLL. It does not use COM or ActiveX components, meaning it requires no complex system registration (RegSvr32) during server provisioning.
For public-key (asymmetric) algorithms like RSA or ECDSA, or to manage X.509 digital certificates on your server, the tool is designed to pair directly with its sister product, CryptoSys PKI Pro.
