SecureBlackbox (VCL) by /n software is a comprehensive software development kit designed to embed robust data protection, secure storage, and encrypted transfer directly into Delphi and C++Builder applications. Built as a clean-room implementation free of external dependencies, it gives VCL developers precise control over complex cryptographic processes.
The top 5 security features of SecureBlackbox for VCL applications are detailed below. 1. Comprehensive TLS 1.3 & Secure Network Communication
SecureBlackbox provides full client and server-side support for TLS 1.3 and optimized TLS 1.2 protocol implementations.
Native Socket Integration: The VCL edition features specialized descendant classes that drop seamlessly into standard Delphi sockets (TClientSocket/TServerSocket) as well as third-party suites like Indy, ICS, Synapse, and RealThinClient.
Protocol Ecosystem: Beyond basic sockets, it features turnkey security implementations for standard internet protocols, allowing you to deploy secure SFTP, SSH2, FTPS, HTTPS, and REST clients or servers.
Advanced Routing Security: It includes native support for modern safety protocols like DNS over TLS to prevent traffic intercept tampering. 2. Advanced PKI and Certificate Validation Management
Managing an internal Public Key Infrastructure (PKI) can be error-prone, but the suite includes a dedicated PKIBlackbox system designed to process complex trust hierarchies.
Deep Chain Verification: The framework manages unified certificate chain validations and supports deep cryptographic tree processing capable of verifying nested countersignatures or timestamps.
Revocation Checking: It exposes easy-to-configure Online Certificate Status Protocol (OCSP) and Timestamping (TSP) servers to instantly check if certificates remain valid.
Trusted Service Lists (TSLs): The architecture inherently validates official government or enterprise Trusted Service Lists to secure highly-regulated international compliance pipelines. 3. Standards-Compliant Document & Data Signing
For legally binding transactions and non-repudiation, SecureBlackbox includes native support for advanced European and international digital signature standards.
XAdES, CAdES, PAdES, and ASiC: Developers can create tightly structured signatures for XML documents (XAdES), binary messages (CAdES), PDF files (PAdES), and Associated Signature Containers (ASiC).
Pre-Sign Editing: Advanced components allow documents (such as PDFs or Office files) to be safely opened, structured, or modified in an “editing mode” internally before finalizing the signature block. 4. Hardware Security Module (HSM) & Cloud Vault Integration
To protect cryptographic assets against memory scraping or theft, SecureBlackbox isolates private cryptographic keys from standard application memory.
PKCS#11 Token Interaction: It allows VCL apps to natively interact with physical hardware security modules (HSMs), smart cards, and USB Crypto Tokens via PKCS#11 and KMIP protocols.
Cloud Storage Vaults: It offers built-in connectors to securely fetch and store operational certificates inside cloud repositories like Microsoft Azure Key Vault. 5. Distributed Cryptography (DCAuth) for Remote Signing
Distributed Cryptography addresses the security risks associated with sharing raw private keys across a network by keeping sensitive keys isolated on secure endpoints.
