StreamSec Tools is a native cryptographic library for Embarcadero Delphi ^TM - TLS 1.3, SSH and SFTP, X.509/PKIX and CMS, and post-quantum algorithms - written entirely in Object Pascal and compiled straight into your application. No OpenSSL DLLs, no Windows CryptoAPI, no FFI layer: one self-contained stack you can read, debug and ship as a single executable, on every platform your Delphi code targets.

WHY DEVELOPERS CHOOSE IT

• It compiles into your EXE. No libssl/libcrypto to ship or version, no DLL conflicts, and your patch story is "rebuild" - not chasing OpenSSL CVEs across customer installs. Why not just link OpenSSL?
• Current, and proven by interop. TLS 1.3 (mutual TLS, 0-RTT, OCSP stapling, KeyUpdate) and post-quantum key exchange, each interop-tested against OpenSSL and OpenSSH. TLS · SSH
• One coherent stack. TLS, X.509/PKIX, CMS/S-MIME, OCSP and SSH/SFTP under one API and one vendor - plus the SNIF secure remoting framework. See StreamSec Tools 4.x
• Cross-platform, one codebase. The same crypto on Win32/Win64, macOS, Android and iOS - no per-platform TLS backend to wrangle.
• Yours to audit. Full Object Pascal source, built by your own compiler; the linker pulls in only what you use.
