OpenSSL 3.6 Build Documentation

Welcome to the beginner documentation for building OpenSSL 3.6 from source.

What is OpenSSL?

OpenSSL is an open-source library for:

Encryption - AES, ChaCha20 and more
Digital Signatures - RSA, ECDSA, ML-DSA (Post-Quantum)
Certificates - X.509, PKI infrastructure
TLS/SSL - Secure network communication

Version 3.6 brings Post-Quantum Cryptography:

ML-DSA (formerly Dilithium) - NIST FIPS 204
ML-KEM (formerly Kyber) - NIST FIPS 203

Quick Start

# 1. Install prerequisites (one-time)
winget install Microsoft.VisualStudio.2022.Community
winget install StrawberryPerl.StrawberryPerl
winget install NASM.NASM
 
# 2. Start build
powershell.exe -ExecutionPolicy Bypass -File "build_openssl.ps1"
 
# 3. Verify result
openssl version -a
