Rebex HTTPS is an HTTP and HTTPS client library for .NET. It brings TLS 1.3, TLS 1.2, SNI, SHA-2, AES/GCM, ChaCha20/Poly1305 and other modern security-related features to legacy platforms.

Rebex HTTPS is designed as a drop-in replacement for HttpWebRequest / WebRequest, WebClient and can be used as an alternative SOAP web services transport layer.

Why Rebex HTTPS?

TLS 1.3 or TLS 1.2 on Windows XP, Windows 7, or Windows CE

Trying to download a file from the web or access a secure web service from your .NET Compact Framework application? Watch out for WebException. .NET CF's HttpWebRequest doesn't support TLS 1.3, TLS 1.2 or SHA-2 based certificates.

Rebex HTTPS implements modern TLS features on all supported platforms including .NET Compact Framework 3.5/3.9 (Windows Mobile 5/6, Windows CE, Pocket PC, Windows Embedded Compact) and .NET 2.0/3.0/3.5 (even on Windows Vista SP1 and Windows XP SP3 with plugins).

Rebex HTTPS supports the following TLS/SSL features:

TLS 1.3, 1.2, 1.1, or 1.0 on Windows 7 or higher
TLS 1.3, 1.2, 1.1, or 1.0 on Windows XP SP3 or higher
TLS 1.3, 1.2, 1.1, or 1.0 on legacy .NET Compact Framework 3.5/3.9
Elliptic Curve DSA (ECDSA) digital signature algorithm
RSA digital signature algorithm
Ed25519 digital signature algorithm
ML-DSA post-quantum digital signature algorithm
Elliptic Curve Diffie-Hellman (ECDH) key exchange
ML-KEM post-quantum key exchange
Modular Diffie-Hellman key exchange
AES/GCM ciphers
ChaCha20/Poly1305 ciphers
SHA-2 certificates and hashing algorithms
OCSP stapling
Server Name Indication (SNI) extension
Renegotiation Indication extension
And more...

Note: ECDSA, ECDH require a plugin on very old systems. ML-KEM requires a plugin unless running on Windows 11 25H2. ML-DSA requires a plugin unless running on Windows 11 25H2 or up-to-date Linux with .NET 10.

Drop-in secure WebRequest and WebClient replacement

Replace System.Net.WebRequest's standard HTTPS/HTTP request handler with Rebex implementation that supports modern security standards. Just call Rebex.Net.HttpRequestCreator.Register() and you are (almost) done. Both WebRequest and WebClient are supported. In many cases, there is no need to change your old code (except registering Rebex HTTPS).

Drop-in secure WebServices transport replacement

Easily replace the transport layer of SOAP web services with new, secure HTTPS implementation. In many cases, almost no changes to your old code are needed.

Additional features

Stand-alone HTTP/HTTPS client - WebClient object makes it simple to perform basic operations
X.509 client certificate authentication
ZLIB and Deflate compression
HTTP CONNECT and SOCKS4/SOCKS5 proxy support
Advanced communication logging
