What is it?
The axTLS embedded SSL project is a highly configurable client/server TLSv1.2 library
designed for platforms with small memory requirements. It comes with a
small HTTP/HTTPS server and additional test tools. Download
To run it
 | Go to the axTLS directory and type "make". Select the
appropriate OS and then run it
(as superuser, from the _stage directory) with: |
| ./axhttpd |
| Point your browser at https://127.0.0.1 (or whatever your server name is). |
| You will be asked to accept the axTLS certificate (press ok). |
| You can access the same pages using normal HTTP on
http://127.0.0.1. |
| On the demo you can run the axssl server followed by the axssl
client. Type a few characters into the client and see them appear on the
server (on Linux/Unix you can type characters from the server and see
them on the client). |
See the README for notes, changes and
errata. Some countries have export restrictions on cryptography
software. Check here

Features
| A very small footprint (around 50-60kB for the library in
'server only' mode). |
| Supports TLSv1.2/1.1/1.0 |
| Session resumption for high SSL performance. |
| AES128/AES256 for high quality encryption. |
| SHA256/SHA384/SHA512 for high quality digests. |
| Portable across many systems (written in ANSI C). Tested on
Linux/Win32/Cygwin. |
| Variable RSA key sizes (512-4096 bits have been tested). |
| A very simple API - ~20 functions in C and no structures. |
| Peer client/server verification, certificate chaining, session
renegotiation. |
| X509v1, PKCS#8, PKCS#12 keys/certificates in DER/PEM format, |
| Highly configurable compile-time options (using
BusyBox-like config tool) |
| Partial openssl compatibility. |
| Interfaces for C#, VB.NET, Java, Perl and Lua. |
| It's free! (BSD style licensing) |
Not supported
| SSLv2 or SSLv3. |
| Anonymous or Ephemeral DH. |
| DSA or ECC. |
| DES/3DES/RC4 ciphers. |
| Key generation (however certificate generation is supported). |
