What is
it?
The axTLS
embedded SSL project is a highly configurable
client/server TLSv1 SSL 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 for details.

Features
|
A very small
footprint (around 50-60kB for the library
in 'server only' mode). |
|
Implements
TLSv1.0/1.1 |
|
Session
resumption for high SSL performance. |
|
AES128/AES256 for
high quality encryption (as well as RC4). |
|
Portable across
many systems (written in ANSI C). Tested
on Linux/Win32/Cygwin. |
|
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
(but supports v23 client hello). |
|
Anonymous or
Ephemeral DH. |
|
DSA or ECC. |
|
DES/3DES ciphers. |
|
Key generation
(however certificate generation is
supported). |
