stoken is a tokencode generator compatible with RSA SecurID 128-bit (AES) tokens. The project includes several components:

• A simple command line interface (CLI) used to manage and manipulate tokens
• A GTK+ GUI with cut&paste functionality
• A shared library allowing other software to generate tokencodes on demand

• libtomcrypt or nettle
• libxml2
• libgtk3.0 (required for stoken-gui only)

If you are building from Git, you'll need to install autoconf / automake / libtool, and run autogen.sh first. This is not necessary if building from a released source tarball.

On Debian or Ubuntu, this should satisfy most/all dependencies:

sudo apt-get install libgtk-3-dev libtomcrypt-dev libxml2-dev libtomcrypt-dev autoconf automake libtool build-essential

./configure
make
make install

First, import a token from a raw string or an "sdtid" XML file:

stoken import --token 2000123456...
stoken import --token com.rsa.securid.iphone://ctf?ctfData=2000123456...
stoken import --file mytoken.sdtid

This will prompt for an optional password, so that your seed is encrypted on disk.

Next, use the CLI or GUI to show the current tokencode:

stoken tokencode
stoken-gui &

If your token requires a PIN, stoken will prompt for it. You can use stoken setpin to cache your PIN in ~/.stokenrc. This is much less secure, but may be useful for automation.

Modern versions of OpenConnect link against libstoken and can send an autogenerated tokencode as the password. Import your token using the above instructions, then:

openconnect -u USERNAME --token-mode=rsa HOSTNAME

See the man pages for additional details: stoken(1), stoken-gui(1)

See examples/ and src/stoken.h for information on using the shared library interface (libstoken) to generate tokencodes from other applications.

stoken-gui	stoken-gui --small

As of v0.8, stoken can be built for Windows using the MinGW cross toolchain on Fedora. This is not tested or maintained regularly.

On a Fedora 20 PC (other versions may work as well), install the build dependencies:

yum groupinstall "Development Tools"
yum install git autoconf automake libtool mingw32-gnutls mingw32-libxml2 mingw32-gtk3

git clone git://github.com/cernekee/stoken
cd stoken
bash autogen.sh
mingw32-configure
make winpkg

If all goes well, you should be able to copy winpkg.zip to a Windows PC and run stoken.exe or stoken-gui.exe.

Several items are known to be missing or broken on the Windows build:

• Default home directory is probably incorrect
• No installer
• The GUI requires its assets to be in the current directory
• Password entry is not masked
• stoken --random flag
• No charset translation on filenames
