stoken is an open source tokencode generator compatible with RSA SecurID 128-bit (AES) tokens. It is a hobbyist project, not affiliated with or endorsed by RSA Security.
stoken offers the following interfaces:
Newer (but experimental) Ubuntu packages are often available from my PPA. Sample usage:
sudo -s apt-get install python-software-properties add-apt-repository ppa:cernekee/ppa apt-get update apt-get install stoken libstoken-dev
Updates and releases will be posted here at stoken.sf.net
Android users: check out Easy Token, which is based on libstoken.
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
