This is a fork of cyrozap/python-vipaccess. Main differences:
- No dependency on
qrcodeorimagelibraries; you can easily use external tools such asqrencodeto convert anotpauth://URI to a QR code if needed, so it seems unnecessary to build in this functionality. - Option to generate either the mobile (
SYMC/VSMT) or desktop (SYDC/VSST) versions of the VIP Access tokens; as far as I can tell there is no real difference between them, but some clients require one or the other specifically. There are also some rarer token types/prefixes which can be generated if necessary (reference list from Symantec) - Command-line utility is expanded to support both token
provisioning (creating a new token) and emitting codes for an
existing token (inspired by the command-line interface of
stoken, which handles the same functions for RSA SecurID tokens
python-vipaccess is a free and open source software (FOSS) implementation of Symantec's VIP Access client (now owned by Broadcom).
If you need to access a network which uses VIP Access for two-factor authentication, but can't or don't want to use Symantec's proprietary applications—which are only available for Windows, MacOS, Android, iOS—then this is for you.
As @cyrozap discovered in reverse-engineering the VIP Access protocol (original blog post), Symantec VIP Access actually uses a completely open standard called Time-based One-time Password Algorithm for generating the 6-digit codes that it outputs. The only non-standard part is the provisioning protocol used to create a new token.

For development purposes, you can install the dependencies with pip install -r requirements.txt in
the project root directory.
To install pip see the pip installation documentation.
Install with pip3 to automatically fetch Python
dependencies. (Note that on most systems, pip3 invokes the Python 3.x version, while pip invokes
the Python 2.7 version; Python 2.7 is still supported, but not recommended because it's nearing
obsolescence.)
# Install latest release from PyPI
$ pip3 install python-vipaccess
# Install latest development version from GitHub
$ pip3 install https://github.com/dlenski/python-vipaccess/archive/HEAD.zip
This is used to create a new VIP Access token. It connects to https://services.vip.symantec.com/prov and requests a new token, then deobfuscates it, and checks whether it is properly decoded and working correctly, via a second request to https://vip.symantec.com/otpCheck.
By default it stores the new token in the file .vipaccess in your home directory (in a
format similar to stoken), but it can store to another file instead,
or instead just print out the "token secret" string with instructions
about how to use it.
usage: vipaccess provision [-h] [-p | -o DOTFILE] [-t TOKEN_MODEL]
optional arguments:
-h, --help show this help message and exit
-p, --print Print the new credential, but don't save it to a file
-o DOTFILE, --dotfile DOTFILE
File in which to store the new credential (default
~/.vipaccess)
-i ISSUER, --issuer ISSUER
Specify the issuer name to use (default: Symantec)
-t TOKEN_MODEL, --token-model TOKEN_MODEL
VIP Access token model. Often SYMC/VSMT ("mobile"
token, default) or SYDC/VSST ("desktop" token). Some
clients only accept one or the other. Other more
obscure token types also exist:
https://support.symantec.com/en_US/article.TECH239895.html
Here is an example of the output from vipaccess provision -p:
Generating request...
Fetching provisioning response from Symantec server...
Getting token from response...
Decrypting token...
Checking token against Symantec server...
Credential created successfully:
otpauth://totp/VIP%20Access:SYMC12345678?secret=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA&issuer=Symantec&algorithm=SHA1&digits=6
This credential expires on this date: 2019-01-15T12:00:00.000Z
You will need the ID to register this credential: SYMC12345678
You can use oathtool to generate the same OTP codes
as would be produced by the official VIP Access apps:
oathtool -b --totp AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA # output one code
oathtool -v -b --totp AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA # ... with extra information
Here is the format of the .vipaccess token file output from
vipaccess provision [-o ~/.vipaccess]. (This file is created with
read/write permissions only for the current user.)
version 1
secret AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
id SYMC12345678
expiry 2019-01-15T12:00:00.000Z
Once you generate a token with vipaccess provision, use vipaccess uri to show the otpauth:// URI and
qrencode to display that URI as a QR code:
$ qrencode -t UTF8 'otpauth://totp/VIP%20Access:SYMCXXXX?secret=YYYY&issuer=Symantec&algorithm=SHA1&digits=6'
Scan the code into your TOTP generating app, like FreeOTP or Google Authenticator.
The vipaccess [show] option will also do this for you: by default it
generates codes based on the credential in ~/.vipaccess, but you can
specify an alternative credential file or specify the OATH "token
secret" on the command line.
usage: vipaccess show [-h] [-s SECRET | -f DOTFILE]
optional arguments:
-h, --help show this help message and exit
-s SECRET, --secret SECRET
Specify the token secret on the command line (base32
encoded)
-f DOTFILE, --dotfile DOTFILE
File in which the credential is stored (default
~/.vipaccess
As alluded to above, you can use other standard OATH-based tools to generate the 6-digit codes identical to what Symantec's official apps produce.
