- No dependency on
- Option to generate either the desktop (
VSST) or mobile (
VSMT) version on 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.
- 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.
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.
If you have
pip installed on your system, you can install them with
pip install lxml oath PyCrypto requests.

Provisioning a new VIP Access credential
This is used to create a new VIP Access token: by default, it stores
the new credential 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 -t TOKEN_MODEL, --token-model TOKEN_MODEL VIP Access token model. Should be VSST (desktop token, default) or VSMT (mobile token). Some clients only accept one or the other.
Here is an example of the output from
vipaccess provision -p:
Credential created successfully: otpauth://totp/VIP%20Access:VSST12345678?secret=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA&issuer=Symantec This credential expires on this date: 2019-01-15T12:00:00.000Z You will need the ID to register this credential: VSST12345678 You can use oathtool to generate the same OTP codes as would be produced by the official VIP Access apps: oathtool -d6 -b --totp AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA # 6-digit code oathtool -d6 -b --totp -v 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 VSST12345678 expiry 2019-01-15T12:00:00.000Z
Generating access codes using an existing credential
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.
