A free software implementation of Symantec’s VIP Access application and protocol

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.

Sad to know it’s completely usable in Authy and other TOTP authenticators except for the provisioning part.
