This toolset can be used to emulate a hardware token (with SHA256 seeds) and as to perform OTP verification and drift detection . The SHA-1 version of this tool is available here
emulates tokens with SHA-256 seeds (i.e. C203)
converts hex seed to base32 format
generates QR image based on hex or base32 seed key values
generates random seed values (i.e. for Token2 programmable tokens)
can verify the time drift with customizable skew value
We have also developed a fully client-side version of Token2 TOTP Toolset (Token2 TOTP Toolset - local), which can be run locally without accessing any libraries/resources on the Internet (including the QR image generation). The full source code of "Token2 TOTP Toolset - local" is available under our GitHub repository.

COVID19 Situation in Switzerland and France
Due to current preventive measures being taken against the COVID19 outbreak in Switzerland and France (such as border closures and potential lockdown of Geneva airport) we are expecting delays in shipping and delivery with both express delivery (Fedex/UPS) as well as the regular post In particular, as the office in France is currently not functioning, all orders placed on the EU website will be shipped from Switzerland instead.
