TINY LITTLE MOOLTIPASS LIB

Simple C lib to communicate with a Mooltipass. Should be written entirely in C89 with only libusb as a dependency (also pkg-config for building)

Usage is simple and mostly asynchronous, although a few synchronous functions exist for ease of use where no user input on the device is required.

tlmpContext* ctx;
tlmpInitContext(&ctx);

tlmpSetConnectCallback(ctx, onConnect);

while(1)
{
    tlmpUpdateContext(ctx);
}

tlmpTerminateContext(&ctx);

void onConnect(tlmpContext* ctx, tlmpDevice* dev, int conn)
{
    if(conn)
    {
        tlmpRequestAuthentication(dev, "domain.com", onAuth);
    }
}

void onAuth(const char* login, const char* pass)
{
    // password only valid for the lifetime of this callback
    // login not guaranteed to be valid after this callback
}

The commands that the mooltipass understands are listed in src/include/tlmp_messageids.h. At this point the only ones used are: TLMP_MESSAGE_STATUS (0xB9) TLMP_MESSAGE_SETCONTEXT (0xA3) TLMP_MESSAGE_GETLOGIN (0xA4) TLMP_MESSAGE_GETPASSWORD (0xA5)

TODO:

• Implement credential storage (TLMP_MESSAGE_SETLOGIN TLMP_MESSAGE_SETPASSWORD)
• Implement Mooltipass version checking (TLMP_MESSAGE_VERSION)
• Implement data storage (TLMP_MESSAGE_SETDATACONTEXT TLMP_MESSAGE_ADDDATACONTEXT TLMP_MESSAGE_WRITEDATACONTEXT TLMP_MESSAGE_READDATACONTEXT)
  • Create sample SSH wrapper using mooltipass storage for keys
• Implement password generator based on Mooltipass random number generator (TLMP_MESSAGE_GETRANDOM)
• Far, far, far more things
