VirtualKeyboard: hashes are regularly changing
The 'Banque Populaire' change its authentification system and now requires numeric passwords to be introduced with a virtual keyboard. The problem is that the image seems to be modified very quickly (so the hash is not the same and boobank complains on unfound symbols: Bug(banquepopulaire): Symbol '1' not found; all symbol hashes are available in /tmp/weboob_session_yC3nh9
Looking into /tmp/weboob_session_*, I find images of numbers. For sessions at a few seconds of distance, the files are the same. But after a few minutes, images changes. Looking at the images (convert 474bae7d...png -compress none toto1.pnm, ...) and comparing the pnm files, we can clearly see small differences between images without real visual differences. So it seems that BP tries to block number recognition with hashes :-(
I you want some example of images, just ask. But another way to find the number will probably have to be implemented. A call to an OCR software ?
