Re: [Globalplatform-users] 2048 bits RSA keys

[Karsten O. <wid...@t-...>]

Hi,

in the phase install_for_install_and_make_selectable() it should happen
that an instance of the applet is created. If some constraints like the
required memory or instances of used algorithms are not satisfied, this
error can result.

Karsten
