The card is largely ISO 7816 compliant, but does not provide any
simple way of listing the content which is supported by current
PKCS#15 implementation therefore the PKCS#15 emulator had to be
used.
The certificates are compressed in a similar way as in DNIE
cards which complicates reading from the card and which I think
could be moved to the shared ISO (or some other file since I saw
that code already many times).
The card supports wide range of algorithms including
RSA-PSS and RSA-OAEP padding schemes in-card. On the other hand,
it does not allow raw RSA and SHA1 hashes on card anymore.
The card is manufactured by Gemalto so it has strict ATR which
can be used for detection.
