The SmartCard-HSM 4K MicroSD card combines 8GB of Flash memory with an
embedded secure element. The device is suitable for mobile and IoT
devices. Drivers for Windows, Linux and Android are available. The
embedded secure element contains the SmartCard-HSM software, supporting
RSA, ECC and AES keys as well as sophisticated key management mechanisms.
Important note: The MicroSD card does not support RSA keys with 4096
bits due to length constraints in the communication channel.
