WebCryptographic algorithms are most commonly used in smart cards. The chip ensures security by checking cardholder credentials (typically a PIN code) and performing cryptographic operations. Very simple in term of architecture, these cards were initially embedded with the algorithm and an 8-bit core, running at few tens of megahertz. how do you get tabs back on microsoft edge
