It has a built-in tool called Android KeyStore that can generate asymmetric keys and self-signed certificates for Android apps.

Android Studio is an integrated development environment (IDE) for creating Android applications that use NFC.

Keytool is a command-line tool from the Java Development Kit (JDK) that can be used to generate asymmetric keys and self-signed certificates, as well as import and export CA-signed certificates. OpenSSL is an open source software that can be used to create both symmetric and asymmetric keys, as well as self-signed and CA-signed certificates. Common tools for generating NFC security keys and certificates include OpenSSL, Keytool, and Android Studio.

Self-signed certificates are generated and signed by the device itself, while CA-signed certificates are issued and signed by a third-party CA. For instance, symmetric keys are shared between sender and receiver, while asymmetric keys are unique to each party. FIDO2 supports not only today’s two-factor authentication but also paves the way for eliminating weak password authentication, with strong single factor hardware-based authentication.Generating NFC security keys and certificates depends on the type and level of security desired. The Security Key Series helps organizations accelerate to a passwordless future by providing support for the FIDO2 protocol. It offers support for FIDO U2F and FIDO 2. The Security Key Series offers superior security by combining hardware-based authentication and public key cryptography to effectively defend against phishing attacks and eliminate account takeovers.
