In most cases, Elliptical Curve Digital Signature Algorithm (ECDSA) provides double the performance of a 2K RSA key. Supported curves are secp521r1 (P-521), secp384r1 (P-384), and secp256r1, also known as prime256v1 (P-256). Keys¶. The following keys are used by the secure boot process: “secure bootloader key” is a 256-bit AES key that is stored in Efuse block 2. The bootloader can generate this key itself from the internal hardware random number generator, the user does not need to supply it (it is optionally possible to supply this key, see Re-Flashable Software Bootloader). This is the “print the key id of the given certificate” option. This is a hash of the public key of the given certificate. It identifies the key uniquely, remains the same on a certificate renewal and depends only on signed fields of the certificate. certificate-pubkey option. This is the “print certificate’s public key” option.
