~~The ECDSA public key for this cert is calculated from the ECDSA private key initialized by bootrom.~~ Boot ROM decrypts [[OTP]] and writes the private key and Nintendo's signature of ~~this certificate~~ to [[ITCM]]; the public key is computed from the private key.

Boot ROM decrypts [[OTP Registers]] and writes the private key and Nintendo's signature of CTCert to [[Memory_layout#ARM9_ITCM|ARM9 ITCM]]; the public key is computed from the private key.

The curve used for ECDSA is sect233r1.
