This is used for [[Amiibo]] key generation. 0x30-bytes are generated. The input buffer size must be 0x40-bytes. The content of the input buffer changes each time the [[Amiibo]] is written to.
This is used for [[Amiibo]] key generation. 0x30-bytes are generated. The input buffer size must be 0x40-bytes.
The input u8 must be either zero or non-zero, the used value varies depending on what crypto(AES/HMAC) operation is done after the crypto init.
