=Command 0x04010084=

The input buffer size must be <=0x1E0-bytes, and the out buffer size must be >0 and <=0x20-bytes. This calculates a SHA256-HMAC over the input buffer using the current already-generated [[Amiibo]] HMAC key, the output hash is then written to the out buffer.

The input buffer size must be <=0x1E0-bytes, and the out buffer size must be >0 and <=0x20-bytes. This calculates a SHA256-HMAC over the input buffer using the current already-generated [[Amiibo]] HMAC key(generated_amiibodata+0x20), the output hash is then written to the out buffer.

=Command 0x04020082=

This is used for [[Amiibo]] key generation. 0x30-bytes are generated.

=Command 0x04030044=

This is used for the actual [[Amiibo]] AES crypto, max input buffer size is same as command 0x04010084. The AES mode used for this is the same as for Amiibo key generation. Normal-key = generated_amiibodata+0x0, IV/whatever = generated_amiibodata+0x10(see command 0x04010084 regarding generated_amiibodata).
