16	GetTLSClientPrivk
17	GetTLSClientCert

Used for accessing data calibrated at the factory.

GetDeviceCert

Takes a type-0x16 output buffer with fixed size 0x180.

Returns the DeviceCert. This is identical to 3DS DeviceCert/CTCert besides the strings. NIM loads the DeviceId from this.

GetDeviceCert2

Takes a type-0x16 output buffer with fixed size 0x240.

Same as GetDeviceCert, except this returns more data and the data starts differing at offset 0x108 compared to GetDeviceCert.

GetTLSClientPrivk

Takes a type-0x16 output buffer with fixed size 0x134.

Returns a container-structure for the encrypted TLS client-privk. Decrypting this fails unless an unknown size >0x134 is passed to this setcal cmd?

Used by SSL-sysmodule, see here.

GetTLSClientCert

Takes a type-0x16 output buffer with fixed size 0x804.

Returns a container-structure for the plaintext TLS client-cert.

Used by SSL-sysmodule, see here.
