| Output IV / CTR: this is the IV/CTR which would be used if the crypto operation were to continue.

~~For CBC mode, the output MAC is the last 16-bytes of the ciphertext. For the other modes, this field is the same as the input IV/CTR.~~

| Support for this keytype was added with the NATIVE_FIRM updated with [[2.2.0-X]]. When the running NATIVE_FIRM doesn't support this keytype, the result is the same as using keytype7. This is used by the ~~friends~~ module.

| Used by the [[Friend_Services|the friends module]] for [[Friend_Services#Approach_Contexts|ApproachContext]] encryption. See [[FRDU:GetMyApproachContext]].

| This is used by the NFC module.

Support for this keytype was added with the NATIVE_FIRM updated with [[9.3.0-21|9.3.0-X]]. When the running NATIVE_FIRM doesn't support this keytype, the result is the same as using keytype7. Before selecting this keyslot, Process9 writes a keyY from the Process9 .(ro)data section(keydata is different for retail/dev units) to this keyslot. Once finished with crypto, Process9 restores the original keyY to this keyslot.
