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. | |||

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. | |||
