-'''CommonETicket''' (for short, '''cetk''') is a format as a ticket used to store an encrypted titlekey (using 128-Bit AES-CBC). This format seems to be identical to DSi/Wii tickets.

-The Signature Type is the same const as that in [[TMD]]. The certificate chain is located at offset 0x2A4 for tickets from CDN/SOAP, however this cert-chain is removed once the ticket is installed to NAND.
-== Some facts==
-* '''CETK''' can be fetched through HTTP using the link to default update server, using the title's [[TMD]] URL where "cetk" is used instead of "tmd" for the URL. The 3DS NIM module retrieves system tickets via SOAP request ''GetCommonETicket''.
