Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,When user asks GPG for\Nsignature generation,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,all those-- PNPG, GPG agents\Nand SG demo works together.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And today, our family\Ndemonstrates how those
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,processes interact.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And here is Ayumi-san.

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Yabuki-san will represent\NGPG user.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Because he daily uses GPG\Nas a Debian developer.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And she, she represents\NGPG. Her name is Ayumi.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,She's my daughter.\NShe represents GPG.

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,This time, this represent\Nthe nuke token.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,This metal box.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Yes?
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Actually, we have another\Nthing that is ping entry.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Today, this dumper baby\Nrepresent ping entry.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Yes, let's see.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, suppose a user\Nhave a file
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and he asks GPG to\Ngenerate signature

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, Yabuki-san asks her,\N"Please make signature."
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then she says, "Yes sir."
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then she generate cache\Nof the file.

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then she ask GPG agent.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,This represents\Npipe or socket.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So then usually she\Nhas a key in the file system.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,But today, as I represent here...
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Usually, the private key\Nis in here.

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,It's securely stored \Ninside a Gnuk token.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then GPG agent forwards\Na request to ST demo.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Actually, it is in Japanese\Nnow, but it is special
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,protocol between\NGPG agent and SG demo.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then SG demo asks passphrase\Nfor Gnuk token.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,But-- pass it here.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,She asks passphrase.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then ping entry spawned\Nfrom GPG agent.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then ping entry\Ngoes to user--
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,pops up windows to user,\Nand he asks passphrase.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Yes.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then, he knows the passphrase\Nback to GPG agent.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And the passphrase\Ngoes through GPG agent
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,to SG demo\Nthrough token.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then he shakes Gnu token.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then he generate signature.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then signature go back\Nthrough GPG agent
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and GPG.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And lastly GPG gives\Nsignature to user.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,That's an interaction\Nof how GPG works when
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,user asks generating\Na signature.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Thank you for\Nthe demonstration.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And thank you for\Nmy family and Yabuki-san.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,A little bit about Gnuk token.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,The Gnuk token is a \Nspecial hardware
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,dedicated for GnukPG,\Nand its specialty is,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,"I design and implement\Nthis for user's freedom."
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And the firmware is\Ncalled Gnuk.

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,The reason why implement\Nand I put my info on
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Gnuk token is that to control\Nour crypto computation.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And my purpose is to\Nminimize the attack surface
