+# Offline Signing
+
+Offline signing involves
+
+* Creating an unsigned transaction on a view-only wallet
+* Moving the unsigned transaction to an offline machine
+* Signing the unsigned transaction on an offline wallet
+* Moving the signed transaction to a view-only wallet
+* Broadcasting the transaction
+
+It is securer than a hardware wallet connected to an online computer via a USB
+cable. It is also more versatile than a hardware wallet.
+
+## Creating a new offline wallet
+
+Constructing a new offline wallet is done by executing
+
+```
+monero-wallet-cli --generate-new-wallet /path/to/wallet-file
+```
+
+on an offline machine. Record the seed on paper by executing `seed` on the
+offline wallet.
+
+## Creating a new offline wallet with seed offset passphrase
+
+Seed and seed offset passphrase combine to create a new seed. You can store seed
+and seed offset passphrase in separate places so that a thief can't steal your
+fund without stealing seed and seed offset passphrase. I recommend 6 to 8
+(english) words as a seed offset passphrase as one english word has 11 bits of
+entropy on average and 8 words have 88 bits of entropy. With seed passphrase,
+you can also create decoy wallets that contain a little bit of money and can
+protect you from torturers or blackmailers who demand money from you.
+
+If you want to create an offline wallet with seed and seed passphrase,
+create an offline wallet, record the seed on paper, delete the wallet file,
+generate seed offset passphrase, record seed offset passphrase on paper, and
+execute
+
+```
+monero-wallet-cli --generate-new-wallet /path/to/wallet-file \
+---restore-deterministic-wallet
+```
+
+to restore from seed and seed offset passphrase. When you restore from seed, you
+can enter seed offset passphrase. 
+
+Generate seed offset passphrase on an offline machine or with diceware because
+humans are bad at creating random passphrases.
+
+If you want to reconstruct an existing offline wallet that received or sent
+transactions, you need extra steps. Refer to `Restoring offline wallet`.
+
+## Creating a new view-only wallet
+
+To create a view-only wallet, copy primary address and secret view key from an
+offline wallet to an online machine where a view-only wallet is going to be
+created. You can get primary address by executing `address` on an offline wallet
+and secret view key by executing `viewkey` on the offline wallet.
+
+You can use a microSD card and two USB microSD card readers to exchange data
+between an offline wallet and a view-only wallet. You can also use a USB flash
+drive.
+
+To create a view-only wallet on an online machine, execute
+
+```
+monero-wallet-cli --generate-from-view-key /path/to/wallet-file \
+--daemon-address remote-node-address:port
+```
+
+If you want to reconstruct an existing view-only wallet that received or sent
+transactions, refer to `Restoring view-only wallet`.
+
+## Launching offline wallet
+
+Execute
+
+```
+monero-wallet-cli --wallet-file /path/to/wallet-file
+```
+
+## Launching a view-only wallet
+
+Execute
+
+```
+monero-wallet-cli --wallet-file /path/to/wallet-file \
+--daemon-address remote-node-address:port
+```
+
+It's safe to sync your wallet over clearnet. If you want to broadcast a
+transaction without revealing your IP address, execute
+
+```
+monero-wallet-cli --wallet-file /path/to/wallet-file \
+--daemon-address tor-or-i2p-remote-node-address:port \
+--proxy 127.0.0.1:tor-or-i2p-port
+```
+
+Synchronizing wallet over clearnet is a lot faster than doing it on tor or i2p.
+Thus, consider synchronizing over clearnet even if you broadcast transactions
+over tor or i2p.
+
+## Offline transaction signing
+
+Execute any wallet command that transfers monero to any address. For example,
+
+```
+transfer xmr-address amount-of-xmr-to-send
+```
+
+Any transfer command on a view-only wallet creates `unsigned_monero_tx` in the
+current working directory.
+
+Move `unsigned_monero_tx` to an offline machine that has an offline wallet.
+Execute
+
+```
+sign_transfer
+```
+
+on the offline wallet in the directory with `unsigned_monero_tx`.
+`signed_monero_tx` file is created in the current working directory. Move
+`signed_monero_tx` to the online machine with a view-only wallet. In the
+directory with `signed_monero_tx`, launch the view-only wallet, and execute
+
+```
+submit_transfer
+```
+
+Because a view-only wallet doesn't have key images, it can't see outgoing
+transactions. To make a view-only wallet see outgoing transactions, it has
+to export new outputs created by `submit_transfer` to an offline wallet which
+creates key images out of new outputs.
+
+Execute
+
+```
+export_outputs outputs
+```
+
+on a view-only wallet. Move `outputs` file to the offline machine with an offline
+wallet. Launch the offline wallet, and execute
+
+```
+import_outputs /path/to/outputs
+```
+
+Export key images derived from new outputs by executing
+
+```
+export_key_images key_images
+```
+
+on an offline wallet. Move `key_images` file to the machine with a view-only
+wallet. Launch the view-only wallet, and execute
+
+```
+import_key_images /path/to/key_images
+```
+
+## Updating wallet softwares on an offline signing machine
+
+When you update an offline machine with offline wallets, you can't just
+connect the machine to the internet and update wallet softwares because
+doing so exposes offline wallets to the internet.
+
+Instead, boot OS installation media, wipe filesystems, and then connect
+to the internet, and install everything from scratch again.
+
+If your root filesystem is encrypted, OS installation media can connect
+to the internet from the beginning because encrypted data are safe until
+they are decrypted.
+
+## Restoring offline wallet
+
+After updating wallet softwares on an offline signing machine by wiping it out
+and reinstalling everything, you have to restore offline wallet.
+
+Restore an offline wallet from seed (and seed offset passphrase) by executing
+
+```
+monero-wallet-cli --generate-new-wallet wallet-file --restore-deterministic-wallet
+```
+
+The new offline wallet can't sign new transactions because it doesn't have
+all trasaction outputs that precede a new unsigned transaction. Thus, it first
+has to import all outputs from a view-only wallet.
+
+On a view-only wallet that was derived from the offline wallet, execute
+
+```
+export_outputs all all_outputs
+```
+
+`all` is important because `export_outputs` exports only new outputs that weren't
+exported before, but
+
+```
+export_outputs all
+```
+
+exports all outputs. Move `all_outputs` file to the offline machine with the
+offline wallet. Execute
+
+```
+import_outputs /path/to/all_outputs
+```
+
+on the new offline wallet.
+
+## Restoring view-only wallet
+
+If you reconstruct view-only wallet, because it doesn't have key images,
+it can't see outgoing transactions. If it can't see outgoing transactions,
+it reports wrong account balances. Thus, it has to import all key images
+from its corresponding offline wallet.
+
+On the offline wallet, execute
+
+```
+export_key_images all all_key_images
+```
+
+`export_key_images` doesn't work because it exports only new key images that
+weren't exported before.
+
+```
+export_key_images all
+```
+
+exports all key images. Move `all_key_images` file to the machine with the
+view-only wallet. Execute
+
+```
+import_key_images /path/to/all_key_images
+```
