-Code-signing private key notes
-==
-
-The private keys for these certificates were generated on Gavin's main work machine,
-following the certificate authority's recommendations for generating certificate
-signing requests.
-
-For OSX, the private key was generated by Keychain.app on Gavin's main work machine.
-The key and certificate is in a separate, passphrase-protected keychain file that is
-unlocked to sign the Bitcoin-Qt.app bundle.
-
-For Windows, the private key was generated by Firefox running on Gavin's main work machine.
-The key and certificate were exported into a separate, passphrase-protected PKCS#12 file, and
-then deleted from Firefox's keystore. The exported file is used to sign the Windows setup.exe.
-
-Threat analysis
---
-
-Gavin is a single point of failure. He could be coerced to divulge the secret signing keys,
-allowing somebody to distribute a Bitcoin-Qt.app or bitcoin-qt-setup.exe with a valid
-signature but containing a malicious binary.
-
-Or the machine Gavin uses to sign the binaries could be compromised, either remotely or
-by breaking in to his office, allowing the attacker to get the private key files and then
-install a keylogger to get the passphrase that protects them.
-
-Threat Mitigation
---
-
-"Air gapping" the machine used to do the signing will not work, because the signing
-process needs to access a timestamp server over the network. And it would not
-prevent the "rubber hose cryptography" threat (coercing Gavin to sign a bad binary
-or divulge the private keys).
-
-Windows binaries are reproducibly 'gitian-built', and the setup.exe file created
-by the NSIS installer system is a 7zip archive, so you could check to make sure
-that the bitcoin-qt.exe file inside the installer had not been tampered with.
-However, an attacker could modify the installer's code, so when the setup.exe
-was run it compromised users' systems. A volunteer to write an auditing tool
-that checks the setup.exe for tampering, and checks the files in it against
-the list of gitian signatures, is needed.
-
-The long-term solution is something like the 'gitian downloader' system, which
-uses signatures from multiple developers to determine whether or not a binary
-should be trusted. However, that just pushes the problem to "how will
-non-technical users securely get the gitian downloader code to start?"
