A few +select users might already receive maliciously signed binaries that include a +backdoor. This is where siglog can help by adding transparency in the future. For each binary you can log a signed checksum that corresponds to that binary. If a signed checksum appears in the log that you did not expect: excellent, now -you know that your signing infrastructure was compromised at some point. Anyone -can also detect if a logged checksum is unaccounted for in your package -repository by inspecting the log. In other words, the claim that the same -binaries are published for everyone can be _verified_. +you know that your signing infrastructure was compromised at some point.

Honest mistakes can be detected. However, end-users need |
