ct-tools

Some Rust code for submitting a cert to all of Chrome's trusted CT logs and getting back the SCTs

Usage:

$ cargo run submit path/to/cert-or-chain.pem ....

If the argument is a chain (more than one certificate) ct-tools will submit that precise chain. If it is a single certificate, ct-tools will automatically build a chain using crt.sh.

Example:

❯❯❯ cargo run submit example-chain.pem
    Finished dev [unoptimized + debuginfo] target(s) in 0.0 secs
     Running `target/debug/ct-tools submit example-chain.pem`
Submitting example-chain.pem ...
Find the cert on crt.sh: https://crt.sh?q=96F82FADFE9B285A17FDD7E5B00BB31C7659EF44FB6B00B4C2C7EB08C78FE783

You can also use it to check if a certificate is already in CT, without submitting it:

❯❯❯ cargo run check example-chain.pem
    Finished dev [unoptimized + debuginfo] target(s) in 0.1 secs
     Running `target/debug/ct-tools check example-chain.pem`
example-chain.pem was already logged
