Canary Issues

Post by Main Sequence » Sun Sep 27, 2020 3:43 pm

For people who are supposed to be experts in privacy and security, your warrant canary has a few issues!

Your canary is signed with the obsolete SHA-1 hash, which is now widely deprecated, because it is prone to hash collisions, meaning it is effectively BROKEN. It would only take a minor tweak to your config settings to use SHA-512 as your default hash algorithm.

Second, the version of PGP used to sign that Canary is: GnuPG v2.0.22 (GNU/Linux).

I find it interesting that you are still using such old, outdated software -- the 2.0 branch of GnuPG was end-of-life'd on December 31st, 2017 -- almost 3 full years ago!
GNU Privacy Guard - Wikipedia

Before the release of GnuPG 2.2 ("modern"), the now deprecated "stable" branch (2.0) was recommended for general use, initially released on November 13, 2006. This branch reached its end-of-life on December 31, 2017; Its last version is 2.0.31, released on December 29, 2017.

Thank you for addressing the issue I raised so promptly.

Hash: SHA512

As of September 29, 2020, cryptostorm has not received any National Security Letters or FISA court orders, and we have not been subject to any gag order(s) by a FISA court, or any other similar court(s) of
any government. cryptostorm has never placed any backdoors in our hardware or software and has not received any requests to do so. cryptostorm has never disclosed any user communications to any third par
ty. No searches or seizures of any kind have ever been performed on cryptostorm assets.

This canary will be updated quarterly, with the next update being December 31 in 2020.
After that, it will be updated on March 31 in 2021.
The updates will be performed manually, so the update might be off by a day or two at the most.

To verify this message, on the terminal import our public key from or any of the other popular keyservers:
$ gpg --keyserver --recv-key E9C7C942
gpg: requesting key E9C7C942 from hkp server
gpg: key E9C7C942: public key "cryptostorm support ( <>" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)
$ gpg2 --fingerprint E9C7C942
pub 4096R/E9C7C942 2015-01-22
Key fingerprint = 4D87 F984 A222 8392 57FE 36A5 BBDB 991A E9C7 C942

sub 4096R/E9F7009A 2015-01-22
$ gpg --verify canary.txt
gpg: Good signature from "cryptostorm support ( <>"

There will most likely be other lines in the output from that last command, but as long as it says "Good signature", the verification worked correctly.
