+ | decision that can be verified by checking the warrant canary document in April, | ||

+ | We declare that it's hereby corrected to "April 15th, 2020". | ||

- | 5. We are looking for a solution. But for now, we decided that the best | + | Canary Verification Procedures |
- | option is starting publishing new canary documents using the new key. | + | ~~~~~~~~~~~~~~~~~~~~~~~~ |
- | As a temporary measure, you can check the canary documents signed by | + | |
- | biergaizi and wnereiz to decide the validity of the Statements. By signing | + | |
- | their own copies, it indicates that the new key has been verified privately | + | |

+ | a. Unfortunately, | ||
+ | servers have raised great security concerns within the community, as a | ||
+ | countermeasure, | ||
+ | https:// | ||
+ | it's impossible to import a OpenPGP public key without User-ID for a | ||
+ | 3rd-party to verify the canary document signed by persmule. | ||
+ | |||
+ | b. We are looking for a solution. But for now, you should check the | ||
+ | canary documents signed by biergaizi and vimacs to decide the validity | ||
+ | of the canary documents. This effectively reduced the number of signers | ||
+ | to two people. It reduces the level of confidence, but currently there is | ||
+ | no alternative option yet. | ||
+ | |||
+ | c. Once the technical problem of using a public key without User-ID is | ||
+ | resolved, you can check the previous signatures retroactively, | ||
+ | would effectively restore the level of confidence. You can archive the | ||
+ | documents to your own machine as soon as it' | ||
+ | tampering has occurred. | ||
+ | |||
+ | 3. To verify vimacs' | ||
+ | |||
+ | a. Due to the recent attacks on OpenPGP keyservers, vimacs has published | ||
+ | the OpenPGP public key to https:// | ||
+ | ID. But it's possible for a 3rd-party to verify the signatures by following | ||
+ | these steps. | ||
+ | |||
+ | b. Use Debian GNU/Linux operating system and install GnuPG. Other operating | ||
+ | systems may lack the necessary out-of-tree GnuPG patches required, Debian | ||
+ | must be used. | ||
+ | |||
+ | c. Fetch vimacs' | ||
+ | as https:// | ||
+ | is 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403. You should see an expired | ||
+ | public key. | ||
+ | |||
+ | d. Fetch vimacs' | ||
+ | fingerprint, | ||
+ | key has been updated. | ||
+ | |||
+ | e. Please note that the key is still shown as "expired" | ||
+ | has no UID associated. But you should be able to see a new, valid (not | ||
+ | expired) subkey by... | ||
+ | |||
+ | $ gpg --list-options show-unusable-subkeys --list-keys 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403 | ||
+ | |||
+ | f. Now, it's possible to verify the signature by following the standard | ||
+ | procedures. Ignore the "key expired" | ||
+ | not published, only the expired UIDs are available). | ||
