 +signed by wneriez. 
 +2. In the previously mentioned document designed by wneriez in April 2020
 +the date in its statements was mistakenly written as "April 15th, 2019", 
 +which was a typo, but cannot be changed due to the nature of digital signature. 
 +We declare that it's hereby corrected to "April 15th, 2020"
 +3. A new member, vimacs (0xEA2DB82FE04A9403) has became a new signer since this 
 +month. You can validate the new keys by cross-checking the other two copies of 
 +this document, signed by biergaizi and persmule. 
 +4. Due to the ongoing security issues of OpenPGP keyservers, it makes signature 
 +verification an issue and somewhat a challenge. For completeness, complete 
 +procedures for canary verification has been added. 
 +Canary Verification Procedures 
 +1. To verify biergaizi's signature... 
 +    a. Obtain the public key from any traditional OpenPGP Keyserver, such as 
 +, and import the public key. The fingerprint 
 +    is 0x255211B2395A5A3E0E48A0F1FAD3EB05E88E8D6D. 
 +    b. Use the latest GnuPG in any operating system. 
 +2. To verify persmule's signature... 
 +    a. Unfortunately, it's not possible yet. Recent attacks on OpenPGP key- 
 +    servers have raised great security concerns within the community, as a 
 +    countermeasure, persmule's new public key has been published to the 
 + keyserver, but without a User-ID. Currently, 
 +    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, and this 
 +    would effectively restore the level of confidence. You can archive the 
 +    documents to your own machine as soon as it's published to ensure no data 
 +    tampering has occurred. 
 +3. To verify vimacs' signature... 
 +    a. Due to the recent attacks on OpenPGP keyservers, vimacs has published 
 +    the OpenPGP public key to, again, without a User- 
 +    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' old public key from a traditional OpenPGP Keyserver, such 
 +    as, and import the public key. The fingerprint 
 +    is 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403. You should see an expired 
 +    public key. 
 +    d. Fetch vimacs' new public key from, using the same 
 +    fingerprint, and import the public key. You should see that the public 
 +    key has been updated. 
 +    e. Please note that the key is still shown as "expired" because the new key 
 +    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" warning (because the latest UID is 
 +    not published, only the expired UIDs are available).
