-their own copiesit indicates that the new key has been verified privately + 
-by them as valid.+    ​a. Obtain the public key from any traditional OpenPGP Keyserversuch as 
 +    https://​,​ 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 
 +    https://​​ keyserver, but without a User-ID. Currently, 
 +    ​it'​s impossible to import ​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 documentsThis effectively reduced the number of signers 
 +    to two people. It reduces the level of confidencebut 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 https://​,​ 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 https://​,​ and import the public key. The fingerprint 
 +    is 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403. You should see an expired 
 +    public key.

 +    key has been updated.
-7Once the technical problem of OpenPGP public ​key without User-ID ​is +    ePlease note that the key is still shown as "​expired"​ because the new key
