 + 
 +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 personal User-ID han bees published to the 
 +    https://keys.openpgp.org/ keyserver, but without 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 solution. But for nowyou 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 OpenPGP 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 keyserversvimacs has published 
 +    the OpenPGP public key to https://keys.openpgp.org, 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 necessary out-of-tree GnuPG patches required, Debian must 
 +    be used.
