-3Due to this key rollover, the October message was not signed by persmule. +1. To verify biergaizi's signature...
-This did/does not indicate a security incident, all of the statements above +
-were valid, and are still valid.+

-cryptographic information can be obtained from the keyserver, without any +
-User-IDCurrentlyit's impossible to import a OpenPGP public key without +
-User-ID to a standard GnuPG installation, as a result, it's not possible +
-for a 3rd-party to verify the canary document signed by persmule.+
  
-5We are looking for a solution. But for now, we decided that the best +    bUse the latest GnuPG in any operating system.
-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 +
-by them as valid.+
  
-6This effectively reduced the number of signers to two peopleIt reduces +2. To verify persmule's signature...
-the level of confidence, but currently there is no alternative option yet.+
  
-7Once the technical problem of OpenPGP public key without User-ID is +    aDue to the previous attacks on OpenPGP keyservers, persmule has published

-persmule's signature as soon as it'published to your own machine to +    User-ID. But since April 2013, we have developed a workaround, described 
-ensure no data tampering has occured.+    below.
  
-8Unlike persmulebiergaizi and wnereiz's signing keys are unchanged+    bObtain the dummy public key from any traditional OpenPGP Keyserver, 
-but the Key-IDs have been changed to its full fingerprint format in the +    such as https://keyserver.ubuntu.com, and import the public key. The 
-canary document for clarity.+    fingerprint is 0x7636112A33805777A0646B1BFA7C50B699AC61D2. Note thatto 
 +    import this key, one must copy and paste the key in ASCII from the Keyserver 
 +    website to a file or console and use the command "gpg --import". Due to a 
 +    technical problem, Using "gpg --recv-key" or "gpg --search-keys" does not 
 +    work.
  
-9When new information is available, it will be published in the "Special +    cThis is a special dummy public key with its User-IDs and subkeys stripped 
-Announcements" section in future warrant canary documents.+    that we specifically created, leaving only a "stub" User-ID (with an invalid 
 +    E-mail address, "Kikek <othar7ok@ep2quey.invalid>"). Its sole purpose is 
 +    allowing the subsequent import of additional subkeys. 
 + 
 +    d. Next, with the stub key already imported, obtain the public key from 
 +    https://keys.openpgp.org using the same fingerprint, and import this key. 
 +    Because the dummy key with its stub User-ID is already in presence, it's 
 +    now possible to import the https://keys.openpgp.org public key directly. 
 + 
 +    e. Use the latest GnuPG in most operating system, the signatures made by 
 +    persmule's key can now be verified as usual. 
 + 
 +3. To verify vimacs' signature... 
 + 
 +    a. Obtain the public key from any traditional OpenPGP Keyserver, such as 
 +    https://keyserver.ubuntu.com, and import the public key. The fingerprint 
 +    is 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403. 
 + 
 +    b. Use the latest GnuPG in any operating system.
