-1. Since mid-October, persmule's old signing key 0x2987A25DAC8454A5 has +None. 
-expired. A new key, 0xEDFFE248ECFACDE3C805906804A40D21DBB89B60, has been + 
-created and uploaded to https://keys.openpgp.org/, it can be obtained from +Canary Verification Procedures 
-this keyserver.+~~~~~~~~~~~~~~~~~~~~~~~~ 
 + 
 +1. To verify biergaizi's 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 0x255211B2395A5A3E0E48A0F1FAD3EB05E88E8D6D. 
 + 
 +    b. Use the latest GnuPG in any operating system. 
 + 
 +2. To verify persmule's signature...
  
-2. The new key will be used by persmule to sign future warrant canary +    a. Due to the previous attacks on OpenPGP keyservers, persmule has published 
-documents. You can verify the signature by crosschecking the other two +    the OpenPGP public key to https://keys.openpgp.org without a User-ID. Using 
-documents signed by biergaizi and wnereiz for consistency.+    the standard method, it's impossible to import a OpenPGP public key without 
 +    User-ID. But since April 2013, we have developed a workaround, described 
 +    below.
  
-3. Due to this key rollover, the October message was not signed by persmule. +    b. Obtain the dummy public key from any traditional OpenPGP Keyserver, 
-This did/does not indicate a security incident, all of the statements above +    such as https://keyserver.ubuntu.com, and import the public key. The 
-were valid, and are still valid.+    fingerprint is 0x7636112A33805777A0646B1BFA7C50B699AC61D2. Note that, to 
 +    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.
  
-4. Recent attacks on OpenPGP keyservers have raised great security concerns +    c. This is a special dummy public key with its User-IDs and subkeys stripped 
-within the community, as a countermeasure, persmule's personal User-ID has +    that we specifically created, leaving only a "stub" User-ID (with an invalid 
-not published to the https://keys.openpgp.org/ keyserver. Instead, only +    E-mail address, "Kikek <othar7ok@ep2quey.invalid>"). Its sole purpose is 
-cryptographic information can be obtained from the keyserver, without any +    allowing the subsequent import of additional subkeys.
-User-ID. Currently, it'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.+
  
-5. We are looking for a solution. But for now, we decided that the best +    d. Next, with the stub key already imported, obtain the public key from 
-option is starting publishing new canary documents using the new key. +    https://keys.openpgp.org using the same fingerprint, and import this key. 
-As a temporary measure, you can check the canary documents signed by +    Because the dummy key with its stub User-ID is already in presence, it's 
-biergaizi and wnereiz to decide the validity of the Statements. By signing +    now possible to import the https://keys.openpgp.org public key directly.
-their own copies, it indicates that the new key has been verified privately +
-by them as valid.+
  
-6. This effectively reduced the number of signers to two people. It reduces +    e. Use the latest GnuPG in most operating system, the signatures made by 
-the level of confidence, but currently there is no alternative option yet.+    persmule's key can now be verified as usual.
  
-7. Once the technical problem of OpenPGP public key without User-ID is +3. To verify vimacs' signature...
-resolved, you can check the previous signatures retroactively, and this +
-would effectively restore the level of confidence. You can archive +
-persmule's signature as soon as it's published to your own machine to +
-ensure no data tampering has occured.+
  
-8. Unlike persmule, biergaizi and wnereiz's signing keys are unchanged, +    a. Obtain the public key from any traditional OpenPGP Keyserver, such as 
-but the Key-IDs have been changed to its full fingerprint format in the +    https://keyserver.ubuntu.com, and import the public key. The fingerprint 
-canary document for clarity.+    is 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403.
  
-9. When new information is available, it will be published in the "Special +    b. Use the latest GnuPG in any operating system.
-Announcements" section in future warrant canary documents.+
