 +Canary Verification Procedures 
 +~~~~~~~~~~~~~~~~~~~~~~~~ 
 + 
 +1. To verify biergaizi's signature... 
 + 
 +    a. Obtain the public key from any traditional OpenPGP Keyserversuch as 
 +    https://keyserver.ubuntu.comand import the public key. The fingerprint 
 +    is 0x255211B2395A5A3E0E48A0F1FAD3EB05E88E8D6D. 
 + 
 +    b. Use the latest GnuPG in any operating system. 
 + 
 +2. To verify persmule's signature...
  
-2The new key will be used by persmule to sign future warrant canary +    aDue to the previous attacks on OpenPGP keyservers, persmule has published 
-documentsYou 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.
  
-3Due to this key rollover, the October message was not signed by persmule. +    bObtain the dummy public key from any traditional OpenPGP Keyserver, 
-This did/does not indicate security incident, all of the statements above +    such as https://keyserver.ubuntu.com, and import the public key. The 
-were validand are still valid.+    fingerprint is 0xEDFFE248ECFACDE3C805906804A40D21DBB89B60. Note that, to 
 +    import this key, one must copy and paste the key in ASCII from the Keyserver 
 +    website to file or console and use the command "gpg --import". Due to a 
 +    technical problemUsing "gpg --recv-key" or "gpg --search-keys" does not 
 +    work.
  
-4Recent attacks on OpenPGP keyservers have raised great security concerns +    cThis is special dummy public key with its User-IDs and subkeys stripped 
-within the community, as countermeasure, persmule's personal User-ID has +    that we specifically createdleaving only a "stub" User-ID (with an invalid 
-not published to the https://keys.openpgp.org/ keyserver. Instead, only +    E-mail address"glahamm <yiam5Od@gliwrad.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 installationas 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 nowwe decided that the best +    dNextwith 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 StatementsBy 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.+
  
-6This effectively reduced the number of signers to two peopleIt reduces +    eUse 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 usualDebian is known to work, most 
 +    other systems should work just fine, but not Fedora. The subkeys contains 
 +    signatures made with Brainpool curves, which are disabled on Fedora due to 
 +    potential patent-licensing problems, causing a "Unknown elliptic curve" 
 +    error.
  
-7Once the technical problem of OpenPGP public key without User-ID is +3To verify vimacs' signature...
-resolved, you can check the previous signatures retroactively, and this +
-would effectively restore the level of confidence. You can archive +
-persmule'signature as soon as it's published to your own machine to +
-ensure no data tampering has occured.+
  
-8Unlike persmule, biergaizi and wnereiz's signing keys are unchanged+    aObtain the public key from any traditional OpenPGP Keyserversuch 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

-9When new information is available, it will be published in the "Special +    bUse the latest GnuPG in any operating system.
