~~~~~~~~~~~~~~~~~~~~~~~~ | ~~~~~~~~~~~~~~~~~~~~~~~~ | ||
- | 1. Since mid-October, | + | 1. We've found a workaround for importing keys on https:// |
- | expired. A new key, 0xEDFFE248ECFACDE3C805906804A40D21DBB89B60, | + | without User-ID. The instructions for verifying |

+ | Canary Verification Procedures | ||
+ | ~~~~~~~~~~~~~~~~~~~~~~~~ | ||
+ | |||
+ | 1. To verify biergaizi' | ||
+ | |||
+ | a. Obtain the public | ||
+ | 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' | ||
- | 2. The new key will be used by persmule | + | a. Due to the previous attacks on OpenPGP keyservers, persmule has published |
- | documents. You can verify | + | the OpenPGP public key to https:// |
- | documents signed by biergaizi and wnereiz for consistency. | + | |
+ | 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 | + | such as https:// |
- | were valid, and are still valid. | + | fingerprint is 0xEDFFE248ECFACDE3C805906804A40D21DBB89B60. Note that, to |
+ | import | ||
+ | | ||
+ | | ||
+ | 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, | + | that we specifically created, leaving |
- | not published to the https:// | + | E-mail address, " |
- | cryptographic information can be obtained from the keyserver, without any | + | |
- | 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 | + | |
- | 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 | + | |
- | As a temporary measure, you can check the canary documents signed by | + | |
- | biergaizi and wnereiz | + | now possible |
- | their own copies, it indicates that the new key has been verified privately | + | |
- | by them as valid. | + | |
- | 6. This effectively reduced | + | 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' |
+ | 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 " | ||
+ | error. | ||
- | 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, | + | |
- | would effectively restore the level of confidence. You can archive | + | |
- | persmule's signature | + | |
- | ensure no data tampering has occured. | + | |
- | 8. Unlike persmule, biergaizi and wnereiz' | + | a. Obtain the public key from any traditional OpenPGP Keyserver, such as |
- | but the Key-IDs have been changed to its full fingerprint | + | |
- | canary document for clarity. | + | is 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403. |
