Purpose of patch
0000911: Wrong expiration time in newly added GPG Key if Key has no Expire date
Patch Testing Requirements
assured member, at least 50 pts
test gpg keys w/ & w/o expiry date set
Bug 911 - Instructions/Infos
Instructions and Sample Test Matrix for Software Testers
In the error case users received expired GPG keys in the view GPG keys list with date set "1971-01-02" in expires field with realy fresh new created GPG keys, expiry date set or not at built time.
CAcert's points system for Assuree's and Assurers is as follows:
Assurance points, Certs that expires after 1/2 year
Assurance points, Certs expires after 2 years addtl. GPG/PGP keys can be added
Fully Assured (same as 50-99)
CATS will be added and activated if CATS passed
Possibility to request Codesigning (adding Codesigning flag onto the account possible)
Possibility to assure others
(100+) 0-50 pts
Experience points for each assurance you'll receive 2 experience points
The GPG key and the Expiry date shown in GPG view keys list
A note towards the expire date as shown by CAcert: There is a bug which has hopefully been fixed on the test system but from what I gather from the comments above there is also a misunderstanding:
The expiry date shown is not that of the key itself but of the Signature of CAcert.
That means your key will still be valid in general but the signature that CAcert did on your key will expire so you just have to resign it to get a valid signature again.
Unfortunately most GUI tools don't show the expiration of a signature.
On the command line you can check out the validity of the signatures on a key by running
"gpg --check-sigs <key-ID>". The "X" indicates an eXpired signature.
For this test you'll need:
- one account with at least 50 assurance points.
- GnuPG installed on your local machine (to create gpg keys)
Instructions to create pgp test keys
gpg --gen-key Please select what kind of key you want: (1) DSA and Elgamal (default) (2) DSA (sign only) (5) RSA (sign only) Your selection? -> 1 DSA keypair will have 1024 bits. ELG-E keys may be between 1024 and 4096 bits long. What keysize do you want? (2048) -> 4096 Requested keysize is 4096 bits Please specify how long the key should be valid. 0 = key does not expire <n> = key expires in n days <n>w = key expires in n weeks <n>m = key expires in n months <n>y = key expires in n years Key is valid for? (0) -> Enter Key does not expire at all Is this correct? (y/N) -> y You need a user ID to identify your key; the software constructs the user ID from the Real Name, Comment and Email Address in this form: "Heinrich Heine (Der Dichter) <firstname.lastname@example.org>" Real name: -> My Givenname Surname Email address: -> email@example.com Comment: You selected this USER-ID: "My Givenname Surname <firstname.lastname@example.org>" Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? -> o You need a Passphrase to protect your secret key. Enter passphrase: -> enter a passphrase Repeat passphrase: -> enter your passphrase We need to generate a lot of random bytes. It is a good idea to perform some other action (type on the keyboard, move the mouse, utilize the disks) during the prime generation; this gives the random number generator a better chance to gain enough entropy. +++++++++++++++...++++++++++.+++++++++++++++++++++++++.+++++++++++++++++++++++++ +++++..+++++.++++++++++..++++++++++.+++++++++++++++...++++++++++>++++++++++.<.++ +++...>++++++++++ We need to generate a lot of random bytes.
