Piotr F. Mieszkowski 5ffbbec5f0 Rename sort_recipients to deliver_message, remove unused imports 2022-06-11 21:05:27 +02:00
Piotr F. Mieszkowski b627fde510 Move gpg-mailgate.py logic to lacre.mailgate module 
gpg-mailgate.py script keeps its role, but only needs to call code defined in
lacre.mailgate.

Piotr F. Mieszkowski 881a8d1756 Add GnuPG encryption support for addresses with delimiters 
If a user registers their key for address alice@example.com but receives a
message sent to alice+something@example.com, this message should be encrypted
as well.

- Implement delimiter support for GnuPG encryption.

- Add E2E test case for a clear text message delivered to an address with
delimiter.

- Fix minor bug: wrong configuration parameter was retrieved when logging
information about enc_domain_keymap being active.

Piotr F. Mieszkowski c86c620668 Extract delimiter support, add unit tests 
Also: fix recursive call to get_cert_for_email.

Piotr F. Mieszkowski 251e6d1270 Record execution time and log it 
After each execution, log an entry with information about total seconds from
the start to the end of execution and the value returned by
time.process_time() function, which returns:

	sum of the kernel and user-space CPU time

according to the documentation.

This feature can be used to collect stats about Lacre performance.

Piotr F. Mieszkowski 937046eb17 Use CRLF for line-endings 
Mail RFCs use CRLF for line endings and it turns out things may break in
strange ways if only LF is used.

Piotr F. Mieszkowski 4c6fdc52ec Check mandatory config early, add tests 
Also: extend failover logging configuration with file-based handler to make
sure that the user gets _some_ logs even if they do not configure Lacre at
all.
 2022-05-31 22:09:10 +02:00
Piotr F. Mieszkowski 3bcc1151e5 Add E2E case: a user with a key and PGP/MIME configured 
- Add a new test input message for a new test identity, test scenario
  configuration and a test key.

- While retrieving message payload, determine charset based on the
  Content-Type header.  When missing, default to UTF-8.

- Use more comprehensible variables names.

- Adjust logging levels.
 2022-05-30 00:49:40 +02:00
Piotr F. Mieszkowski 11b78ce0fb Adjust log entry levels for severe conditions 
When Lacre is misconfigured or can't proceed, report WARNING or even ERROR
level messages.
 2022-05-13 21:27:50 +02:00
Piotr F. Mieszkowski 75ccfb0850 Use logging module 
- Replace custom logging code with calls to logging module.
- Use logging.config to provide configuration parameters.

To make Lacre's logging more flexible, use fileConfig from logging.config to
set up all parameters.  If the configuration file is missing, use dictConfig
with hardcoded reasonable defaults.

Piotr F. Mieszkowski d90b50f7e7 Extract config, separate logging, split into smaller functions 
- Move configuration-processing code to a separate module (lacre.config) and
  provide a simple API to access configuration parameters.
- Prepare to use builtin logging module to log diagnostic data.
- Rework the configuration-processing file to make it cleaner.
- Log additional information while processing configuration.
- Reorder functions.

Piotr F. Mieszkowski 5f02223ec7 Perform automatic migration to Python 3.x 
Use lib2to3 automatic migration tool provided by Python 2.x to convert
codebase to new idioms.

Command line:

    -exec python2.7 -m lib2to3 \
    -f all -f idioms -f buffer -f set_literal -f ws_comma -w \

fkrone 24cfe01d95 Fixing stupid bug with non existing variable. Copy & paste fail. Finding a default key for recipient in domain keymap crashed mailgate. 2015-06-04 19:04:27 +02:00
fkrone 0de0d6a1b1 Critical bugfix: Under some circumstances a mail which should be encrypted with PGP/MIME was not encrypted if at least one attachment ot the body itself contained the PGP-tags. 2015-06-04 16:45:22 +02:00
fkrone 4b7a187ac3 Forgot to change this value from a debug one to the real value 2015-05-29 23:15:05 +02:00
fkrone 11f70fb241 Added possibility to define a regex for finding recipients to decrypt for and also adding possibility to use default keys for domain ranges 2015-05-29 23:13:05 +02:00
fkrone 5fdbabc3b3 Disable PGP/INLINE decryption by default. It does work, however, it has some drawbacks (e.g. content type for files getting lost). 2015-05-25 22:49:42 +02:00
fkrone 2c0e342e5e Support for decrypting PGP encrypted mails. However, it has some drawbacks and might cause some security issues. So before using it please read carefully through the installation instructions. 2015-05-25 20:24:37 +02:00
fkrone 6a7dda969b Bugfix: The mailgate crashes with certain settings when mail is delivered locally 2015-05-25 00:28:55 +02:00
fkrone 4283c7ef4d Prefere keys in keymap over keys in keyring. Could be useful if you have a recipient with two keys. 2015-03-29 18:16:58 +02:00
fkrone dbb65bbf7f Bugfix: Missed return code for failed PGP encryption in log message 2015-03-16 14:58:01 +01:00
fkrone 600b57e6ef Bugfix: Handle multipart messages and especially nested multipart messages correct and not mess up them 2015-03-14 21:52:33 +01:00
fkrone 46730ba8e6 Bugfix: Avoid nested encryptions of any kind 2015-03-02 21:01:05 +01:00
fkrone a766a9bd4a Refactored code (and also optimizing code). 
Changes while refactoring: The gateway now handles mail addresses case sensitivity compitable to RFC 2821 as default.
 2015-03-02 13:13:30 +01:00
fkrone 7934dc00db Little bugfix for PGP/INLINE: Make it working again by stop calling non existing method 
Bugfix for PGP/MIME: Make it compatible to RFC 3156 (MIME Security with OpenPGP) when using mails with attachments
 2015-02-22 14:19:11 +01:00
fkrone c022a2fe9d Added option to overwrite default PGP style (inline or PGP/MIME) for defined recipients (useful if you have some recipients which can't handle one style). 2015-02-19 16:40:48 +01:00
fkrone 92d66a35a5 Bugfix: S/MIME worked only for one recipient because Python handles assignments of lists as call by object references. So the for-loop broke after first iteration. 2015-02-15 15:39:58 +01:00
fkrone ccbe8de7e5 Making S/MIME also compatible with RFC 2821 changes. So both RFC 2821 compatibility and ignoring the case sensitivity of mail addresses are supported my S/MIME. 2015-02-15 15:36:18 +01:00
fkrone 228d43e936 Making GPG-Mailgate compatible with RFC 2821 (Simple Mail Transfer Protocol). The previous reverted commits made the gateway incompatible with the RFC. However, compatibility has to be activated in the settings. Most mail servers ignore the case sensitivity of the mail addresses, so this should not be a big issue. 
A quick solution to make the S/MIME functionality compatible with the RFC was not found so this needs to be fixed later.

fkrone 2ff0b7e123 Revert 0b503fa: Fixing critical bug: looking up email addresses for PGP encryption in keychain was done case sensitive 2015-02-14 19:00:25 +01:00
fkrone c059cfe63b Merged change: 
62f60f0592
( Added option to convert text/plain source email into MIME/PGP attachment style during encryption.

Useful if sending to recipient that can't handle the PGP-inline style. )
 2015-02-14 17:07:02 +01:00
fkrone e2ef883ec2 Merged change: 
584eee18dc
( Added check that config file keymap fingerprint exists in actual GPG keyring. Decline encryption if mismatch. )
 2015-02-14 16:01:58 +01:00
fkrone 63435c72c5 Merged change: 
779e712a5d
( Changed GPGEncryptor.encrypt() to also give PGP return code. Write rc to logfile in encrypt_payload(). )
