- Change initial message box to mention delay when downloading/parsing.
Since there is no progress meter it was somewhat unexpected that after
choosing a filename nothing appears to happen, when actually the cert
data is in the process of being downloaded and parsed.
- Warn if OpenSSL is not present.
- Use a UTF-8 stream to make the ca-bundle data.
- Save the UTF-8 ca-bundle stream as binary so that no BOM is added.
---
This is a follow-up to d2c6d15 which switched mk-ca-bundle.vbs output to
ANSI due to corrupt UTF-8 output, now fixed.
This change completes making the default certificate bundle output of
mk-ca-bundle.vbs as close as possible to that of mk-ca-bundle.pl, which
should make it easier to review any difference between their output.

Bring the VBScript version more in line with the perl version:
- Change timestamp to UTC.
- Change URL retrieval to HTTPS-only by default.
- Comment out the options that disabled SSL cert checking by default.
- Assume OpenSSL is present, get SHA256. And add a flag to toggle it.
- Fix cert issuer name output.
The cert issuer output is now ansi, converted from UTF-8. Prior to this
it was corrupt UTF-8. It turns out though we can work with UTF-8 the
FSO object that writes ca-bundle can't write UTF-8, so there will have
to be some alternative if UTF-8 is needed (like an ADODB.Stream).
- Disable the certificate text info feature.
The certificate text info doesn't work properly with any recent OpenSSL.

- Change all predefined Mozilla URLs to HTTPS (Gregory Szorc).
- New option -k to allow URLs other than HTTPS and enable HTTP fallback.
Prior to this change the default URL retrieval mode was to fall back to
HTTP if HTTPS didn't work.

This hash is used to verify the original downloaded certificate bundle
and also included in the generated bundle's comment header. Also
rename related internal symbols to algorithm-agnostic names.
|
|
Makes the script pass on comments holding meta data to the output
file. Like fingerprinters, issuer, date ranges etc.
Closes #937

Also unified printing to STDERR by creating the helper method "report".

Prefer usage of Perl modules for sha1 calculation since there
might be systems where openssl is not installed or not in path.
If openssl is used for sha1 calculation then dont rely on cut
since it is usually not available on other systems than Linux.

Certificates based on SHA-1 are being phased out[1].
So we should expect a rise in certificates based on SHA-2.
Adding SHA-384 as a valid signature algorithm.

As a sort of step forward, this script will now first try to get the
data from the HTTPS URL using curl, and only if that fails it will
switch back to the HTTP transfer using perl's native LWP functionality.
To reduce the risk of this script being tricked.
Using HTTPS to get a cert bundle introduces a chicken-and-egg problem so
we can't really ever completely disable HTTP, but chances are that most
users already have a ca cert bundle that trusts the mozilla.org site
that this script downloads from.
A future version of this script will probably switch to require a
dedicated "insecure" command line option to allow downloading over HTTP
(or unverified HTTPS).

... as mxr.mozilla.org is due to be retired.
The new host doesn't support If-Modified-Since nor ETags, meaning that
the script will now defer to download and do a post-transfer checksum
check to see if a new output is to be generated. The new output format
will hold the SHA1 checksum of the source file for that purpose.
We call this version 1.22

-p takes a list of Mozilla trust purposes and levels for certificates to
include in output. Takes the form of a comma separated list of
purposes, a colon, and a comma separated list of levels.

This changes the previous check for untrusted certs to a check for
certs explicitely marked as trusted.
The change is backward-compatible (tested with certdata.txt v1.80).
|
|
Christian Heimes brought to our attention that the certdata.txt
format has recently changed [1], causing ca-bundle.crt created
with mk-ca-bundle.[pl|vbs] to include untrusted certs.

The previously applied patch didnt work on Windows; we cant rely
on shell commands like 'echo' since they act diffently on each
platform and each shell.
In order to keep this script platform-independent the code must
only use pure Perl.

The OpenSSL pipe wrote to the final CA bundle file, but the encoded PEM
output wrote to a temporary file. Consequently, the OpenSSL output was
lost when the temp file was renamed to the final file at script finish
(overwriting the final file written earlier by openssl).

1. When the downloaded data file from Mozilla is current, but the output
bundle does not exist: continue processing to create the bundle. The
goal is to have the output file - not just download the latest input.
2. added -f option to force re-processing the file. Useful for
debugging/testing the process.
3. added support for output to '-' (stdout), allowing the output to be
piped.
4. All progress and error messages go to STDERR rather than STDOUT (3)
5. The script opened and closed the output file many times
unnecessarily. It now opens it once, does the output and closes it.
6. Backup of the input files happens after successful processing, not
before.
7. The output is written to a temporary file, and renamed to the
requested name after backup - this greatly reduces the window where the
file can be seen partially written.
8. all die calls have a \n at the end to suppress perl's traceback - the
traceback isn't useful to end users.

Each certificate section of the input certdata.txt file has a trust
section following it with details.
This script failed to detect the start of the trust for at least one
cert[*], which made the script continue pass that section into the next
one where it found an 'untrusted' marker and as a result that certficate
was not included in the output.
[*] = "Hellenic Academic and Research Institutions RootCA 2011"

This reverts commit f7e2ab6.

This reverts commit 9f0e1689f169b83b8fbdae23e0024cc57dcbc770.
It turned out that "improvement" instead made the fetching of the
certificates unreliable

An alternative would be:
1. specify HTTPS_CA_DIR and/or HTTPS_CA_FILE
2. ensure that Net::SSL is being used, and IO::Socket::SSL is NOT being
used

When I decided to search for a potential error with the cacert bundle it
struck me I wanted to see the full source URL in the output...

Only download and convert the certdata to the ca-bundle.crt if Mozilla
changed the data
The Perl LWP module (which in a bit of a circular reference is used by
mk-ca-bundle.pl) is now indirectly using this script. I made this small
tweak to make it easier to automatically maintain the generated
ca-bundle.crt file in version control.

The official Mozilla page at
http://www.mozilla.org/projects/security/certs/ points out a new place
as the "proper" place to get Mozilla's CA certs from so this script is
now updated to use that instead.
