XCA 1.0.0 Released

I finally got the time to make a new release.
Even though this actually is only a patch release fixing some bugs
I called it Version 1.0.0 since it is pretty complete and stable.

I hope the next release won't take more than 2 years...

Enjoy XCA

OpenSSL Heartbleed (CVE-2014-0160) and XCA

In short

XCA is not affected at all by the Heartbleed vulnerability,
because it does not do any SSL/TLS related things.

Long version

The Windows/MacOSX version of XCA comes with an OpenSSL version (number) which is affected.
On unix-ish hosts XCA uses the OpenSSL library of the host system.

OpenSSL is split in 2 librarys
1. The crypto library: libcrypto.so (libeay32.dll) containing all the X.509 crypto and hash functions
2. The SSL/TLS library: libssl.so (libssl32.dll) containing the HTTPS network code and the Heartbleed bug... read more

XCA 0.7.0 released

There are several fixes in this release. The validation of certificate requests was made working again. During certificate creation xca notifies about duplicate v3 extensions. The default hashing algorithm was reset to SHA1, since too many applications can't handle SHA256 correctly, yet.

New features:
- PEM import feature added to paste or open a file and autodetect the content
- The subject of certificate requests can be modified before signing
- Arbitrary X509v3 extensions may be added by using the OpenSSL config file format on the "Advanced Settings" Tab
- A validation button computes and displays all extensions before creating the certificate... read more

XCA 0.6.3 released

The release of XCA 0.6.3 comes with an options dialog where
the following settings can be adjusted per database:
The default hash-algo can be set to SHA1 for all users with clients
that can not handle the current default of SHA256. Additionally a list of mandatory
distinguished name entries can be set to get warned if one of them is empty
during certificate rollout.
Usually xca takes care that a key is only used once.
Some people asked my to help them shooting themselves into the foot,
so I added an option to use keys more than once.
The internal handling of umlauts was moved to UTF8.
It may be possible that some of your key and certificate internal names
show rubish where non 7bit ASCII characters have been. This is
no issue, since you can easily rename the items in question. This will not change
its content.... read more

beta of xca 0.6.0 released

It needed some time to port XCA to QT4. This enables me to use a modern API and take advantage of the free Windows port of QT4 for free software.

A lot of new features were added, like v3 extensions for requests or the more convenient input dialogs for issuer-alternative-name and others.
The Cetificate-wizard got replace by a tab-dialog to enhance the usability. The switch to OpenSSL 0.9.8 enables the newer hashing algos SHA256 and SHA512. The storage type of the asymmetric keys (DSA is supported now, too) was changed. The private key remains encrypted in the db and is only decrypted on demand. The keys also may get protected by different passwords.... read more

Release of xca 0.4.6

This new version fixes some bugs in handling the commandline options especially is it possible again to select an other database name.
The configure system was reduced to a small configure script removin 1/3 of the needed diskspace of the tar ball.
The dates in the created CRLs were changed to be compatible to netscape.

XCA signing error

XCA does create malformed certificates under some circumstances:

When creating a certificate with XCA and selecting
"Authority Key Identifier" it takes the values from an other
than the signing certificate.
This results to invalid certificates !!

All versions of xca from 0.4.0 to 0.4.2 are affected.
The 0.3 series is not affected.

Impact:
Dumb implemetations like IE do easily ignore it, but
others like CISCO VPN routers or Mozilla do
reject such malformed certificates.... read more
