Release Notes: This is a code cleanup and bugfix release. First, some namespace issues have been solved in order to compile with newer versions of GCC and stdc++. Additionally, a bug in the rank statistic command has been fixed. This bug was introduced in the previous version 2.8. Finally, the obsolete GnuTLS dependency has been removed.
Release Notes: The cryptographic key generation has been improved and some obsolete functions removed.
Release Notes: The focus of this release are major feature enhancements in LibTMCG, which improve the performance and communication complexity of SecureSkat significantly. Unfortunately, because of this change it is not possible to establish game sessions with versions prior to 2.7. Further, key fingerprints are now shown by the command /players, and null games are aborted immediately if they are lost by the playing party.
Release Notes: This release uses a more secure key derivation function (PBKDF1) from RFC 2898. For compatibility reasons, the former encrypted keys are still readable. Furthermore, there exist user commands to export and import a public key manually. The key and ranking databases are now stored in the directory ~/.SecureSkat. A new cryptographic group (from RFC 2412) is included. Unfortunately, because of this change it is not possible to establish game sessions with older versions of SecureSkat.
Release Notes: This is mainly a bugfix release. However, some rudimentary internationalization support (German translation only) has been added. Further, the secret key is now protected by encryption with a user-supplied pass phrase.
Release Notes: The main focus of release is the separation of libTMCG from this package. A pre-release snapshot of the library is available at Savannah.
Release Notes: This release fixes two security issues. It no longer uses shortened exponents, because there are additional cryptographic assumptions (DLSE) to make them secure. It also fixes a problem with the implementation of a proof of knowledge (which shows the equality of discrete logarithms), where the missing instantiation of the hash function on the verifier side permitted cheating.
Release Notes: The shared library libTMCG is included. It can be used to create secure card games or similar projects, like secure multi-party computation.
Release Notes: This release fixes a major security flaw that lead to cryptographically weak card encodings. A common group is used for the included secret voting scheme.
Release Notes: This release fixes some memory leaks and insufficient allocations. Some minor changes have been applied during portage to Darwin/PowerPC. A security-related typo was fixed in the function CheckGroup() of the VTMF implementation. For performance reasons, openSkat uses a common group (DDH-hard) for card encoding by default.
