This release is two-fold: first, it fixes some bugs (e.g. iterated S2K) of the OpenPGP interface, and second, it adds functionality for handling v5 keys and signatures (see RFC 4880bis-07).

This is a maintenance release that fixes a major bug in the VSSHE module (Groth's shuffle protocol). The verification of the special component E_d with respect to membership in the underlying commitment group has been done wrongly by a fast exponentiation function with fixed bases. Hence the check of membership for this component is always [...]

In this release AEAD support has been added to the OpenPGP interface. Please note that this feature is specified by working draft only and was not part of the aged RFC 4880. Moreover, some bugs have been fixed and some library constants (e.g. TMCG_MAX_CARDS) have been adjusted.

This is a maintenance release that fixes some bugs, e.g. in the Botan support of functions from module mpz_srandom. Moreover, some interfaces of the OpenPGP implemenation have been added and removed. For some modules of LibTMCG a basic C++ exception handling has been introduced.

With this release three additional parameters for the control of secure memory allocation have been added to function init_libTMCG(). They are explained in the reference manual. Moreover, the OpenPGP interface has been enhanced in several way, e.g., ECDH, ECDSA and EdDSA are supported now.

This release contains again a lot of major improvements for the still undocumented OpenPGP interface, e.g. C++ classes for basic structures like public keys, messages or signatures. The PRNG from Botan is used for as an additional source of randomness, if LibTMCG is configured and built [...]

Major improvements for OpenPGP interfaces have been achieved. Notable are the new classes for processing public key structures. Moreover, a second indepent hash algorithm (SHA3) has been included for computing the oracle hash function g(). This adds the requirement of libgcrypt >= 1.7.0 for dependencies and breaks compatibility of NIZK or [...]

Some small enhancements for the OpenPGP interfaces and the library initialization have been implemented. Unfortunately, the changes may require also an update of the application to be effective.
