Changelog for libuecc-7-2.1.x86_64.rpm :

* Wed Aug 16 2017 svenAATTuebelacker.net- update to libuecc v7 (2016/03/27)- Change conversion between Ed25519 and legacy representation. This should not affect any operations unless Ed25519 and legacy load/store functions are mixed when accessing a work structure. Doing so is now officially supported, for example to convert a legacy public key to Ed25519 format.- The changed representation allows to use the same ecc_25519_work_default_base for both Ed25519 and legacy. ecc_25519_work_default_base and ecc_25519_scalarmult_base have been undeprecated, ecc_25519_work_base_ed25519 and ecc_25519_work_base_legacy are deprecated now.- All points are now internally represented with Ed25519 coordinates, which allows about 6% faster scalar multplication than the legacy representation.- ecc_25519_scalarmult_base has been further optimized, making it another 6% faster than normal ecc_25519_scalarmult.
* Fri Oct 30 2015 svenAATTuebelacker.net- update to libuecc v6 (2015/10/25) - Fixes a bug which might have caused a point\'s y coordinate to be negated in certain circumstances when the point was stored in packed representation and loaded again. It is extremely improbable that this has ever actually happened, as only a small range of coordinates was affected. - Use stdint types to clarify ABI and add support for systems with sizeof(int) < 4 (this is not an ABI break in practise as all systems on which libuecc has been used in the past should have int == int32_t) - Add point negation and subtraction functions - Rename all point access functions to bear a _legacy suffix (the old names are still available, but marked as deprecated) - Add new point access functions and a new generator point that are compatible with Ed25519
* Mon Jan 06 2014 svenAATTuebelacker.net- update to version 4
* Fri Dec 28 2012 svenAATTuebelacker.net- initial port to openSUSE of version 0.1
