libuecc - Very small Elliptic Curve Cryptography library

Age	Commit message (Collapse)	Author
2015-10-17	Add support for the Ed25519 curve	Matthias Schiffer

2015-10-17	Add _legacy suffix to functions accessing points in compressed/coordinate ↵	Matthias Schiffer
	representation
2015-10-17	Add Ed25519-compatible generator point	Matthias Schiffer
	The old point is renamed, as it isn't the only default point anymore. The old name and functions using the old point are deprecated now.
2015-10-17	Fix loading of packed points in edge case	Matthias Schiffer
	The parity bit was not handled correctly when the squeezed value of Y is not fully reduced.
2015-10-09	Fix another comment typo	Matthias Schiffer

2015-10-06	Use stdint types where reasonable	Matthias Schiffer
	Using uint32_t instead of unsigned int for the unpacked work struct ensures the code is working correctly on ABIs with ints narrower than 32 bits. While this would constitute a API/ABI change on some systems in theory, most likely all systems using libuecc so far have uint8_t == unsigned char and uint32_t == unsigned int. Also, coding style cleanup.
2015-10-03	Remove some unnecessary squeeze() calls	Matthias Schiffer
	As only the subtrahend in a sub() call needs to be squeezed, the squeeze can be skipped in these cases.
2015-10-03	Improve documenation of internal functions	Matthias Schiffer

2015-10-03	Fix typo in comment	Matthias Schiffer

2015-10-03	Add comments clarifying when subtractions without squeeze are valid	Matthias Schiffer

2015-10-02	Add functions for point negation and subtraction	Matthias Schiffer

2015-10-02	Move documentation comments for public API to the public header	Matthias Schiffer
	This makes the documentation more accessible, as the header now contains all information regarding the usage of the API, and it is not necessary to generate the Doxygen documentation anymore for that.
2015-01-26	Make default base and identity points accessible	Matthias Schiffer

2015-01-26	Update copyright years	Matthias Schiffer

2015-01-22	Add reduced-bitlength scalar multiplication	Matthias Schiffer

2013-01-09	Check points for validity on load	Matthias Schiffer

2012-12-23	Lots of code documentation	Matthias Schiffer

2012-12-22	Change type names to follow the _t convention, add `deprecated' attribute	Matthias Schiffer

2012-12-08	Add some Doxygen documentation	Matthias Schiffer

2012-12-07	Reworked the API	Matthias Schiffer

2012-03-17	Switch from inverted to extended coordinate representation	Matthias Schiffer
	In inverted coordinates there are 4 points that aren't representable correctly. Avoid this problem by using the extended coordinate representation, in which an add+double operation has essentially the same performance as in the inverted representation.
2012-03-16	For Edwards curves, the identity element isn't at infinity, so rename the ↵	Matthias Schiffer
	identity check function accordingly
2012-03-14	Some more renamed, some utility functions	Matthias Schiffer

2012-03-14	Code cleanup	Matthias Schiffer

2012-03-14	Fixed square_root()	Matthias Schiffer

2012-03-14	Formatting improvements	Matthias Schiffer

2012-03-14	More renames, added secret key arithmetic	Matthias Schiffer

2012-03-13	Some renames, fix load function, add default base	Matthias Schiffer

2012-03-13	Correctly rename all functions to match header file	Matthias Schiffer

2012-03-13	Initial version	Matthias Schiffer
