Lucas Soriano del Pino	83042c4148	OMG Monero transactions!!!!!!!!	2021-05-13 12:35:34 +10:00
Lucas Soriano del Pino	56128bb3a8	Some fixes ... - Use correct key image for both signing and constructing transaction. - Sort ring and commitment ring according to key offset order. - Given the new order of items in the ring, allow asigning index values different to 0. This breaks signature verification, both locally and against Monero!	2021-05-13 11:34:58 +10:00

Thomas Eizinger	58074fc083	ONLY PARTIALLY WORKING: Allow signing algorithm to be given signing key index ... At the moment this works only if the index is 0.	2021-05-12 19:01:30 +10:00
