Is "P = H(rA)G + B" still used in creating stealth addresses?
I know this is the original iteration of DHKE in CryptoNote but previous posts seem to mention other functions such as "**X = Hs(r\*PV| i )G + PS" and** **c = H(r·s·G) = H(r·S) = H(s·R).** Am I missing something or is "P = H(rA)G + B" still the primary equation used? Are these other iterations or improved DHKE variants? I'm writing a research paper that partially discusses Monero so still wrapping my head around things. All help appreciated!
