Password Algorithm 512×512

Password Algorithm 512×512 (PAP-512 v2 ),a fundamentally new architecture base on dual asymetric pyramids operating in opposite directions ( tip-base and base-tip) with K2 activation in every round. PAP-512 v2 resist differential attack, related- key attacks, length extension attacks, and fixed-point attacks. With a preimage space of 2^ 4096 ( post- quantum 2^ 2048 ), it offers inherent quantum resistance. The algorithm achieves optimal performance for mobile and embedded systems (363 H/s ), making it an ideal choice for applications where speed and security must coexist.
