Secret key definition

Secret key	PRNG–EHSHM
60 Hex characters	$H_1,H_2,\dots ,H_{60}$ where $H\in [0-9,A-F]$
Values	$A=\frac{{(H_1,H_2,\dots ,H_6)}_{10}}{2^{23}+1}$	$B=\frac{{(H_7,H_8,\dots ,H_{12})}_{10}}{2^{23}+1}$	$C=\frac{{(H_{13},H_{14},\dots ,H_{18})}_{10}}{2^{23}+1}$
	$D=\frac{{(H_{19},H_{20},\dots ,H_{24})}_{10}}{2^{23}+1}$	$E=\frac{{(H_{25},H_{26},\dots ,H_{30})}_{10}}{2^{23}+1}$	$F=\frac{{(H_{31},H_{32},\dots ,H_{36})}_{10}}{2^{23}+1}$
	$G=\frac{{(H_{37},H_{38},\dots ,H_{42})}_{10}}{2^{23}+1}$	$H=\frac{{(H_{43},H_{44},\dots ,H_{48})}_{10}}{2^{23}+1}$	$I=\frac{{(H_{49},H_{50},\dots ,H_{54})}_{10}}{2^{23}+1}$
	$J=\frac{{(H_{55},H_{56},\dots ,H_{60})}_{10}}{2^{23}+1}$
Control parameters	$\alpha =rem(A+B,1)$	$\beta =rem(C+D,1)$	$\gamma =rem(E+F,1)$
Initial conditions	$x=rem(G+H,1)$	$y=rem(I+J,1)$
