Reverse Annnnnnny-Second-Now The function super_optimized_calculation is a Fibonacci generator. To solve this chall, we just use the 90th Fibonacci number and modulo it by each number in the v6 array. Code: v6=[0]*25 v6[0] = 35831; v6[1] = 143; v6[2] = 1061; v6[3] = 877; v6[4] = 29463179; v6[5] = 229; v6[6] = 112; v6[7] = 337; v6[8] = 1061; v6[9] = 47; v6[10] = 29599; v6[11] = 145; v6[12] = 127; v6[13] = 271639; v6[14] = 127; v6[15] = 353; v6[16] = 193; v6[17] = 191; v6[18] = 337; v6[19] = 1061; v6[20] = 193; v6[21] = 353; v6[22] = 269; v6[23] = 487; v6[24] = 245; a = 2880067194370816120 & ((1<<64)-1) for i in v6: print(chr(a%i),end='') js-safe After deobfuscating the code, we can see that the function addToPassword use some operation to check the pass code....
