c# - SQL Server Format-Preserving encryption -


i have old system database has table column of type char(20) , customer decided encrypt column business needs system integration needs length of output column similar input 20 , have read format-preserving encryption

my question is, format-preserving encryption strong aes methods , there sql server implementations yet can used large number of records millions?

you can build secure format-preserving encryption based on aes. here answer different question, show code implements format-preserving encryption using aes building block. see this lecture on format-preserving encryption professor boneh of stanford university details on how can done.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
