You are only overwriting the pointer to the string (a string is essentially a
pointer and a length). If you want to use memory and then zero it out, use a
byte slice instead and be careful to not call append where append might
allocate new memory. Take a look at https://play.golang.org/p/GkrKR
Jay,
A Go string is represented by a struct.
type stringStruct struct {
str unsafe.Pointer
len int
}
Assigning a new value to a string variable is a struct assignment that does
not immediately destroy the underlying value of the original string.

https://github.com/awnumar/memguard is the only project I've noticed that
attempts to deal with string security in Go.
I haven't used it personally.

For security, you should use a []byte and overwrite there, and never create
a string out of it (that'd induce a copy).

The same concept applies as before. String variables are unique
*@Jan*, The example you shown it is copying a string to new variable. but
my question was related to same variable.
I want to know if I have variable :
x := "testsring"
Now it overwrite the content of same variable x to some other value:
x = "new1string"
Will it overwrite the same memory or i
I think Jan answered the question asked. But, do you have some specific
concern that prompted the question? Is it about security, or memory usage,
or just curiosity?
