Redirect output of program into a variable in shell script

Question

Can somebody help on this

I want to redirect the output from openssl to a variable in shell script. Like this

openssl rsautl -decrypt -inkey inp -in inenc -out [to some variable]

As of now I'm trying to achieve like this

var=$(openssl rsautl -decrypt -inkey inp -in inenc -out >(xargs))

But instead of that I need some one liner code to do this without using xargs

Because openssl emits to stdout by default, you can omit the whole -out part:

var=$(openssl rsautl -decrypt -inkey inp -in inenc)

should work just fine.
