Except that in order to write to a pipe the result has to be decrypted first.
I saw this request earlier and could not think of a way around the requirement of reading the entire file and decrypting the data.
It seems to me like you may not see what is really going on. rbatte's example is very good but it does open and read the file.
You could also decrypt the file to /tmp (tmpfs file system) which in solaris is actually memory manged by the kernel. Not disk. Very fast. Pipes can be implemented as shared memory objects as well. If you do that, delete all the files in /tmp as you go.
