Purpose is to wait before asking passphrase.
For example, if you were to decrypt something already encrypted, and then
re-encrypt it again with different key file or passphrase, you can use two
aespipe processes like this:
... | aespipe -d | aespipe | ...
In above case, both aespipe processes end up asking for passphrase
simultaneously. But how do you know which aespipe process gets first
passphrase? You don't. This works more consistently:
... | aespipe -d | aespipe -w 60 | ...
^^^^^
aespipe README example 3 attempts to prevent aespipe password prompt from
getting lost in mkisofs output noise by using -w option like this:
mkisofs -r directory-tree | aespipe -w 10 -K image.iso -O 16 >>image.iso
^^^^^
But that doesn't always work. It is better to just tell mkisofs to just shut
up. Like this:
mkisofs -quiet -r directory-tree | aespipe -K image.iso -O 16 >>image.iso
^^^^^^
