Shell differences for openssl command output
The following works in bash (/bin/bash):

Code:
echo "U2FsdGVkX198UexvhHEtfC7iLbT3awAfla77fvSjZQJ0LC4GmDMeLOghPWXpyy6e" | openssl aes-128-cbc -a -d -salt -pass file:<( echo -n "toy" )

But fails when run in sh (/bin/sh):
Code:
echo "U2FsdGVkX198UexvhHEtfC7iLbT3awAfla77fvSjZQJ0LC4GmDMeLOghPWXpyy6e" | openssl aes-128-cbc -a -d -salt -pass file:<( echo -n "toy" )
sh: 15: Syntax error: "(" unexpected

is there a way around this?

As you can see here, i'm using a named pipe for the password and id like to continue doing that. I just need this (or a very close variation of it) to work in /bin/sh.

That is a bashism called "process substitution". Which sh doesn't offer. Provide a real file with "toy" in it.
