Help with openssl and rc4

I'm trying to use the command line openssl enc program to decrypt some text. The encryption is happening on another computer but I'm not sure what options it's using. If I got to this site (http://rc4.online-domain-tools.com/), I am able to decrypt fine. But I can't seem to get it to work with openssl.

An example would be if you have a hex string of daea5465, you can use the key "test" to decrypt it to "test" on that site. But if I use an input file with that hex string and the hex string of "74657374" ("test" in hex), I get garbage back out. This was the command string I was using: openssl enc -d -rc4 -in test.hex -out output.txt -K 74657374 -nosalt. Which comes out to "+]VO��i". Anyone have any ideas? I assume I'm missing some switch or something but I've tried everything I could find on it.
