I am trying to decrypt a video file using openssl. But 16 byte aes key has a line feed (LF) character in it.

x
yÏï:YÛI?þbl

Because of the LF, when I copy the key to the terminal, it sends only "x" not the whole key.

How can I type this key on terminal?

openssl aes-128-cbc -d -in input.ts -out output.ts -pass [aes_key]

    You, uh, probably don't want to be typing that at all... anyway, try putting it a file and then ``-pass `cat (file)` ``. Or maybe it expects the file, judging from the description, "pass phrase source": `-pass (file)`. And that doesn't look like a passphrase, so maybe you were looking for the `-K` option instead? – Ry- Nov 20 '12 at 15:41

Try parameter -K

from openssl help:

-K/-iv         key/iv in hex is the next argument

So something like this should work 

openssl aes-128-cbc -d -in input.ts -out output.ts -K 00EF45....

where 00EF45.... will be your aes key in hexadecimal format.
