openssl unknown option error - linux

Question

I ran this script below:
#!/bin/bash
keyFile=video.key
openssl rand 16 > $keyFile
encryptionKey=$(cat $keyFile | hexdump -e '16/1 "%02x"')
splitFilePrefix=stream
encryptedSplitFilePrefix=enc/${splitFilePrefix}
numberOfTsFiles=$(ls ${splitFilePrefix}*.ts | wc -l)
for (( i=1; i<$numberOfTsFiles; i++ ))
do
initializationVector=printf '%032x' $i
openssl aes-128-cbc -e -in ${splitFilePrefix}$i.ts -out ${encryptedSplitFilePrefix}$i.ts -nosalt -iv $initializationVector -K $encryptionKey
done
right after the execution, the bash gives me an error:
./script.sh: line 14: fg: no job control
unknown option '9d268d620c68938b4578c3f299c91a1a'
options are
-in <file> input file
-out <file> output file
-pass <arg> pass phrase source
-e encrypt
-d decrypt
-a/-base64 base64 encode/decode, depending on encryption flag
-k passphrase is the next argument
-kfile passphrase is the first line of the file argument
-md the next argument is the md to use to create a key
from a passphrase. One of md2, md5, sha or sha1
-S salt in hex is the next argument
-K/-iv key/iv in hex is the next argument
-[pP] print the iv/key (then exit if -P)
-bufsize <n> buffer size
-nopad disable standard block padding
-engine e use engine e, possibly a hardware device.

I read openssl manual and thought either -K or -iv part is wrong, but couldn't figure out which option and why is it wrong

Answer 1

Your problem is that this line:
initializationVector=printf '%032x' $i
Should look like this:
initializationVector=$(printf '%032x' $i)
It made initializationVector empty.
You can find it out if you add set -x at the top, and then see exactly what is the command line you're attempting to run.
before fixing it looked like this:
openssl aes-128-cbc -e -in stream1.ts -out enc/stream1.ts -nosalt -iv -K 7aeb2faae0289b9828b2994f50a4cc3a
which made openssl command think that -K is the value for the -iv option, and the key itself is another command option.
Hence the error: unknown option '7aeb2faae0289b9828b2994f50a4cc3a' (in my case).

Answer 2

do
initializationVector=printf '%032x' $i
openssl aes-128-cbc -e -in ${splitFilePrefix}$i.ts -out ${encryptedSplitFilePrefix}$i.ts \
-nosalt -iv $initializationVector -K $encryptionKey
done
You are missing the leading dash on the cipher. Try -aes-128-cbc instead. From the enc(1) docs:
SYNOPSIS
openssl enc -ciphername [-in filename] [-out filename] [-pass arg] [-e] [-d] [-a/-base64] [-A]
[-k password] [-kfile filename] [-K key] [-iv IV] [-S salt] [-salt] [-nosalt] [-z] [-md] [-p]
[-P] [-bufsize number] [-nopad] [-debug] [-none] [-engine id]
