title: AES encryption with plain text key using bash openssl
body: <p>I am trying to encrypt a string using AES CBC. The output of the online tool (<a href="http://aes.online-domain-tools.com/" rel="nofollow">http://aes.online-domain-tools.com/</a>) and the bash openssl command do not match. Can anyone help me with what I am doing wrong? </p>
  
  <p><code>key = 12345678912345678912345678912345
  iv="e90e89a2277f4f3b6a2080d27f734266" #using the one generated by online tool
  openssl enc -aes-256-cbc -in input.txt -out output.txt -K $key -iv $iv</code></p>
  
  <p>EDIT - more info on the settings chosen on the site - </p>
  
  <p><code>Input type - plain text
  Function - AES
  Mode - CBC
  Key - (plain) - 12345678912345678912345678912345
  Init Vector - e9 0e 89 a2 27 7f 4f 3b 6a 20 80 d2 7f 73 42 66</code></p>
