title: base64 encoded iv? (NSISCrypt) Symmetric Encryption
body: <p>So im trying to use a plugin called NSISCrypt for a NSIS Installer, Im wanting to obfuscate a register password.</p>
  
  <p>So there are some easy Base64 encryption and decryption. So I thought HEY! great....
  <a href="http://nsis.sourceforge.net/NsisCrypt_plug-in" rel="nofollow">http://nsis.sourceforge.net/NsisCrypt_plug-in</a> (He is the Readme for it)</p>
  
  <p>Problem is Im not really sure what the Base64 iv is.....i've googled base64 iv and have come up with nothing.</p>
  
  <p>Im not expert at encryption, however I understand what a Preshared Key is of course.....but what would a BaseIV be?</p>
