Encrypting files with a decryption key

I'm writing a program that needs to encrypt a log file using openssl and have a decryption key. For example I want to encrypt this file:

This is a test of encrypting a file

This is a test of encrypting a file

Using openssl and I want to be able to decrypt it when I put in some decryption key, for sake of argument 123456789 will be the key.

def decrypt
  print 'Enter key: '
  key = gets.chomp
  if key == decryption_key
    # decrypt file
  else
    # don't decrypt file
  end
end

I've read the docs on openssl but I still don't fully understand how it works, could someone give me an example of what I'm trying to do, along with an example of the decryption part please?

Using aes gem you can do something like:

key = AES.key    
b64 = AES.encrypt("A super secret message", key)
AES.decrypt(b64, key) # => "A super secret message"
