title: Secure(ish) encryption/decryption algorithms in vb.net using a string as a key
body: <p>Is there a way to encrypt/decrypt text (string form) in VB.net using another string as a key? Meaning, if one user encrypts using this key, the other user needs to decrypt using the same key?</p>
  
  <p>I do NOT mean public and private key encryption or anything of the sort.</p>
  
  <p>Can someone help me build two subs for these?</p>
  
  <p>If not, what is the second best way to encrypt/decrypt data without public/private keys?</p>
  
  <p>I want to make a simple way to send messages securely.</p>
  
  <p>Thanks for the help!</p>
