Encrypt with ROT13

Encrypt any text with the famous ROT13 encryption algorithm online for free. Warning: ROT13 is NOT a safe encryption algorithm and can be decoded by ANYONE.

If you are like me, you may remember that as a child you encrypted messages to your sibling or friend by rotating letters around: "A" becomes "N", "B" becomes "O", "C" becomes "P" and so on and so forth. Each letter of the alphabet is rotated 13 times "forward" to be encrypted. And since the English alphabet contains 26 letters (13*2=26), running the same process again actually decrypt whatever text was encrypted. Obviously this encryption can be easily defeated by anyone and shouldn't be used for anything truly confidential.
