How do you obfuscate an email?
Obfuscating email addresses on your website
- set up a mail form, (although that solution may still attract form spam)
- remove the mailto link and show their email address as an image (most likely to fool spammers)
- code the address as Javascript (which usually retains the mailto ability).
What is ROT13 function?
ROT13 (“rotate by 13 places”, sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the 13th letter after it in the alphabet. ROT13 is used in online forums as a means of hiding spoilers, punchlines, puzzle solutions, and offensive materials from the casual glance.
What is the encryption key for ROT13?
ROT13 (rotate 13) is a specific implementation of the Caesar cipher where the shift is 13 places. Due to the basic Latin alphabet being 26 characters long this means that the direction of the shift does not matter, the result is the same in either direction. They key (13) can be used without transformation.
How do I use ROT13 in Python?
ROT13 = Rotate the string to be encrypted by 13 positions (modulo 26) in the alphabet of 26 characters. If you want to encrypt a string, shift each character forwards by 13 positions in the alphabet. If you move past the last character “z”, you start over at the first position in the alphabet “a”.
How do I encrypt an email address?
Go to advanced settings and switch S/MIME on. Change “Encrypt by Default” to yes. When you compose a message and lock icon will appear next to the recipient. Click the lock icon so it’s closed to encrypt the email.

- Spelling it out.
- Adding a picture with contact details to the site instead of writing it out.
- Replacing some of the characters with words. For example, use [at] instead of @.
What is the difference between choosing Caesar and ROT13?
ROT13 uses the same mechanism as the Caesar cipher but moves each letter 13 places forward. The convenience of moving 13 places lies in the fact that applying another round of encryption with ROT13 also functions as decryption, as two rotations will return us to the original starting place in the alphabet.
What is the encryption key for rot13?
What is rot13 in Python?
ROT13 is a simple encryption method. It shifts each character of the clear text string 13 positions forward in the alphabet. Note: the variable cleartxt refers to the string you want to encode. It shouldn’t contain spaces, numbers or upper case letters!
