Advanced Cipher/Decipher Tool

This cipher finds each input character in the Public Key, calculates a shift using the formula (where x = character position: 1, 2, 3...), then moves right (positive result) or left (negative result) through the Public Key.

To encrypt or decrypt your message:

• Enter your text in the input field
• The public key defines your character set (default: a-z)
• The formula calculates shift: positive = move right, negative = move left
• Click Cipher to encrypt or Decipher to decrypt (use same key and formula)
