The Caesar cipher is an old encryption technique where each letter in a message is shifted by a fixed number down the alphabet (For example, we can replace A→D, B→E, and so on with a shift of 3). While historically used by Julius Caesar for military communications, it is completely insecure for modern use because its limited 25 possible shifts make it easily crackable within seconds. Modern encryption standards like AES use complex mathematical algorithms that are much more difficult to break. The Caesar cipher fails to protect sensitive information like medical records, financial data, or personal details. Healthcare professionals should never use such basic encryption as it violates patient privacy laws and fails to meet current cybersecurity requirements for protecting confidential information.
To encrypt, type something into the input box and click encrypt. To decrypt, copy and paste the encrypted output from the output box back to the input box and click decrypt.
