The maximum number of times you would need to guess-and-check different keys for the cipher before cracking it is; 25 times
The Caesar Cipher is a type of shift cipher. Shift Ciphers work by using the modulo operator to encrypt and decrypt messages. The Shift Cipher has a key K, which is an integer from 0 to 25.
To encrypt a message, you just enter the message in the Plaintext textbox, specify the shift, and click Encrypt. However, to decrypt a message, enter the message in the Ciphertext textbox, specify the shift, and click Decrypt.
Now, For Caesar's Cipher there are only 25 possible ways to shift the alphabet and as such that is the maximum number of times you can guess and check.
