Caesar cipher
Caesar cipher
Let's use a simple encryption algorithm called Caesar cipher. In this encryption technique, each letter in the plaintext is shifted a certain number of positions down the alphabet.
For example, we'll use a shift of 3. Here's the original poem:
"The Maze of Life
We enter the maze of life With curiosity and wonder We face the choices and challenges That await us in the center
We follow our instincts and emotions As we discover new paths and patterns We learn from our mistakes and missteps As we earn our rewards and lessons
We meet other travelers and guides Who share their wisdom and stories We connect and intertwine with them As we reflect on our own glories
We sometimes feel lost and confused As we encounter twists and turns We sometimes fear the unknown and unseen As we venture through the labyrinths
But we always find a way out As we reach the exit or the prize We always feel a sense of peace As we gaze at the clear blue skies
We realize that the maze of life Is a grand and mystical design We understand that the maze of life Is a journey of the heart and mind"
Now, applying the Caesar cipher with a shift of 3, each letter will be replaced with the letter that appears three positions down the alphabet:
"Zkh Pdhv ri Olih
Zh hqwduh wkh pdhv ri olih Zkdw frxogrzq wkh flih dqg zrqghu Zh idfh wkh flskhuv dqg fkdqqhov Wkdq dwdqg xv wkh fhduhu
Zh irxqg ruh wklv wlphv dqg rshqwhu Dv zh grzq wkh plvwdo vskhu lv sohdvhqhg Zh ohduq iru wkh pdnvdohv dqg plvwdqwv Dv zh hdus ruh uhvsrqv dqg ohvvhv

To decrypt the encrypted text, you simply shift each letter three positions up the alphabet.
I hope this helps you understand the Caesar cipher encryption technique.
Encrypt with numbers starting a is 1 b is 2 etc
In that case, we can use a variation of the Caesar cipher where each letter is replaced with its corresponding numeric position in the alphabet.
Here's the original poem with the numbers assigned to each letter:

In order to decrypt the text, you would need the corresponding alphabet letters for each number. For example, 1 corresponds to 'a', 2 corresponds to 'b'
