Hi! Welcome to the Caesar Cipher API :). This API it's an implementation of this basic encryption algorithm.

It's really simple. The API expects a json with the following structure

{
    "shift": int,
    "content": str
}

where shift it's the shift you want to apply to the alphabet and content the message you want to encrypt/decrypt

Important: We only support messages in spanish with letters. If you use a number or special mark such as ! @ # ... the API will return an error. Another thing to mention is that all the messages are capitalized.

This API has two endpoints - or 3 if you count the root one - which are: encrypt and decrypt. I think it's clear what each endpoint do. For both, you just need to pass a json with the structure we already saw

Let's say we want to encrypt the message "ZAPATO" with a shift=10. In that case we just need to POST to encrypt the following json

{
    "shift":10,
    "content":"ZAPATO"
}

And we'll get this response from the API

{
    "message":"JKZKDY"
}

If now we want to decrypt that message we need to do the same thing, but with decrypt

{
    "shift":10,
    "content":"JKZKDY"
}

And the API will return

{
    "message": "ZAPATO"
}

That's all! Enjoy using our API :D
