Risks associated with the use of Base64 encoded URLs in relation to security

When accessing my API from a web application, I'm using ajax to send get and post requests.

Since I'm new to this, I'm curious about the security implications related to the content type being used.

Currently, I know of two content types that can be used for POSTing data:

  • Base64encoded URL.

  • JSON

If I send the data as an encoded URL, it will be visible in the query string.

Even though Base64encoding is used, is it still a risky method for sending sensitive information?

I've read several articles stating that using JSON or URL encoding doesn't have a significant impact on security.

What specific security risks should I be aware of when considering the content type for transferring data between the application and the API?

Answer №1

Base64Encode/Decode should not be relied upon for secure data encryption or transfer. It can be used to transmit strings with special characters without disrupting protocols or functions, as discussed here.

In situations requiring security, it is recommended to use SSL for establishing a safe and encrypted connection between server and client.

Additionally, consider employing the RSA Encryption method to encrypt data before transmission (used by SSL).

When dealing with APIs, another crucial aspect to address is (Sniffing Security). Implementing a security layer like HMAC can help verify data integrity throughout its journey.

These are fundamental security recommendations. To delve deeper into this topic, search for terms such as HMAC, Hash, RSA Encryption, and SSL Certificate.
