Need to add RSA encryption + decryption below AES

The current UI for AES and RSA is a bit messy. A cleaner UI would be appreciated.

Just make site better for mobile view! Maybe add some media queries

Add a plus button above the textbox for chaining multiple encodings/hashing (leave encryptions for now).
Example:
MD5 + SHA256 + BASE64
Comment if you need more help explaining the issue.

Currently, all inputs in AES should be Base64 encoded, and the output will be Base64 encoded too. Add small icons in the bottom right of input/output for entering input(data, key, iv) in hex/ascii/base64.

For RSA node-rsa library is used.
https://www.npmjs.com/package/node-rsa

The first thing to add is a custom public/private key while encrypting. (Don't remove the option to generate a new pair)

Secondly, node-rsa offers the following format schemes which should be incorporated

Add HMAC-SHAs and HMAC-MD5

There should be a button to clear all chaining so that user will not have to refresh the page
