Taking your ideas for my next linux app

A gui app that lets you:

• symmetrically encrypt and decrypt text and files with AES-256 and without any weird formating that would make it incompatible with openssl.
• generate (without writing to file) RSA-(2048-4096) keys and asymmetrically encrypt, decrypt, sign and verify text and files.

It should be simple without any advanced options or storing any data or credentials or saving anything without asking the user. For example;

For symmetric text:

• 3 text boxes, 1 for input, 1 for output, 1 for password, encrypt/decrypt radio, 1 button.

For symmetric file:

• file picker, 1 password text box, encrypt/decrypt radio, 1 button

For asymmetric generation:

• 2 text boxes, 1 for priv key, 1 for pub key, 1 button.

For asymmetric text:

• 3 text boxes, 1 for input, 1 for output, 1 for priv/pub key, encrypt/decrypt/sign/verify radio, 1 button

For asymmetric file:

• file picker, 1 priv/pub key text box, encrypt/decrypt/sign/verify radio, 1 button
