Seal

This program uses the RSA asymmetric encryption algorithm to encrypt and decrypt your text content. It features:

1. Management of public keys for multiple contacts, allowing switching between them at any time during encryption and decryption.

2. Saving encrypted and decrypted content for each contact as "Chat History," which can be managed separately or cleared with a single click.

3. Importing and exporting public and private keys can be done quickly and easily by scanning a QR code.

4. Automatic clipboard handling, or manual pasting.

While users can set a password to protect their private key from unauthorized export, they still need to ensure the physical security of their phone.
