RSA Encryption Tool is a tool used for encrypting and decrypting text. It uses the RSA encryption algorithm and can encrypt text using a public key, decrypt text using a private key, or sign text using a private key.

Features:

1. Input the text to be encrypted or signed.

2. Input the public key or private key.

3. Select the type of key to be used (public or private).

4. The tool will use the selected key type to encrypt, decrypt, or sign the text.

5. The tool will output the encrypted, decrypted, or signed text.

Use cases:

1. Data encryption: During data transmission, using the RSA Encryption Tool can encrypt sensitive data to protect its security.

2. Digital signature: Using the RSA Encryption Tool can sign text to ensure its integrity and authenticity.

3. Secure communication: Using the RSA Encryption Tool can encrypt communication content to ensure its security.

4. Database encryption: Using the RSA Encryption Tool can encrypt sensitive data in a database to protect its security.
