- | 2. In RSA, the roles of the private and public keys can be reversed: you can encrypt with either key, and the other key (and only that key) can decrypt the message. | + | |
- | + | | |
- | 3. If someone encrypts a message with their **private key**, it can be decrypted using their **public key**, thereby verifying the authenticity. | + | |
- | + | | |
- | 4. The entire document is encoded as part of the signature (the encoded document itself is the signature). | + | |
- | + | ||
- | 5. The signer cannot deny having signed the document because they are the only ones who know the private key necessary to create the signature. | + | |

- | 6. When using the RSA signing method, the document remains unreadable until the signature is verified. | + | |
