How safe is a digitally signed PDF document?
In order to add electronic signatures to your Word documents, you’ll need a signing certificate. This digital certificate is what confirms your identity. It’s included (along with a public key) when you send a digitally signed document. Digital certificates can be obtained in one of two ways. You can receive a certificate from a third-party authority or create your own personal certificate. While a third-party certificate is more official, creating your own can be convenient.

Modify PDF: All You Need to Know
This is very easy to validate in practice. It makes the signature useless in any crypto context. Since the secret key is tied to the public key, nobody else can read the message, and thus it can be encrypted with the private key, making it untouchable. If someone is trying to get at your public key, they will have to figure out how to crack your signature, since they already know the public key, and are familiar with the algorithm that deciphers the message. You have lost control over that secret key. Your private key is your most prized possession. It is the one thing everybody wants to protect, even when they are doing so at your expense. What if someone tries to reverse engineer or steal your private key? They could use a very sophisticated ENCRYPTING algorithm like PEM or RSA to decrypt your key and do all.
