Have you ever thought of investigating a concept that you don’t think about but use in day-to-day life? The concept of the digital signature is an excellent example of this situation.
Digital signature software is a term known to the general public, and there is no doubt in that. Further, it is already in use in many administrations and departments of human resources. Unfortunately, although there is a meeting with a potential client, some aspects of this technology are not as clear or understandable.
Have a look at these most asked questions about free digital signature software.
Are digital signatures safe?
Digital signatures are 100% safe, and it is also complicated to copy one.
That is because digital signatures are backed with blockchain integrity and have a private key, which only the signatory knows, and a public key, which is available to everyone. So when the user wants to sign a document, he uses his private key, which is unique and non-transferable.
In case of digital signature forgery occurs, the attacker would have to get the signer’s private key, which is extremely difficult. However, even if that happens, the user could revoke the trust in the key that has been compromised through another different key.
This means that if you want to use digital signature, you can rely on them for any procedure because it is very difficult to falsify them.
How do digital signatures work?
Digital signatures are basically digital certificates that are issued by CA or certification authorities. These are used to link digital identities to the pair of keys generated by the user and contain data like names, the date on which the certificate expires, a copy of the public key, and many more.
After that, the corresponding CA verifies the identity of each user; once it has been carried out, the said user can issue a digital certificate and sign the document they want.
In turn, digital signatures are based on blockchain integrity which consists of a public key and a private key.
So, when you want to sign a document, a hash is generated using a hash function. This hash is then encrypted using the signer’s private key and is combined with the public key to create a digital signature.
On the other hand, the receiver verifies the identity of the signatory through the public key, allowing full privacy of the information exchanged between the two users.
Can a document with a digital signature be trustable?
Yes, you can trust digital signatures easily! However, if there is a change in the document, the signature is no longer valid because the document has been modified, and the signed hash does not match the current one.
However, if the user’s private key has been compromised, the digital certificate can be revoked and no longer be used for signing.
