Electronic Signature

Can digital signatures be copied?

Short answer. No. It is not possible to copy a digital signature.

Long answer. Also no. A digital signature is a mathematical technique used to guarantee the authorship and integrity of a message or a piece of data. It could be any kind of data. When it comes to Oneflow, it’s contracts But it could be anything else that requires verification. Such as verifying an email, or signing a form to pick up a package.

Digital signatures can’t be copied for a variety of reasons. Chief among them is that they use Public Key Infrastructure (PKI) for creating and validating digital signatures. When it comes to PKI, a private key is used to sign the message, and then a public key is used to validate the signature. That private key is unique and attached to the person who is signing it and cannot be replicated by anyone else. After signing, a certificate is issued by a trusted third party called a Certificate Authority. That is used as proof that the holder of the private key is actually who they claim to be.

How do digital signatures work?

Digital signatures work the same exact way that handwritten signatures do. They are unique to each person. Digital signatures adhere to the standard format of PKI. PKI states that the document provider, in this case, Oneflow, uses an algorithm to create a number sequence which are called keys. One public and one private key are created during each digital signature. The private key is used to sign, while the public key is used to verify. 

Every time a person signs a document electronically, the signature is created using the signer’s private key. This is securely contained by the signer. During the signing process, the algorithm becomes the cipher with which it matches the data from the signer with the signed document, then encrypts it. The encrypted data is the digital signature. The signature is recorded with a date and time stamp for that document, and if any changes are made to the document after signing, the digital signature is no longer valid. 

Maintaining the integrity of the digital signature is vitally important. According to the terms set out by PKI, the keys must be created, conducted, and saved in a secure manner that requires a reliable Certificate Authority. Oneflow meets all the PKI requirements for safe and secure digital signatures.

Can digital signatures be edited?

Again, no. Digital signatures have a secure system in place to ensure accuracy and prevent forgery from occurring. This is again due to them using industry-standard PKI and a Certificate Authority.
