?How to use digital signatures in InfoPath

When you design a form template, you can specify whether users can add digital signatures when they fill out a form that is based on your form template. You can also specify whether users can sign the entire form or only part of the form. If you enable digital signatures so that they can be added to part of the form, you must specify that the data in the form can be signed. In addition, you can associate that data with a section that you add to your form template. After signing, the form or part of the form that was signed cannot be changed without invalidating the signature.

When designing a form template, you can also specify whether users are allowed to add multiple digital signatures to a form, and whether the signatures are co-signed (in this case independent of each other) or signed by an endorsement (in this case status of each signature is the signature of the form, in addition to the previous signatures)

:Digital Signature

Among these means of protection is the emergence of the concept of a digital signature, which has an important matter in our time with the technical progress that we are witnessing. Digital has certain types of encryption to ensure authentication. Encryption is the process of taking all the data that one computer sends to another device and encoding it in a way that only the other computer can decipher. Authentication is the process of verifying that this information comes from a trusted source. These two processes work in tandem. combined to produce digital signatures.

Basically, the idea of digital signatures is the same as in the traditional signature that we do by hand, where we use it to certify or document the fact that we promised something, and we can not go back on it later, the digital signature does not involve signing something using pen and paper. That's sending it over the Internet, but like a signature on paper, it sticks to the identity of the signatory on a transaction.

Hashing is one of the basic elements of a digital signature system. Hashing involves converting data of any size into fixed-size output. This is done by a special type of algorithm known as hash functions. The output generated by the hash function is known as the hash value or message digest.

When combined with cryptography so-called cryptographic hash functions can be used to generate a hash value (abstract) that acts as a unique digital fingerprint. This means that any change to the input data (message) may result in a completely different output (hash value). This is why cryptographic hash functions are widely used to validate digital data.
