If I send the encrypted email to someone, can I see them? ubi: Sign is a custom software for digital signature and document encryption used by Java Web Start technology, which is a helping application associated with a web browser and allows the provision of autonomous Java software applications on the web. When a user clicks on a link to a special start file (i.e. a JNLP file), the browser launches Java Web Start, which automatically downloads, stores and executes the specified java application. The entire process is complete without the user`s interaction being required, except for the first click. From a technological point of view, Java Web Start inherits a number of important advantages for ubi:sign: Here are some common reasons for applying a digital signature to communication: As I said before, this article is that I`m trying to do my part to move the company from paper to digital. If you want to help, please take a few minutes to share this with someone else. Technically, a digital signature applies to a set of bits, while people and applications “believe” that they sign the semantic interpretation of these bits. To be interpreted semantically, the bit sequence must be converted into a form useful for humans and the application, and this is done through a combination of processes based on hardware and software on a computer system. The problem is that the semantic interpretation of bits can change depending on the processes used to convert bits into semantic content. It is relatively easy to change the interpretation of a digital document by implementing changes to the computer system on which the document is processed. From a semantic point of view, this creates uncertainty as to what has been signed. WYSIWYS (What You See Is What You Sign)[31] means that the semantic interpretation of a signed message cannot be changed.

In particular, this means that a message cannot contain hidden information that the signatory does not know and that can be disclosed after using the signature. Wysiwys is a prerequisite for the validity of digital signatures, but this requirement is difficult to guarantee due to the increasing complexity of modern computer systems. The term WYSIWYS was coined by Peter Landrock and Torben Pedersen to describe some of the principles of providing safe and legally binding digital signatures for pan-European projects. [31] What is a digital signature and how to create it? Several early signature patterns were similar in nature: they include the use of a trapdoor permutation, such as the RSA function, or in the case of the Rabin signature card, composite of the square computer module, N. A trapdoor permutation family is a family of permutations, expressed by an easy-to-calculate parameter towards the front, but difficult to calculate in the opposite direction without knowing the private key (“Trapdoor”). Trapdoor permutations can be used for digital signature diagrams where the reverse direction calculation with the secret key of the signature is required and where the forward direction is used to verify signatures. If you save a document and run it with your public key via an algorithm, you will receive an encrypted document or an encrypted email. I still haven`t figured out how the receipt would find if the hash encryption (which should be used to confirm that the message hasn`t been changed) was changed during transmission? Digital signatures should not be confused with digital certificates.
