For the purpose of ensuring clarity and security, every web application that includes the functionality of digital signing must conform to the following two requirements. The requirements inter alia arise from the European Union directive concerning digital signatures.
- Before giving a signature in a web application, the user must be able to examine the data in a reasonable manner.
- After giving a signature, the user must be able to examine what he or she signed, i.e. to download the DigiDoc container along with the initial signed data and signatures.
