Validating html file
You can change the trust settings of certificates to allow specific actions.
For example, you can change the settings to enable the dynamic content and embedded Java Script within the certified document.
When you receive a signed document, you may want to validate its signature(s) to verify the signer and the signed content.
Depending on how you have configured your application, validation may occur automatically.
In addition to providing instructions, validate user input to help users avoid mistakes.
HTML5 defines a range of built-in functionality to validate common types of input, such as email addresses and dates.
A digital ID is required to add the certifying digital signature.
Also, HTML5 validation helps users inputting data by providing specific controls, such as date pickers and custom on-screen keyboards.
These timestamps are compliant with the timestamp and revocation features described in Part 4 of ETSI 102 778 If the signature status is unknown or unverified, validate the signature manually to determine the problem and possible solution.
If the signature status is invalid, contact the signer about the problem.
When the form is complete, the agency certifies the document, allowing users to change only form fields and sign the document. However, if they remove pages or add comments, the document doesn’t retain its certified status.
You can apply a certifying signature only if the PDF doesn’t already contain any other signatures. A blue ribbon icon in the Signatures panel indicates a valid certifying signature.
