问题 I am working on a mobile application(ionic) where there is a field for user's signature. Users needs to sign with their finger in canvas. Now this application has web version, where they used topaz sigweb to do this. Now to save signature and to view in both ends i need some kind of conversion. I checked sigweb's documentation, they save the signature in ASCHII hex format. I am not sure if they are using any kind of internal encryption or not because i can not convert the hex string to any

From what I read you need the data from the signature being created (time stamp, pressure and time from drawing) and attach it to the PDF. But is this enough? So to open a canvas, read the data and attach it to the PDF with the signature image itself or do I need to digitally sign the PDF as well? If this is it enough, then where to attach all
