Hello, I’m developing an application in PHP that Feature would have to sign documents digitally with the A1, I know that under desktop This is much easier, but I want to do it in PHP.
I already signed with TCPDF example 52, and would like to know on the basis of the signature made by TCPDF, how can I validate it and take the data from the digital signature.
The code I used is the same as in the above example (TCPDF).
You want, with PHP, to take the digital signature generated by TCPDF, this?
