Hi @josoroma,

To sign PDF documents the LibreSign use PKCS#12, is the standard to put the cryptographic elements of document in a place of the PDF.

To sign non PDF files is necessary use the PKCS#7 standard. Using this standard, is common archive the cryptographic elements of signature and to validate the file on file with extension .p7s.

On server side PKCS#7 was partially implemented but we need time to implement this because isn't API changes, will be necessary change the frontend on the moment to sign the file and on the moment to validate the file and we will need funding to do this on frontend.
