Advanced vs Qualified Signature Delivery

Under European Union eIDAS regulations:

  • Qualified signatures—Issued on a USB token (QSCD) for individuals, offering the same legal validity as handwritten signatures.
  • Advanced signatures—Issued on a USB token (SCD) for individuals.

For certificates used for signing or sealing, when the author initiates the digital signature of the document, the signing application will create a HASH value that represents the entire content of the document. After the author authenticates, typically using a PIN, the HASH value is signed and embedded into the document itself. Any modification after signing alters the HASH value, rendering the signature invalid.

About

Electronic Signatures

The eIDAS regulation further distinguishes between advanced and qualified signatures and electronic seals.

An advanced electronic signature (AdES) or seal is based on a qualified certificate for electronic signatures, and has the following characteristics:

  • It is uniquely linked to the signatory.
  • It can identify the signatory.
  • It is linked to the signed data, allowing detection of any changes.

A qualified electronic signature (QES) or seal is a type of AdES that is created using a qualified electronic signature creation device and is based on a qualified certificate for electronic signatures or seals

As a Qualified Trust Service Provider (QTSP), Sectigo issues trusted certificates that comply with these regulations, ensuring secure and legally binding signatures.
