XAdES (XML Advanced Electronic Signature) is an XML-based signature format defined in the ETSI 101 903 standard. The XAdES signature results in an XML file. The XML file can display the signature properties and content in sections.
XAdES Signature Structures:
This signature structure is similar to the attached signature in CAdES. In this structure, the signature includes the signed content itself.
It is similar to the detached signature in CAdES. The signed content is separate from the signature. URI of the signed content is also signed. For this reason, it should be ensured that the file path can be run in a uniform manner for each user. A detached signature is a signature format that makes signing of large size of files effective.
As stated in ETSI TS 101 903, XAdES signature types are subdivided according to the validity period and the data it contains. These are BES, EPES, ES-T, ES-C, ES-X Type 1, ES-X Type 2, ES-X Long Type 1, ES-X Long Type 2 and ES-A.
