The sxml file extension identifies an XML document protected in sealed, encrypted form. The file contains XML content, but that content is not normally readable as plain XML until the file has been unsealed.
Unsealer, developed by Oracle Corporation, is the software associated with this format. It is used to open and unseal files derived from xml documents. Unsealer is available for Microsoft Windows, and access to the document depends on the required authorization or decryption information.
MIME type:
application/vnd.sealed.xml
On Microsoft Windows, use Unsealer to open an sxml file. Launch the program and open the file through it; a standard text editor or XML editor cannot normally display the protected XML content.
To convert an sxml file, first unseal it with Unsealer. The resulting document may then be saved or exported as ordinary XML if the software provides that option and the required authorization is available.
