Sign Your Files

Certify your documents and files. Also your images and screenshots!

Easier Impossible

Certify with CASTLE Platform® Forensics the authenticity is very easy. Your information will be timestamped and a signature will be embedded into the metadata. Since this moment, your data will be trusted and it can be proven that it is not faked nor manipulated.

Upload the file

Upload the picture, screenshot or PDF you want to sign and time stamp. Just drag and drop.

Add extra fields

Optionally, you may add some extra fields for signing, such as your name, location, reason and contact info. All this data will be signed and appended to the file’s metadata. Additionally, you can add a watermark to make visible the signature. This watermark will contain a checksum for retrieving the time stamp.

Sign

CASTLE Platform® Forensics will sign your data and certify it with a legitimate time stamp.
