ABSTRACT:
Signatures for multiple encodings is disclosed. In some embodiments, signatures for multiple encodings includes receiving a first signature of digitally signed data included in a first document having a first document encoding; receiving a second signature of digitally signed data included in the first document having a second document encoding; receiving a third signature of digitally signed data included in a canonicalized version of the first document having a canonical encoding, in which canonicalizing the first document includes providing a different order of data within the first document based on a canonical ordering; selecting a signature from the received first signature, the received second signature, and the received third signature, in which the first signature, the second signature, and the third signature are associated with the first document to provide a digitally signed first document; and verifying the digitally signed data using the selected signature.
