LibreOffice document with ECDSA signature
I have created a digitally signed LibreOffice document, where ECDSA signature
was calculated over the SHA-256 hash of canonicalized SignedInfo XML node. I
opened it with LibreOffice 5.3.0.3 but signature verification failed. On
low-level I could test the signature with OpenSSL v1.0.1c: result was "Verified
OK". (I also performed a negative test to be sure that OpenSSL works well.)
openssl dgst -sha256 -out SignatureValue_verified.txt -keyform PEM -verify
Aron_Szabo_end_signer-public_key.pem -signature SignatureValue_binary.txt
SignedInfo_to-be-hashed.txt
Could you check ECDSA support on low-level, under XMLSec Library? (I attached
test files...)
Relevant modules of my environment:
LibreOffice 5.3.0.3 (x64)
Windows 8.1 Pro (x64)
.NET Framework 4.6.2 (x64)
