It says: Digital Signature Info of: pdfsig_error_coredump.pdf Signature #1: - Signer Certificate Common Name: MICHAEL ANDREY VARGAS BARRANTES (FIRMA) - Signer full Distinguished Name: CN=MICHAEL ANDREY VARGAS BARRANTES (FIRMA),OU=CIUDADANO,O=PERSONA FISICA,C=CR,givenName=MICHAEL ANDREY,SN=VARGAS BARRANTES,serialNumber=CPF-03-0394-0670 - Signing Time: Jul 04 2017 21:33:17 - Signing Hash Algorithm: SHA-256 - Signature Type: ETSI.CAdES.detached - Signed Ranges: [0 - 122708], [166258 - 171742] - Not total document signed - Signature Validation: Signature is Valid. - Certificate Validation: Certificate issuer isn't Trusted. However, the "- Not total document signed" part is a bug. I'll fix this with a revised patch. > > pdfsig does not crash without the patch, it just says > > "Unimplemented Feature (0): Unable to validate this type of signature". > > Patched pdfsig says: > > "Signature #1: > - Signer Certificate Common Name: XXXXXXXXXXXXXX > Segmentation fault (core dumped)" > > It does get the Common Name correctly. > > Cheers Concerning your crash, have you pulled the latest state of the master branch before applying the patch? What processor architecture and system (32-bit or 64-bit) are you working on? I tried pdfsig on an i386 (32-bit) system and had no crash as pointed out above.
