add name argument in \xmldoifatt
by Pablo Rodriguez 17 Jun '24

17 Jun '24

Hi Hans, I think NAME added should be added to all versions of \xmldoifatt (ifnot and ifelse). BTW, I’m afraid all three conditionals might be not working. The patch only fixes the explanation. Many thanks for your help, Pablo

patch to correct byterange for signatures
by Pablo Rodriguez 09 Jun '24

09 Jun '24

Hi Hans, I attach a patch for fixing the issue with hash wrong validation in signed documents (and another minor typo). Sorry for the long explanation, but I think this is required, since these is a sensible topic. A sample source: \setupinteraction[state=start] \definefield[signature][signed] \defineoverlay[signature][my signature] \starttext \startTEXpage[offset=1ts,frame=on,framecolor=darkblue] sign: \inframed[background=signature,framecolor=darkred] {\fieldbody[signature][width=3cm,option=hidden]} \stopTEXpage \stoptext After compiling it with ConTeXt, I run: mtxrun --script pdf --sign --certificate=c.pfx --password=ABCabc a.pdf (Certificate attached, passphrase is ABCabc.) I get a signed PDF document, but both pdfsig and mutool sign complain about disgest mismatch (as already mentioned on the other list). After investigating the issue, I realized that the /ByteRange was wrong calculated. Using a binary editor ("neovim -b", for that matter), I jumped to the final range of the first byte (value of n1 from getbyteranges()). I saw that the first byte range ended in the s of /Contents, but there was a blank space after it (before the hex string value). This causes the digest mismatch, because the tmpfile contained an extra space excluded in the first byte range. I modified the sigfile manually adding one more byte to the byte length and both pdfsig and mutool sign detected a valid signature. The patch was simple and now I realize the wrong byterange may have been well a typo in n1. (Excuse my verbose explanation in that case 😅.) Outputs from both pdfsig and mutool sign are fine after the patch: $ pdfsig a.pdf Digital Signature Info of: a.pdf Signature #1: - Signature Field Name: signature - Signer Certificate Common Name: John Doe - Signer full Distinguished Name: CN=John Doe,O=No Brainer [...] - Signing Time: Jun 09 2024 11:50:53 - Signing Hash Algorithm: SHA-256 - Signature Type: adbe.pkcs7.detached - Signed Ranges: [0 - 6426], [10524 - 10909] - Total document signed - Signature Validation: Signature is Valid. - Certificate Validation: Certificate issuer isn't Trusted. $ mutool sign -v a.pdf Verifying signature 3: Distinguished name: cn=John Doe, o=No Brainer, ou=, email=, c=XX Certificate error: Self-signed certificate. The document is unchanged since signing. I think the patch may be considered to be included in next latest. Many thanks for your help, Pablo
