使用iTExt 5.3获取pdf签名

Posted 2021-02-24

This is a code snippet that retrieves the signatures from a pdf document and the reason for them. It does that in approximately 200ms for one signature.

PdfReader reader = new PdfReader("c:\sss.pdf");
		AcroFields fields = reader.getAcroFields();
		for (String signame : fields.getSignatureNames()) {
			System.out.println(signame);
			PdfDictionary sig = fields.getSignatureDictionary(signame);
			System.out.println(sig.getAsString(PdfName.REASON));
		}
