我尝试使用 iText 5.5.0 和文档示例进行签名:
private static void pdfSign(String srcFile, String dstFile) throws Exception
KeyStore ks = KeyStore.getInstance("pkcs12", "BC");
ks.load(new FileInputStream(PFX_ROUTE), PFX_PASSPHRASE);
String alias = (String)ks.aliases().nextElement();
PrivateKey pk = (PrivateKey)ks.getKey(alias, KEY_PASSPHRASE);
Certificate[] chain = ks.getCertificateChain(alias);
// reader and stamper
PdfReader reader = new PdfReader(srcFile);
PdfStamper stamper = PdfStamper.createSignature(reader, new FileOutputStream(dstFile), '\0');
// appearance
PdfSignatureAppearance appearance = stamper.getSignatureAppearance();
appearance.setVisibleSignature(SIGNFIELD_NAME);
appearance.setReason("Test");
appearance.setLocation("TestLocation");
ExternalSignature es = new PrivateKeySignature(pk, "SHA-1", "BC");
ExternalDigest digest = new BouncyCastleDigest();
MakeSignature.signDetached(appearance, digest, es, chain, null, null, null, 0, CryptoStandard.CMS);
}
我收到以下错误。

我的java版本是:
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
我正在使用 Netbeans IDE 7.4 和 JCE 无限强度管辖权策略文件，这些文件在我的/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/jre/lib/security 路径中替换。
我已经从我的终端尝试过“ulimit -c unlimited”命令。
最佳答案
我不知道为什么，我在另一个环境中尝试了我的代码，它给了我一个 BouncyCaSTLe 异常。我将 BC JAR 更改为 1.48 版本，它在我的 Windows 环境中正常工作。在我的 Unix 环境中，我在保存文件时遇到问题。
感谢大家
