why can not find the Algorithm about the SignedData?
I'm using the class SignedData of package Codec,and i add the BoundCastle provider.
The code followed:
import java.io.*;
import java.util.*;
import java.security.cert.*;
import java.security.*;
import codec.pkcs7.*;
import codec.Base64;
import codec.asn1.*;
import codec.x501.*;
class PFXSign
{
private SignedData sigdata_;
private codec.pkcs7.Signer signer_;
private SignerInfo siginfo_;
private X509Certificate cert_;
public void loadPFX(String pfxFilename, String passwd)
{
PrivateKey privatekey;
char[] storepass = passwd.toCharArray();
try
{
KeyStore ks = KeyStore.getInstance("PKCS12","SunJSSE");
FileInputStream fis = new FileInputStream(pfxFilename);
ks.load(fis,storepass);
fis.close();
// retrieve information from pfx certificate
Enumeration en = ks.aliases();
String alias = (String) en.nextElement();
//System.out.println("Contains " + alias);
cert_ = (X509Certificate)ks.getCertificate(alias);
//System.out.println(cert.toString());
privatekey = (PrivateKey)ks.getKey(alias,storepass);
//System.out.println(privatekey.getAlgorithm());
// init SignerInfo, Signer
siginfo_ = new SignerInfo(cert_,"SHA1WithRSA");
siginfo_.addAuthenticatedAttribute(
new Attribute(
new ASN1ObjectIdentifier("1.2.840.113549.1.9.5"),
new ASN1UTCTime()));
sigdata_ = new SignedData();
sigdata_.setData(null);
sigdata_.addCertificate(cert_);
signer_ = new codec.pkcs7.Signer(sigdata_, siginfo_, privatekey);
}
catch (Exception e)
{
System.out.println("Error: " + e);
}
}
private String sign(String docFilename)
{
ContentInfo info;
DEREncoder enc;
String sigString=null;
try
{
FileInputStream fis = new FileInputStream(docFilename);
signer_.update(fis);
fis.close();
signer_.sign();
System.out.println(sigdata_.toString());
info = new ContentInfo(sigdata_);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
enc = new DEREncoder(baos);
info.encode(enc);
enc.close();
byte[] sigBytes = baos.toByteArray();
sigString = Base64.encode(sigBytes);
}
catch (Exception e)
{
System.out.println("Error: " + e);
}
return sigString;
}
public static void main(String[] args)
{
if(args.length < 4) {
System.out.println("PFXSign pfxFilename password docFilename signFilename");
return;
}
PFXSign testSign = new PFXSign();
testSign.loadPFX(args[0],args[1]);
String sigString = testSign.sign(args[2]);
System.out.println(sigString);
try
{
FileOutputStream fos = new FileOutputStream(args[3]);
fos.write(sigString.getBytes());
fos.close();
}
catch (Exception e)
{
System.out.println("Error: " + e);
}
}
}
when i run it,it said "NoSuchAlgorithmException" at "siginfo_ = new SignerInfo(cert_,"SHA1WithRSA");"
how can i do?
thanks!
