示例1: buildPublicKey
import org.spongycastle.asn1.ASN1Primitive; //导入依赖的package包/类
static PublicKey buildPublicKey(byte[] rawBytes) throws CryptoException {
try {
//FIXME replacing X509EncodedKeySpec because of problem with 8.1
//Since 8.1 Bouncycastle cryptography was replaced with implementation from Conscrypt
//https://developer.android.com/about/versions/oreo/android-8.1.html
//either it's a bug in Conscrypt, our public key DER structure or use of X509EncodedKeySpec changed
//alternative needed as this adds expensive Spongycastle dependence
ASN1InputStream bIn = new ASN1InputStream(new ByteArrayInputStream(rawBytes));
SubjectPublicKeyInfo info = SubjectPublicKeyInfo
.getInstance(new ASN1InputStream(bIn.readObject().getEncoded()).readObject());
DLSequence dlSequence = (DLSequence) ASN1Primitive.fromByteArray(info.getPublicKeyData().getBytes());
BigInteger modulus = ((ASN1Integer) dlSequence.getObjectAt(0)).getPositiveValue();
BigInteger exponent = ((ASN1Integer) dlSequence.getObjectAt(1)).getPositiveValue();
RSAPublicKeySpec spec = new RSAPublicKeySpec(modulus, exponent);
KeyFactory kf = getRSAKeyFactory();
return kf.generatePublic(spec);
} catch (InvalidKeySpecException | IOException e) {
throw new CryptoException(e);
}
}
示例2: sign
import org.spongycastle.asn1.ASN1Primitive; //导入依赖的package包/类
@Override
public byte[] sign(InputStream content) throws IOException
{
CMSSignedDataGenerator gen = new CMSSignedDataGenerator();
SignatureData input = new SignatureData(content);
List<Certificate> certs = new ArrayList<Certificate>();
for (int i = 0; i < chain.length; i ++) {
certs.add(chain[i]);
}
try
{

org.spongycastle.asn1.x509.Certificate x509Cert =
org.spongycastle.asn1.x509.Certificate.getInstance(ASN1Primitive.fromByteArray(cert.getEncoded()));
ContentSigner sha256Signer = new JcaContentSignerBuilder("SHA256withRSA").build(privKey);
gen.addSignerInfoGenerator(
new JcaSignerInfoGeneratorBuilder(
new JcaDigestCalculatorProviderBuilder().build())
.build(sha256Signer, new X509CertificateHolder(x509Cert)));
gen.addCertificates(certStore);
CMSSignedData signedData = gen.generate(input, false);
return signedData.getEncoded();
}
catch (Exception e)
{
e.printStackTrace();
}
throw new RuntimeException("Signing error, look at the stack trace");
}
