示例1: getAlgorithmIdentifier
import org.bouncycastle.asn1.x509.SubjectPublicKeyInfo; //導入方法依賴的package包/類
protected static AlgorithmIdentifier getAlgorithmIdentifier(
PublicKey key)
throws CertPathValidatorException
{
try
{
ASN1InputStream aIn = new ASN1InputStream(key.getEncoded());
SubjectPublicKeyInfo info = SubjectPublicKeyInfo.getInstance(aIn.readObject());
return info.getAlgorithmId();
}
catch (Exception e)
{
throw new ExtCertPathValidatorException("Subject public key cannot be decoded.", e);
}
}

// SignedPublicKeyAndChallenge ::= SEQUENCE {
