public void encrypt(Document document) throws Exception {
KeyStore ks = getKeyStore();
X509Certificate certificate = getCertificate(ks);
String algorithmURI = XMLCipher.SHA256;
Element rootElement = document.getDocumentElement();
XMLCipher xmlCipher = XMLCipher.getInstance(algorithmURI);
xmlCipher.init(XMLCipher.ENCRYPT_MODE, certificate.getPublicKey());
EncryptedData encryptedData = xmlCipher.getEncryptedData();
KeyInfo keyInfo = new KeyInfo(document);
encryptedData.setKeyInfo(keyInfo);
xmlCipher.doFinal(document, rootElement, true);
}
The keystore is provided from the example of xml-security. The exception is
Original Exception was java.security.NoSuchAlgorithmException: Cannot find
any provider supporting SHA-256
at org.apache.xml.security.encryption.XMLCipher.getInstance(Unknown
Source)
at org.jtang.service.security.engine.SecurityEngine.encrypt(
SecurityEngine.java:117)
I don't know how to solve it.
