Hi, I am trying to decrypt a document that is encrypted using AES192 and in which the symmetric key is encrypted using an RSA key.
But decryption fails with the following exception. I get the same errors even if the document is encrypted using DESede. XMLCipher - Constructing XMLCipher... XMLCipher - Initializing XMLCipher... XMLCipher - opmode = UNWRAP_MODE XMLCipher - Decrypting key from previously loaded EncryptedKey... JCEMapper - Request for URI http://www.w3.org/2001/04/xmlenc#rsa-1_5 JCEMapper - Found RSA/ECB/PKCS1PADDING from provider BC JCEMapper - Request for URI http://www.w3.org/2001/04/xmlenc#rsa-1_5 JCEMapper - Found RSA/ECB/PKCS1PADDING from provider BC XMLCipher - JCE Provider = BC XMLCipher - JCE Algorithm = RSA/ECB/PKCS1PADDING org.apache.xml.security.encryption.XMLEncryptionException: unknown block type Original Exception was java.security.InvalidKeyException: unknown block type at org.apache.xml.security.encryption.XMLCipher.decryptKey(XMLCipher.java:1265) ... 9 more The code that it fails in is given below. cipher = XMLCipher.getInstance(); cipher.init(XMLCipher.DECRYPT_MODE, null); EncryptedData encryptedData = cipher.loadEncryptedData(doc, element); EncryptedKey ek = encryptedData.getKeyInfo().itemEncryptedKey(0); CipherValue encryptionKeyCipherValue = ek.getCipherData().getCipherValue(); XMLCipher keyCipher = XMLCipher.getInstance(); keyCipher.init(XMLCipher.UNWRAP_MODE, rsaprivatekey); String algo = encryptedData.getEncryptionMethod().getAlgorithm(); key = keyCipher.decryptKey(ek, algo); // fails here The encrypted document is as follows: <xenc:EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"; xmlns:xenc="http://www.w3.org/2001/04/xmlenc#";> <xenc:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes192-cbc"; xmlns:xenc="http://www.w3.org/2001/04/xmlenc#"; /> - <ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#";> - <xenc:EncryptedKey xmlns:xenc="http://www.w3.org/2001/04/xmlenc#";> <xenc:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-1_5"; xmlns:xenc="http://www.w3.org/2001/04/xmlenc#"; /> Could anybody point me to what could be going wrong? I am using BouncyCastle JCE and Xalan 2.5. Thanks much for any help, Sachin. __________________________________ Do you Yahoo!? Yahoo!
