Alexey, I've used such a mechansims in Apache's WSS4J project:
- generate a symmetric key, e.g. for 3DES - encrypt some data with this key - uses RSA/ECB/PKCS1Padding to encrypt this symmetric key (not DESedeWarp, this would be used if you encrypt - wrap - a key with e.g. 3DES). Alternatively you may use RSA-OAEP (also provided by BC) to encrypt the generated symmetric key. The module in WSS4J that uses and implements this is WSEncryptEnvelop.java Regards, Werner Alexey wrote: > Werner Dittmann <Werner.Dittmann <at> t-online.de> writes: > > >>Alexey, >> >>with XMLCipher you can only encrypt/decrypt XML documents >>according to the W3c standard, using symmetric ciphers. >> >>You try to use a public key cipher (assymmetric), such a cipher >>is used to wrap the symmetric key. >> >>Regards, >>Werner >> > > > Hi Werner, > Actually I tried symmetric (3DES) with the same result.
