Hi Joseph,

There are a lot of sample classes shipped with the Apache XML Security fra=
mework.=20

How to perform encryption and decryption is shown the classes Decrypter an=
d Encrypter in the package org.apache.xml.security.samples.encryption.

How to perform signature and verification is shown the classes CreateEnvel=
opingSignature CreateSignature and VerifySignature in the package org.apac=
he.xml.security.samples.signature.

We have used both BouncyCastle and IAIK as JCE providers and both worked f=
ine for us.

HTH,
Ulrich

Dear Ulrich

Thanks for your response and the advice. I am using Bouncy Castle as my
security provider. Is there some code that I can use as an example for wha=
t
I need=3F The public key is stored in a public key object in a database, so
there is no difficutly retrieving it.=20

Thanks and Regards
Joseph

Hi Joseph,

Sure is this possible. That's what Apache XML Security is all about, isn't=

it=3F :)

But I would first sign the message and encrypt it afterwards. That gives a=

hacker less information because all signature related information is in th=
e
encrypted part of the receipt.

Cheers,
Ulrich

Betreff: Encrypt with public key

Hi

I am writing an XML exchange program in which I would like a
mechanism if acknowledgements using encrypted XML receipts.

The receipt is an XML file simply stating that a message has
been received. It is sent by the receiver to the sender. I would like to
encrypt the message with the public key of the sender, and then signing th=
e
message with the private key of the receiver.=20

Is it possible to encrypt the message using the public key
with the Apache Encryption library=3F

Thanks for your help in advance.

Kind regards


Joseph
