Secret Emails and SMS/TEXT Messages on iPhone
secretTEXT application is perfect for scrambling/encrypting text. Simply type in the message that needs to be encrypted and the key that has to be used to decrypt it. You can copy it and email or text it.
When you get an encrypted message from another person, simply paste it in ‘Decrypt’ tab. After you also paste the key, just simply tap decrypt.
For more information, please visit secretTEXT official page:

Shmoocon 2010: Cracking the Foundation: Attacking WCF Web Services 5/5
Clip 5/5
Speaker: Brian Holyfield
Hacking a web service generally isn’t rocket science. But what if the web service requires messages to be sent using a binary protocol? What if it requires message level encryption but you don’t have a key?
These are just a few common scenarios you are likely to encounter when trying to attack a web service built with Windows Communication Foundation (WCF). Through a series of live demonstrations, the presentation will show how to identify and attack WCF web services.

In public-key encryption, how come the private key cannot be derived from the public key?
In public-key encryption, how come the private key cannot be derived from the public key? This is the question.
Also, I have another question. I saw on Wikipedia that some public-key encryption systems encrypt a message using a private key and then the receiver of the encrypted message decrypts it using the public key. Now, wouldn’t that be stupid? If the public key is used for decryption then anybody could decrypt your messages. Right?
Thank you!
Theoretically, you could derive the private key from the modulus that makes up part of the public key. The reason why this isn’t really possible in reality is because it would involve factoring an extremely large composite number, and there are no good algorithms known for doing this — "good" in the sense that they can efficiently factor a composite number. In reality, it would take supercomputer power for a long time to do it.
Regarding your second question, the reason why someone would do what you’re describing is to authenticate a person and text. This is called "signing." For a very simple example, I could send you an email and compute a one-way hash of the entire email. Then I could encrypt that one-way hash result with my private key. When you received the email, you could decrypt the encrypted one-way hash and compute it yourself, too. If the values matched, then you know not only that it was me who sent you the email (since only I have my private key), but also that nobody changed the text of the email while it was being transmitted.
