Using PyCrypto with Spring Crypto/Spring Security Default Encoders

Spring Crypto Encryptor Details The Spring Crypto module is amazing. Secure defaults using standard interfaces really make it a pleasure to use, and with it being full tested and vetted, it also gives a develoepr the warm fuzzy feelings of nice Java security implentation. The standard interface is through the  org.springframework.security.crypto.encrypt.Encryptors class, defined (in version 3.2.0 here (the class API to which this blog post was written in July 2016). Spring Crypto uses AES256 encryption behind the scenes in its out of the box class setup; it's as easy as: In the above code snippet, the password  variable is a passcode, with the salt  variable used to create the AES key. It uses 256 bit encryption with the standard calls (depending on your JRE/Java Cryptography Extension (JCE) Setup, make sure to download the appropriate extension ). The default AESBytesEncryptor setup generates a 256 bit key (32 bytes) from a salted iteration done 1024 times. Another th

So, oftentimes on my iphone I would unlock it and my ipod controls would come up. I thought it was a bug for a long time, since the controls went away so fast... but it is a feature!

It turns out you can access the iphone ipod controls while the phone is locked or in a different menu than the ipod interface by double-tapping the home button! So, double tapping to wake goes directly to the ipod interface pause button... handy when people are trying to talk to you and you're listening to music! You can also double tap from any interface and the ability to fast-forward/rewind/pause comes up. Neat-o.

Are undocumented features like this a reason to upgrade your firmware? This is only a iphone 1.1.1 September 2007 update feature or something.

If you're slow, that means I'm molasses. Did you see it documented anywhere?
