Looking for some help with the AS3Crypto lib…I have a secret key that was sent to me as a file so I can encrypt some xml data using Blowfish. How do I access the key so that I can use it with AS3Crypto? I assume I need to Embed it using the [Embed] meta tag. It’s mimeType=“application/octet-stream” but I’m not sure if thats right. How do I embed, then reference this file as the secret key?  
As a bonus, if anyone has experience using the lib to work with the Java implementation and knows the ideal mode/padding/IV to use that would be awesome. Thanks!

Thanks!
