SecuSend - Software for secure file sharing.

@40hz - Good question. As for encryption method you can check Techical Specification section. I have just released beta version of a product and it's a good time to think about user level of trust. Talking about similar product on the market (closed-source) I think Trust is based on the company "size" and "persona" and probably on software analyzing from crypto experts.
It's a great question to think about.
Thanks.
f0dder:
Decent idea, and looks like a user friendly interface.
Some questions:
What's TDEA? Another name for triple-DES? (And why include such an algorithm?)
Which mode is AES used in? (CBC, XTS, ...?)
Why MD5 for hash?
Which public-key algorithm is used, and which bitsize? Which PRNG, and how is it seeded?
Are both file contents and filenames encrypted? Is any compression involved?

Yes, Triple-DES. It's used as signature algorithm type in process of encoding enveloped data.
Which mode is AES used in? (CBC, XTS, ...?)
-f0dder (June 13, 2013, 09:45 AM)

AES with CBC mode with IV unpredictable at encryption time.
Why MD5 for hash?

Currently it's used for package integrity, but will be changed in the next version to the SHA.
Which public-key algorithm is used, and which bitsize?

RSA-2048
Which PRNG, and how is it seeded?

Microsoft CSPs is used as random number generator.

Yes, both contents and filenames encrypted. In this version compression is not involved, but it would be in the next version. Compression before encryption.
