Hello HN,<p>I wrote FreeOTP about a year ago. With the recent privacy concerns in the news, I wanted to share it with others and get feedback and suggestions.<p>An acquaintance of mine, who is a professor of math at Virginia Tech and who teaches cryptography, reviewed the code and encrypted and decrypted some messages, but we didn't do much with it after that.<p>It's alpha software, but it seems to work OK on Windows, Mac and Linux. I post test messages on twitter (user FreeOTP) with pads so that anyone can decrypt them. Would be neat if others would encrypt something and send me the pads and encrypted messages so I could experiment more.<p>Let me know what you think. Would really appreciate any feedback with regard to the crypto implementation.
