GRASShopper is a program verifier that ensures that programs are memory safe. I wrote an FTP client and server in SPL, the GRASShopper programming language. SPL integrates the program logic's pre- and post- conditions, along with loop invariants, into the language, so that programs that compile in GRASShopper are proven correct. Because of that, my client and server are guaranteed to be secure and correct. I am supervised by Professor Martin Rinard and Dr. Damien Zufferey, a post-doctoral researcher in Professor Rinard's laboratory.</dim:field>
