Why Not SSL Everywhere?

• Cost
• Setup
• Performance impact
• Mixed-content warnings
• Third-party content (ads, analytics)
• User-embedded content
• CDNs (CNAMEs)

encode.c

Simple exercise for learning C:

• Reads text from STDIN
• By default, rotates all text by one character ("abc" => "bcd")
• Prints to STDOUT
• If the "-n [number]" flag is supplied, rotate by that many characters
• If the "-d" (decode) flag is supplied, rotate in the opposite direction
• If the "-f [filename]" flag is supplied, read from that file rather than STDIN
