Hash and Salt

Matt Gemmell vulgarizing hashing private data after the Path fiasco: 

If you’re a developer who’s implementing a social network, please do these things:

  1. Educate yourself about hashing; it’s real, and very useful. Use hashing for personal info. Do the hashing client-side, and only upload hashed data for comparison on the server.
  2. Delete the hashed data after you’ve done your fancy friend-matching stuff, because your users value their privacy, and you probably don’t even need to keep the data anyway.

Matt Gemmell addresses this problem in a simple and elegant way (as usual).
