@bascule I've said it before, but I'll say it again; using CRC for security is like drinking O'Doul's for a buzz.

@justintroutman@bascule Serious question: Would you prefer CTR-encrypt-then-multiply-in-Galois-field instead? -
@marshray@justintroutman I'm a fan of "NaCl or GTFO" ;) -
@bascule@justintroutman I was talking about GCM, I believe NaCl has something similar. -
@marshray@justintroutman NaCl uses Poly1305 -
@bascule@marshray@justintroutman poly1305 uses prime field arithmetic, GCM and CRC use GF2.

@bascule@blaufish_ Yes, totally. Esp if you use XOR with a sekrit constant-cipher. The constant "justin bieber is sooo hot".Thanks. Twitter will use this to make your timeline better. UndoUndo

@bascule I sent the page maintainer a mail about it and mentioned@Kryptoblog as a possible contact on low power crypto. -
@blaufish_@bascule More seriously. Encrypt-then-MAC. For low power, embedded SipHash might be an suitable MAC. https://131002.net/siphash/#in
