Updated Apr 5 2019:

because this is a gist from 2011 that people stumble into and maybe you should AES instead of 3DES in the year of our lord 2019.

some other notes:

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

// Params:
// 1. query (filter) if you only want to remove this field from some records. {} will select any.
// 2. $unset the field(s) that you want to remove. Here I've set them to null but the value doesn't matter as it's ignored.
// 3. multi must be set to true otherwise it will only operate on the first record that it finds.
// 
// Run this command in the MongoDB shell
