Cryptography is an essential element in OpenBSD's proactive security model, figuring most prominently in their use of secure ciphers for encrypting the password database, still years ahead of other project's weak and obsolete methods. Strong encryption can be included because Canada, where the project is based does not restrict export of encryption algorithms or software (this why they say "Because we can!" for reasons why they include cryptographic software in OpenBSD).

OpenBSD includes:

  1. IPSec
  2. LibreSSL
  3. /dev/(u)random
  4. MD5 and DES libcrypt functions

These components make up the strong encryption methods in OpenBSD.
