For example, to use a HMAC-SHA-1 based PBKDF2 key derivation function, you can get a derived key for e.g. AES-256 (which needs a 32-byte key) by doing:

dk := pbkdf2.Key([]byte("some password"), salt, 4096, 32, sha1.New)

Remember to get a good random salt. At least 8 bytes is recommended by the RFC.

Using a higher iteration count will increase the cost of an exhaustive search but will also make derivation proportionally slower.
