Which hashing algorithm is best for uniqueness and speed? - Software Engineering Stack Exchange
I tested some different algorithms, measuring speed and number of collisions.

I used three different key sets:

A list of 216,553 English words (in lowercase)
The numbers "1" to "216553" (think ZIP codes, and how a poor hash took down msn.com)
216,553 "random" (i.e. type 4 uuid) GUIDs

For each corpus, the number of collisions and the average time spent hashing was recorded.

I tested:

DJB2
DJB2a (variant using xor rather than )
FNV-1 (32-bit)
FNV-1a (32-bit)
SDBM
CRC32
Murmur2 (32-bit)

SHA-1 collision attacks are now actually practical and a looming danger | ZDNet
should switch to (in order of preference):

* BLAKE2b / BLAKE2s
* SHA-512/256
* SHA3-256
* SHA-384
* Any other SHA2-family hash function as a last resort

"...unless they're storing passwords! In which case, they should switch to (in order of preference):

* Argon2id with memory >= 32MiB, >= 2 rounds, and >= 2 parallelism
* scrypt / yescrypt with memory >= 32 MiB, >= 4 rounds, and >= 1 parellelism
* bcrypt (for PHP devs, password_hash() and password_verify() does the trick)
* PBKDF2-SHA512 with 85,000 iterations as a last resort

Check and verify md5/sha1/sha256 checksums for MacOS X when I download files - nixCraft | https://www.cyberciti.biz/
The solution is to check `uname -s` == "Darwin" and use `shasum -a 1` instead of `sha1sum`, which only exists on Linux
