Most reliable hashing method?

Question

Data protection

Please tell me the most reliable hashing method from the list
And its implementation in C ++ (Qt)

Answer 1

the most reliable - the most unpopular

Answer 2

The most reliable so far is probably sha-2, after all, the default standard now is hashes from this family.

Answer 3

I do it twice by md5, and write the hash back to front in the database

Answer 4

The most reliable for what exactly, i.e. at what plan? Reducing the likelihood of collisions or what?

Answer 5

Sha 2 and Whirpool are strong.
Personally, I recommend something like this:

salt_hash = hash('sha256', salt_str);
hashing_string = salt_hash .secret_password;
pwd_hash = hash('whirlpool', hashing_String);

Answer 6

The most reliable in the current realities is the one that is the slowest.

"SHA-512(unix) aka butthurt algorithm.
Would be useful for benchmarking, as it's the slowest algo on the planet."
