You can use the golang.org/x/crypto/sha3 [docs] package to perform SHA-3 encoding on a string. We have an example function below, it will take your string and write it as a hash. Then convert that binary back into a hexadecimal string using Sprintf.

Advantages of Using SHA3

Security: SHA-3 was designed to provide higher security compared to SHA-2 by using a different construction called “sponge construction”, which makes it more resistant to various types of attacks, such as collision and preimage attacks.

You can use the crypto/md5 [docs] package in Go to perform MD5 encoding on a string. We have an example function below, it will take your string and write it as a hash. Then convert that binary back into a hexadecimal string using Sprintf.

Note: There are more modern approaches than md5 these days - and it isn’t recommended for many things, but definitely not password hashing.

Here’s an example of how to use it:
