This module can provide common hashing functions. They can be used for verifying integrity of data. They also allow for more secure storage of passwords, making it harder for attackers who break in and obtain data to retrieve the original plaintext.
Warning: Some of these algorithms including md5 and sha1 are considered cryptographically insecure due to collisions.
Using these hashes directly without a salt also carries the risk of rainbow table attacks. The best practices for password hashing change over time and it's best to do your own research. As of writing, I would recommend using the external bcrypt package for passwords over these functions.
