Question 1

What is a hash generator for?

Accepted Answer

Hashes such as SHA-256 turn any text into a fixed-length string. They are used to check data integrity and to compare content quickly.

Question 2

Can a hash be reversed to the original?

Accepted Answer

No. Hash functions are one-way. You cannot recover the input from the hash, only compare the hashes of two values.

Question 3

Which algorithm should I choose?

Accepted Answer

For integrity and general use pick SHA-256. Avoid the older MD5 and SHA-1 for security purposes, as they are considered weak.
