Frequently Asked Questions
What is a hash?
A hash is a fixed-size string generated from input data. The same input always produces the same hash.
Which hash algorithm should I use?
For security, use SHA-256 or SHA-512. MD5 and SHA-1 are outdated and not recommended for security purposes.
Can hashes be reversed?
No, hashes are one-way functions. You cannot reverse a hash to get the original data.
