Hash
SHA-1, SHA-256, SHA-512
Frequently Asked Questions
What is a hash function?
A hash function converts input data of any size into a fixed-size string of characters. The same input always produces the same hash.
Which hash algorithm should I use?
For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are considered weak and should only be used for checksums, not security.
Can I reverse a hash?
No, hash functions are one-way. You cannot recover the original data from a hash. This is why they are used for password storage.
