FAQ
What is a hash function?
A hash function takes input data of any size and produces a fixed-size string of characters. The output (hash) is unique to the input - even a tiny change produces a completely different hash.
Are hash functions reversible?
No, cryptographic hash functions are one-way operations. You cannot reconstruct the original input from its hash. This property makes them essential for password storage and data integrity verification.
Which hash algorithm should I use?
For security purposes, SHA-256 or SHA-512 are recommended. MD5 and SHA-1 are considered broken for cryptographic use but are still useful for checksums and non-security applications.
