Frequently Asked Questions
What is a hash function?
A hash function takes input data of any size and produces a fixed-size output (the hash or digest). The same input always produces the same hash, but even a tiny change in input produces a completely different hash.
Which hash algorithm should I use?
For file integrity checks, SHA-256 is the standard choice. MD5 and SHA-1 are considered cryptographically broken and should not be used for security purposes, but they are still useful for checksums and non-security applications.
Can a hash be reversed?
No. Cryptographic hash functions are one-way — you cannot recover the original input from a hash. Attackers use precomputed tables (rainbow tables) or brute force, which is why strong, unique inputs matter.
What is the difference between hashing and encryption?
Hashing is a one-way process — you cannot recover the original data. Encryption is two-way — data can be encrypted and then decrypted with the correct key. Hashing is used for verification; encryption is used for confidentiality.
