Frequently Asked Questions
What is a cryptographic hash function?
A cryptographic hash function takes input data of any size and produces a fixed-size output (the hash or digest). It is a one-way function — you cannot reverse a hash to recover the original input. The same input always produces the same hash, but even a single character change produces a completely different output (the avalanche effect). Use our free hash generator to compute hashes for any text.
Which hash algorithm should I use?
SHA-256: Recommended for most purposes — digital signatures, file integrity, password hashing (with salt), blockchain - SHA-512: Use when you need a 512-bit output, typically for high-security applications - SHA-1: Deprecated. Do not use for security purposes - MD5: Cryptographically broken. Only use for non-security checksums and legacy compatibility Our hash generator supports all five algorithms in one interface.
