Frequently asked questions

What is SHA3-384 Hash Generator?

Generate a SHA3-384 hash of any text instantly in your browser, with hex or Base64 output. Keccak sponge, 384-bit.

When would I actually use this?

Verifying a download matches its published checksum, comparing two files without reading them, and generating a signature for an API request.

What is the most common mistake?

Hashing a password with a fast algorithm. MD5 and SHA are built to be quick, which is exactly wrong for passwords — those need a deliberately slow function like bcrypt, scrypt or Argon2.

How is SHA3-384 Hash Generator different from SHA3-256 Hash Generator?

They sit next to each other but answer different questions: SHA3-256 Hash Generator is the one to open when you need it to generate a SHA3-256 hash of any text instantly in your browser, with hex or Base64 output. Keccak sponge, FIPS 202. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

SHA3-512 Hash Generator is the closest one after this: Generate a SHA3-512 hash of any text instantly in your browser, with hex or Base64 output. Keccak sponge, 512-bit.

What else is worth having open alongside it?

FNV-1a Hash Generator and MD5 Hash Generator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

The digests follow their published specifications and are computed by the browser's own crypto implementation where one exists, so a value can be checked against any other conforming tool.

ComparisonMD5, SHA-1, SHA-256: Which Hash, and For WhatMD5 is broken and MD5 is fine, depending on which of three security properties you needed. Here is what collision resistance, second-preimage resistance and preimage resistance actually mean, which algorithm still has which, and why none of them belongs near a password.ComparisonChecksums Are Not Hashes: CRC-32, Adler-32 and What They Are ForA checksum catches accidents. A cryptographic hash resists an attacker. A hash-table hash spreads keys. Three different jobs, three different families — and here is a CRC-32 collision constructed by hand in 0.11 seconds to show exactly why you cannot substitute one for another.ExplainerPassword Entropy: What a Strength Meter Cannot KnowEntropy measures the process that produced a password, not the characters in it. H = L x log2(R) is only true when every character was chosen at random — which is exactly why a meter scoring a human-invented password on its character classes is measuring the wrong thing.ExplainerWhat Is Inside a JWT — and What It Does Not ProtectA JWT is signed, not encrypted. Anyone holding the token can decode the payload and read every claim in it. Here is a real token, decoded without any key, plus the three attacks the signature is supposed to stop and the one problem it cannot solve.ExplainerWhat Is a Hash Function? (MD5, SHA-256)A hash function turns any input into a fixed-size fingerprint. Here's what it does, its key properties, common uses, and which algorithms are safe.GuideEncrypt a File, Then Send the Key Down a Different RoadThe encryption is the easy half. Here is exactly what the browser tool does to your file — cipher, key derivation, salt, nonce — and why an encrypted attachment with the passphrase in the same thread protects nothing at all.
