About Hash & Crypto Tools

MD5, SHA-256, HMAC, bcrypt and other cryptographic utilities

Cryptographic hashes turn any input — a password, a file, a string — into a fixed-length fingerprint that is practically impossible to reverse. They power password storage, file-integrity checks, digital signatures, blockchains and cache busting. ToolsRift hosts 25+ hash and crypto tools so you can generate, compare and verify hashes for almost any common algorithm without leaving your browser.

You can generate MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3 family hashes, HMAC variants with custom secrets, bcrypt hashes with adjustable cost factors, and UUIDs in v1, v4 and v7 flavors. There are also helper tools — file checksum verifier, hash comparator, salt generator, secure password generator and more.

Every algorithm is implemented using the browser's Web Crypto API where available, with audited JavaScript fallbacks for older algorithms. Outputs match exactly what you would get from openssl, sha256sum or Node's crypto module.

Why ToolsRift

Why our hash & crypto tools are different

Hashing sensitive inputs on a remote site is a bad habit. If you paste a real password into a server-side MD5 generator, that password is now in someone's access logs. ToolsRift runs every hash computation in your browser — even bcrypt, which we run via WASM. Your input never leaves your device, and you can confirm this by disabling network access after loading the page.

Each tool also includes the relevant context: which algorithms are considered cryptographically broken (MD5, SHA-1), which are still safe for non-security uses like content addressing, what salt and cost mean for bcrypt, and when to choose HMAC over a plain hash. That makes the tools useful for learning as well as everyday work.

How It Works

How to use hash & crypto tools

1
Pick the algorithm
Open the hash tools dashboard and choose the algorithm you need. If you are not sure, SHA-256 is the right default for most modern use cases.
2
Paste your input
Type or paste text into the input box, or drop a file onto the dropzone to hash file contents. For HMAC, enter the secret key as well.
3
Compare to expected value
For verification tasks, paste an expected hash into the comparator. The tool will highlight character-level differences so you can spot tampering or corruption immediately.
4
Copy the hex digest
Output is shown as a lowercase hex string by default. Toggle to uppercase or Base64 if needed, then copy with one click.

FAQ

Frequently Asked Questions

Answers to common questions about our hash & crypto tools.

Is it safe to hash passwords here?+
Yes — all hashing runs locally in your browser, nothing is sent to a server. That said, never store user passwords as plain MD5 or SHA-256 in production. Use bcrypt, scrypt, or Argon2 with a unique per-user salt. This tool supports bcrypt with adjustable cost factors for exactly that reason.
Are MD5 and SHA-1 still useful?+
They are cryptographically broken for security uses like password storage or digital signatures. They are still fine for non-security uses: file content addressing, cache keys, ETag generation, or quick integrity checks where you only care about accidental corruption, not deliberate attacks.
What does the bcrypt "cost" parameter do?+
Cost controls how slow the hash is. Each step up doubles the time. Higher cost = harder to brute-force, but slower for legitimate logins. Cost 10-12 is typical for web apps; cost 14 is appropriate for high-value accounts. ToolsRift defaults to a sensible value.
Can I hash a large file?+
Yes — file hashing streams the file through the hash function in chunks, so even multi-gigabyte files work without loading everything into memory. The hash digest appears once the full file has been read.
Why do two tools give different hashes for the same input?+
Almost always a character-encoding or whitespace issue: a trailing newline, a Windows CRLF vs Unix LF, or a hidden BOM. Hashes are exact — even one byte of difference produces a completely different output. Strip whitespace and re-hash to check.
