Hash Generator (MD5, SHA-1, SHA-256)

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes with optional salting, multi-algorithm output, hex/Base64 formatting, and detailed metadata — all client-side.

How It Works

📝

Enter Text or Drop Files

Paste plain text, JSON payloads, or drag-and-drop file contents to hash. The tool supports Unicode input and updates automatically as you type or upload.

⚙️

Choose Algorithms & Salt

Select one or many algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512), add an optional salt prefix, and pick hex or Base64 output formatting for each digest.

⚡

Generate Hashes Instantly

Hashes are produced locally using the Web Crypto API (plus an MD5 implementation) with no network requests. Toggle uppercase output and include digest lengths when needed.

📤

Export & Share Results

Copy hashes, download CSV/text exports, or revisit past calculations through tool history to document integrity checks for QA, releases, or security reviews.

Problems It Solves

🧮

Problem

Manual hash calculations across multiple algorithms slow down release checklists and increase the risk of transcription mistakes.

Solution

Generate several digests in one click with synchronized outputs so QA teams and DevOps engineers can compare MD5, SHA-1, and SHA-256 values side by side.

🔏

Problem

Security audits require salted hashes and consistent output formatting, but ad-hoc scripts often produce uneven results.

Solution

Apply optional salt prefixes, enforce uppercase hex, include length metadata, and share reproducible output for compliance documentation.

🛡️

Problem

Teams need a trusted, offline tool to verify downloads or troubleshoot cache keys without leaking sensitive data.

Solution

All hashing runs in-browser with no telemetry, enabling safe checksum verification of deployment artifacts, API responses, or customer files.

Why Choose This Tool

🔒

On-Device Security

Hashes never leave your machine. Ideal for confidential payloads, production credentials, and compliance workflows that forbid remote tooling.

🛠️

Power for Professionals

Support for multi-algorithm output, salts, uppercase hex, and digest lengths mirrors the needs of SRE, DevOps, and security engineers.

📊

Actionable Metadata

Each run includes algorithm names, output lengths, and configuration snapshots so you can paste results into tickets or audit logs with confidence.

⚙️

Streamlined UX

Auto-processing, keyboard shortcuts, copy/download buttons, and history make repeat hashing tasks fast during investigations or build pipelines.

Frequently Asked Questions

Which hash algorithm should I use?
For new applications, use SHA-256 or higher. MD5 and SHA-1 are deprecated for security use but still useful for checksums and non-cryptographic purposes.
Is MD5 secure for passwords?
No, MD5 is cryptographically broken and should never be used for passwords. Use bcrypt, scrypt, or Argon2 for password hashing instead.
What's the difference between hex and Base64 output?
Hex uses 0-9 and A-F characters (longer), while Base64 uses A-Z, a-z, 0-9, +, / (shorter). Both represent the same hash data in different formats.
Can I reverse a hash to get the original data?
No, cryptographic hashes are one-way functions. You cannot reverse them to get the original data, but you can verify if input matches by comparing hashes.
Why do I get different hashes for the same text?
Make sure you're using the same algorithm and text encoding. Different algorithms or character encodings will produce different hashes.
