Hash Generator (MD5 / SHA-1 / SHA-256 / SHA-512)

Paste any text to instantly generate its MD5, SHA-1, SHA-256, and SHA-512 hashes, and optionally compare two hashes.

Generate multiple hashes from one input

Paste any text and we'll calculate its MD5, SHA-1, SHA-256, and SHA-512 hashes. Great for quick checksum lookups and debugging.

Security note: MD5 and SHA-1 are considered weak for password storage. Use this tool for checksums and experiments, not as a replacement for proper password hashing.

Input text

Enter the text you want to hash. Hash results update automatically.

Hash results

Hashes will appear here once you start typing in the input above.

About these hash functions

Hash functions turn any text into a fixed-length fingerprint. They are commonly used for file integrity checks, API signatures, and verifying that data has not changed.

Important: MD5 and SHA-1 are considered cryptographically broken and should not be used to protect passwords or other sensitive secrets. Prefer SHA-256 or stronger algorithms together with slow, password-specific hashing (bcrypt, Argon2, PBKDF2) on the server side.

This tool is meant for quick lookups and debugging. Do not paste high-value secrets into shared or untrusted devices.

Compare two hashes (optional)

Paste any two hash strings below to quickly check whether they are exactly the same. This is helpful when verifying files or responses.

Instant File Integrity

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes instantly in your browser. Perfect for verifying file downloads or API payloads.

Instant Results

Hashes are calculated in real-time as you type, with zero latency.

Multi-Algo

Get MD5, SHA-1, SHA-256, and SHA-512 outputs simultaneously.

Privacy First

Your data is processed locally using the Web Crypto API.

Comparison

Built-in tool to compare two hashes and check for exact matches.

How this Hash Generator (MD5 / SHA-1 / SHA-256 / SHA-512) works

This cryptographic utility generates hash digests from input text using algorithms like MD5, SHA-1, SHA-256, SHA-512, or bcrypt, producing fixed-length fingerprints useful for data integrity verification, password storage, or file comparison. Users input plaintext and select hashing algorithms, receiving hexadecimal or base64-encoded outputs instantly. The tool supports multiple simultaneous hashing displaying all algorithm results concurrently, case-sensitive/insensitive options, and custom salt addition for enhanced security. Common applications include generating password hashes for database storage, verifying file integrity through checksum comparison, creating unique identifiers for data deduplication, or demonstrating hash function properties in cryptographic education. Advanced features support HMAC generation for message authentication, configurable iteration counts for key derivation functions, and side-by-side comparison highlighting differences between hash outputs, all processing client-side ensuring sensitive data never leaves the browser.

How to Use

1

Paste or type text

Enter any string you want to hash — for example a token, file checksum, or API payload.

2

Review the hashes

We calculate MD5, SHA-1, SHA-256, and SHA-512 digests and show them in hex format.

3

Optionally compare hashes

Use the comparison section to check whether two hash strings are identical.

Example Usage

Paste any text and instantly see the corresponding MD5, SHA-1, SHA-256, and SHA-512 hashes.

Input

Frequently Asked Questions

What does a Hash Generator do?
A hash generator creates a fixed-length hash from your input text using algorithms like MD5, SHA-1, SHA-256, or SHA-512. Developers use hashes for integrity checks, fingerprints, and verifying data hasn't changed.
Is hashing the same as encryption?
No. Hashing is one-way, meaning you cannot convert the hash back into the original text. Encryption is reversible with a key, so use encryption when you need to decrypt later.
Which hash algorithm should I use?
For modern integrity and security use cases, SHA-256 or SHA-512 is a safer choice. MD5 and SHA-1 are considered weak for security-sensitive tasks, though they can still be used for non-security checksums in some workflows.
Why do two slightly different inputs create totally different hashes?
That's a core property of hashing called the avalanche effect. Small input changes produce a very different output, which helps detect tampering or accidental edits.
Is this Hash Generator secure?
Yes. This tool runs 100% client-side, so your input is hashed in your browser and never uploaded to a server.
