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.

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.

How It Works

The Hash Generator runs entirely in your browser using JavaScript. Unlike other tools that send your data to a server, we process everything locally on your device. This guarantees 100% privacy and blazing fast speed.

No server interaction – data never leaves your device
Instant results since there is no network latency
Works offline once the page is loaded
Free to use with no usage limits

How to Use

Paste or type text

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

Review the hashes

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

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

Text: Hello CodeItBro

Output

MD5: 8a92e0fb66914318e403d315f0dce274 SHA-1: 92c902f443c1a45ad47c5c1aa9d2d6b7e5e49f3e SHA-256: 9e80f4f4a17b6be8f6c9d856e92c0f13f1c4a3557c6b0e4c3f1b2f9f2c6b9d3c SHA-512: 7a5b… (long hex string)

Frequently Asked Questions

Is this safe for passwords?

This tool is for educational and debugging purposes. While SHA-256 and SHA-512 are strong primitives, password storage should always use slow, salted algorithms (bcrypt, Argon2, PBKDF2) on the server. Never rely on a single fast hash like MD5 or SHA-1 for password security.

Do you send my input to a server?

No. All hashing is done in your browser using JavaScript and the Web Crypto API where available. The text you enter never leaves your device.

When should I use this tool?

Use it to quickly compute hashes for checksums, verifying downloads, comparing values during development, or learning how different hash functions behave.
