MD5 Hash

Compute an MD5 hash of text in hex or Base64 for legacy systems, checksum verification, and compatibility testing.

For this tool, processing runs locally in your browser and data is not sent to the server.

MD5 Hash is a free online tool that computes an MD5 hash from any text. Output is available in hex or Base64, and can be compared against an expected value. The tool is useful for legacy systems, old integrations, checksums, test data, and compatibility checks. The tool runs in your browser and does not send data to the server. Note: MD5 is cryptographically broken and must not be used for passwords, tokens, digital signatures, or new security scenarios.

How to use

Paste a string, text, legacy payload, or test value into the input field.
Choose an output format: Hex or Base64.
Get the MD5 hash and optionally compare it against an expected value.
Copy the result for legacy systems, checksums, tests, logs, or compatibility with older software.

More about this tool

MD5 Hash computes an MD5 hash from a string or text. The tool is useful for legacy systems, old integrations, checksums, test data, logs, and verifying compatibility with older software. The result can be output as Hex or Base64 and compared against an expected MD5 value.

MD5 is considered cryptographically broken and must not be used for passwords, tokens, digital signatures, data protection, or any new security scenario.

All processing is done locally in the browser. Your data is not sent to the server.

Frequently Asked Questions

What is MD5?

MD5 is an older hash function that transforms input data into a short hash. MD5 is now considered cryptographically broken for security purposes.

Can MD5 be used for passwords?

No. MD5 must not be used for storing passwords. Use purpose-built algorithms with salt and work factors such as Argon2, bcrypt, or scrypt.

Can MD5 be used for API signatures?

For new API signatures, MD5 should not be used. HMAC-SHA256 or other modern schemes with a secret key are the standard choice.

When is MD5 still useful?

MD5 can be needed for compatibility with legacy systems, old integrations, test examples, and simple checksum scenarios where security is not a concern.

How is MD5 different from SHA-256?

SHA-256 is modern and significantly more resistant to attacks. For new checksum tasks, use SHA-256 unless MD5 compatibility is required.

Can I verify whether an MD5 matches?

Yes. Enable hash comparison, paste an expected value, and the tool will show whether it matches the computed MD5.

Can MD5 be reversed?

No. MD5 is a hash function, not encryption. The original text cannot be directly recovered from the hash.

Can I compute the MD5 hash of a file?

This tool is designed for text. For files, a separate file checksum tool where you can select a file and compute its hash locally is more appropriate.

Is my data sent to the server?

No. Text is processed locally in the browser and is not sent to the server.

Do I need to register?

No. The tool works immediately without registration.
