About MD5 Hash Generator
MD5 (Message-Digest 5) is a widely used hash function. It has been used in a variety of security applications and is also commonly used to check the integrity of files. However, MD5 is not collision resistant and it isn't suitable for applications like SSL/TLS certificates or digital signatures that rely on this property.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: text.
Format reference: MD5 background and specification
Example
Use “Try example” to load this public sample and its settings, then run it.
Input
Hello, world!
Result

Use MD5 for legacy compatibility
MD5 has practical collision attacks and is unsuitable for new security-sensitive designs, signatures or password storage. Use this tool when a legacy format or published checksum specifically requires MD5.
Parameters
This tool does not need additional parameters.
Before interpreting the result
Use a checksum to compare exact bytes against a trusted digest. Choose a password hashing function for passwords and a MAC for keyed authentication. MD5 and SHA-1 are unsuitable for new security-sensitive designs.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
