How to use
1. Enter or paste the text you want to generate a hash for in the input box above.
2. Click the Generate button to create the hash result.
Options
1. Process each line separately: When enabled, each line of input is processed separately, and each line produces its own hash. When disabled, the entire input is processed as one single text value.
2. Ignore blank lines: When enabled, blank lines are skipped and no results are generated for them. This option is usually most useful when processing text line by line.
3. Uppercase result: When enabled, the generated hash is displayed in uppercase letters, for example A-F instead of a-f. The original input text is not changed.
Example
Enter the following content:
123456

About This MD5 Hash Generator
StarryTool's MD5 hash generator creates a 32-character MD5 digest from the text you enter. It is useful for quick text hashing, test data, basic comparisons, debugging, and older systems that still require MD5 values.
This page is for text input. You can paste a string, sentence, code snippet, ID, or sample content and generate its MD5 hash directly in your browser.
MD5, short for Message-Digest Algorithm 5, produces a 128-bit hash value that is usually shown as a 32-character hexadecimal string. The same input produces the same MD5 hash, while even a small change in the input usually creates a very different result.
• What This Tool Is Good For
Text Hashing: Generate an MD5 hash from plain text, strings, code snippets, IDs, or sample input.
Testing and Debugging: Create predictable MD5 values for scripts, examples, logs, database tests, and development workflows.
Basic Comparisons: Compare MD5 results from non-sensitive text when both sides use the same input and encoding.
Legacy Compatibility: Produce MD5 digests for older software, APIs, databases, or tools that still expect a 32-character MD5 value.
• Important MD5 Security Notes
MD5 is fast and widely supported, but it is no longer suitable for security-sensitive cryptographic use because practical collision attacks exist.
Do not use MD5 for password storage, digital signatures, certificates, or any workflow that requires strong security guarantees.
For password storage, use a modern password hashing method such as Argon2id, bcrypt, scrypt, or PBKDF2 with a unique salt and an appropriate work factor.
For stronger general-purpose hashing, use SHA-256 or SHA-512 unless your system specifically requires MD5.
• Features
Text to MD5: Paste or type text and generate its MD5 digest online.
Fixed Output Length: MD5 returns a 128-bit digest, commonly displayed as a 32-character hexadecimal value.
Consistent Results: The same text input produces the same MD5 hash, which helps with repeatable testing and comparison.
Line-by-Line Processing: Generate separate MD5 results for multiple non-empty lines when this option is enabled.
One-Way Hashing: MD5 creates a digest from text; it does not decrypt back to the original input.
• Common Uses
Create an MD5 hash from a string or block of text.
Generate test hashes for sample data, logs, scripts, or documentation.
Compare non-sensitive text values when both sides use MD5.
Match older APIs, databases, or tools that expect MD5 digests.
