Generate Hashes Instantly with Convert-Text.net
Welcome to Convert-Text.net's Hash Generator, the fastest way to turn any text into its MD5, SHA-1, SHA-256, or SHA-512 digest. Paste a message, password check, API payload, or file checksum string into the box above, and every selected algorithm updates its result in real time as you type.
No sign-ups, no uploads, and no limits. Every hash is computed locally inside your browser using the Web Crypto API, so your data never leaves your device.
Common Uses for Generating a Hash
- Verify Downloads: Compare a downloaded file's MD5 or SHA-256 checksum against the one published by the author.
- Check Data Integrity: Confirm that a string or payload was not modified in transit by comparing its hash.
- Deduplicate Records: Hash emails, user names, or IDs to spot duplicates without exposing the raw values.
- Store Password Placeholders: Hash a value before saving it to demo how digests work (always use bcrypt, Argon2, or PBKDF2 for real password storage).
The Hash Algorithms We Support
MD5 produces a fast 128-bit digest (32 hex characters). It is no longer considered collision-safe, but remains pervasive in checksums and legacy systems. SHA-1 produces a 160-bit digest (40 hex characters) and is also deprecated for security-critical work. SHA-256 produces a 256-bit digest (64 hex characters) and is the current industry standard used in TLS, certificates, and blockchains. SHA-512 produces a 512-bit digest (128 hex characters) and offers the largest output of the group for maximum-length integrity keys.
How to Generate a Hash in 3 Steps
- Paste Your Text: Type or paste any text, code, or data into the input box.
- Tick the Algorithms: Choose MD5, SHA-1, SHA-256, and/or SHA-512 from the checkboxes above the editor.
- Copy the Hash: Each result row has its own Copy button so you can grab exactly the digest you need.
100% Client-Side Privacy & Security
Your text never leaves your browser. Convert-Text.net computes all hashes locally with the browser's built-in Web Crypto API and a lightweight pure-JavaScript MD5 implementation. Nothing you paste is uploaded, logged, or stored — making this tool safe for API secrets, private documents, and sensitive data.
Frequently Asked Questions
What is a hash and what does this tool do?
A hash is a fixed-length hexadecimal string produced by a one-way calculation over your input. This tool runs your text through the selected algorithms and displays every resulting digest in real time.
Why is SHA-256 better than MD5?
SHA-256 produces a longer 256-bit digest and is resistant to known collision attacks that make MD5 unsuitable for security-critical use. For password hashing, however, you should use functions designed for that purpose, such as bcrypt or Argon2, regardless of the digest choice.
Can I decrypt or reverse a hash back to my text?
No. Hashing is a one-way function, so a digest cannot be reversed. The only way to recover the original value is to guess it and compare hashes, which is why strong, unique passwords matter.
Is the Hash Generator free and private?
Yes. Convert-Text.net is 100% free and runs entirely client-side. Your input text is processed in your browser and never transmitted, saved, or logged on any server.
How long are the checksum values?
MD5 is 32 characters, SHA-1 is 40, SHA-256 is 64, and SHA-512 is 128 characters — regardless of how long your input text is.
