About Hash Generator
Paste or type any text and this tool instantly computes its MD5, SHA-1, SHA-256, and SHA-512 hashes at the same time, each shown as lowercase hexadecimal in its own row with a one-click Copy button. Every digest recomputes automatically as you edit, so whether you need a quick MD5, a SHA-256 fingerprint, or a full SHA-512 value, the fresh result is always on screen without pressing a button.
Input is encoded as UTF-8 before hashing, so accented letters, symbols, and emoji produce correct, standards-compliant digests, and the tool shows both the character count and the UTF-8 byte count next to your text. Use the output to verify a published checksum, build a cache key, compare two blocks of text, or generate a fixed-length fingerprint from any string. MD5 and SHA-1 are handy for non-security checks like file integrity, while SHA-256 and SHA-512 are the ones to reach for when you actually care about collision resistance.
The whole thing is free with no sign-up and no usage limits. SHA-1, SHA-256, and SHA-512 are calculated with your browser's built-in Web Crypto API and MD5 runs through an inline JavaScript routine, so everything happens on your device — your text is never uploaded, stored, or logged anywhere.
Frequently asked questions
- Is this hash generator free to use?
- Yes, it is 100% free with no account, sign-up, or usage limits. Generate as many hashes as you like.
- How do I generate an MD5 hash of my text?
- Just paste or type your text into the box and the MD5 hash appears instantly in the first row as 32 lowercase hex characters. There is no button to press; it updates as you type, and you can copy it with a single click.
- Can it create SHA-256, SHA-1, and SHA-512 hashes too?
- Yes. Every time you enter text it produces MD5, SHA-1, SHA-256, and SHA-512 side by side, so you get all four at once. SHA-1 is 40 hex characters, SHA-256 is 64, and SHA-512 is 128, each in its own row with its own Copy button.
- Is my text or data uploaded to a server?
- No. All hashing happens locally in your browser. SHA-1, SHA-256, and SHA-512 use your browser's native Web Crypto API, and MD5 runs through an inline JavaScript routine, so nothing you type is ever sent, stored, or logged anywhere.
- Which hash algorithms does it support?
- It generates four hashes at once: MD5 (128-bit), SHA-1 (160-bit), SHA-256 (256-bit), and SHA-512 (512-bit), each shown in hexadecimal.
- How is the text encoded before hashing?
- Your input is encoded as UTF-8 bytes before hashing, so accented characters, symbols, and emoji all produce correct, standards-compliant digests. The tool also shows the UTF-8 byte count next to the character count.
- Should I use MD5 or SHA-1 for security?
- No. MD5 and SHA-1 are considered cryptographically broken and are unsafe for passwords, signatures, or security. Use them only for checksums, cache keys, or comparing files. For security-sensitive work, prefer SHA-256 or SHA-512.
- Can I use this as a password hash generator?
- You can hash a password string to SHA-256 or SHA-512 here, but this is not meant for storing account passwords. Secure password storage needs a slow, salted algorithm like bcrypt or Argon2, which this tool does not perform. Treat these digests as fingerprints, not as a password store.
- Does this generate NTLM hashes?
- No. This tool covers MD5, SHA-1, SHA-256, and SHA-512 only and does not produce NTLM hashes. If you specifically need an NTLM value, you will need a dedicated NTLM tool.
- Can it produce bcrypt hashes?
- No. bcrypt uses a random salt and an adjustable work factor, so its output is not a plain digest of your text, and this tool does not generate it. It is built for the fixed-output MD5 and SHA family digests instead.
- Can I use it as a random hash generator?
- There is no built-in randomizer, but you can paste any random or throwaway text and copy its SHA-256 or MD5 digest to get a random-looking, fixed-length hex string. Change a single character and the entire hash changes completely.
- Can I turn a hash into a color code?
- Yes, in a simple way: hash any text, then take the first six hex characters of the digest and add a # in front to get a repeatable color code like #a1b2c3. The same input always maps to the same color, which is handy for coloring avatars or tags.
- Can I use these hashes to verify a file checksum?
- Yes. Paste the text and compare the generated MD5 or SHA-256 value against a published checksum to confirm the content matches. Note that this tool hashes text input rather than uploaded binary files.
