Hash Generator (MD5 / SHA)
Generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from text.
—————Computed in your browser — nothing is sent.
About this tool
The Hash Generator (SHA) computes a hash of your text using the SHA family of algorithms — SHA-1, SHA-256, SHA-384, and SHA-512. Type your text and the hexadecimal hash appears immediately. It is ideal for developers who need a quick sha checksum to verify the integrity of data or files.
The key thing to understand is that a hash is a one-way function. Once text is turned into a hash there is no way to reverse it back into the original — a hash is not reversible encryption. That is precisely why it is used to detect whether data has been altered, rather than to hide information you intend to read again later.
A sha256 generator is useful in many situations:
- Verifying that a downloaded file's checksum matches the original
- Checking whether two pieces of text are identical without reading both in full
- Producing a stable fingerprint for the same data every time
On algorithm choice, SHA-256 is the standard, secure, and most popular option today, while SHA-1 is considered outdated and should no longer be used for security purposes. This generate hash tool runs entirely in your browser, so the text you enter never leaves your device — you can use it confidently with sensitive data. It is free, requires no account, and stores nothing.
How to use
- 1Type or paste the text you want to hash into the input field
- 2All five digests — MD5, SHA-1, SHA-256, SHA-384 and SHA-512 — are computed at once
- 3The hash is computed instantly and shown in hexadecimal
- 4Click to copy the hash for comparison or to store as a checksum
Frequently asked questions
- Can I decrypt a hash back into the original text?
- No. SHA is a one-way function, so a hash cannot be reversed into the original input. That is why it suits integrity checking rather than storing data you need to read back.
- Which SHA variant should I choose?
- SHA-256 is the most widely used standard and is secure enough for general work. SHA-1 is considered weak and should only be used to verify legacy checksums, never for security.
- Does this tool send my text anywhere?
- No. The hash is computed entirely in your browser and the text is never sent to a server, so it is safe even for sensitive input.
- Why does the same text always produce the same hash?
- Hashing is deterministic — the same input with the same algorithm always yields the same value, which is exactly what lets you detect whether data has changed.
- Is it free, and do I need an account?
- It is completely free with no signup, and none of your data is stored.
