Hash Generator

If you've ever needed to check whether a downloaded file was tampered with, or you're building a system that needs to verify data integrity without storing the actual data, you need a hash function. A hash takes any input—a password, a file, a sentence—and turns it into a fixed-length string of characters. Change one letter in the input and the entire output changes. That's the whole point. It's a one-way fingerprint. Paste your text in, pick your algorithm, and the digest generates instantly in your browser. Nothing you type here gets sent anywhere.

MD5 and SHA-1

MD5 is fast and still fine for checksums, like confirming a file downloaded correctly. But it's broken for anything security-related. Researchers have been able to create two different files with the same MD5 hash since 2004, which means it can't be trusted to prove authenticity. SHA-1 has the same problem; Google demonstrated a practical collision attack against it back in 2017, and browsers stopped trusting SHA-1 certificates years ago.

SHA-256

SHA-256 is where most modern systems land. It's part of the SHA-2 family, it's what Bitcoin uses for mining and transaction verification, and no practical collision attack exists against it. If you're hashing passwords before storage (though you should really be using bcrypt for that), verifying API payloads, or generating unique IDs from content, SHA-256 is the safe default.

SHA-384, SHA-512, and SHA-3

SHA-384 and SHA-512 are the longer siblings in the same family, offering more output bits for applications that need extra collision resistance, often in high-security government or financial contexts. SHA-3 is the newest standard, built on a completely different internal structure (Keccak) than SHA-2, and it exists partly as a hedge in case a future weakness is ever found in SHA-2.

Hashing is not encryption

One thing worth knowing: hashing is not encryption. You can't reverse a hash back into the original input. If you need to get the original data back later, you want encryption, not hashing. If you're checking whether two things match, hashing is exactly right, since you just hash both and compare the output strings instead of storing the sensitive original.

How it works

Three steps, no setup

Enter your text

Type or paste the string, password, or file content you want to fingerprint.

Pick an algorithm

Switch between MD5, SHA-1, SHA-2 and SHA-3 variants to compare output lengths.

Copy the digest

Grab the hex output for checksums, commit signatures, or cache keys.

Common questions

Frequently asked questions

Is my text sent to a server?

No. Hashing runs locally in your browser tab using JavaScript, so nothing you type ever leaves your device.

Which algorithm should I use?

SHA-256 is the safe default for checksums and integrity checks. MD5 and SHA-1 are only useful for legacy compatibility — avoid them for anything security-sensitive.
