Hash Generator: A hash generator converts any text or string into a fixed-length cryptographic hash such as MD5, SHA-1, SHA-256 or SHA-512. Type your input and copy the hash instantly — all computed in your browser, so sensitive text is never sent to a server.
Frequently Asked Questions
What is a hash function?
A hash function turns input of any length into a fixed-length string of characters. The same input always produces the same hash, but the process is one-way — you cannot reverse a hash back to the original text.
What is the difference between MD5 and SHA-256?
MD5 produces a 128-bit hash and is fast but cryptographically broken, so it should only be used for checksums, not security. SHA-256 produces a 256-bit hash and is a current, secure standard for integrity and passwords.
Is a hash the same as encryption?
No. Encryption is reversible with a key, while hashing is one-way and cannot be decrypted. Hashes are used to verify integrity and store password fingerprints, not to hide recoverable data.
Are my strings uploaded when I generate a hash here?
No. SnoopTool computes hashes entirely in your browser with JavaScript, so your input text is never uploaded, logged, or transmitted anywhere.
