Hash Generator (MD5/SHA-1/SHA-256)
Computes the MD5, SHA-1, and SHA-256 hash of your text in real time. All processing happens in your browser, and nothing you type is ever sent to a server. Need a random string instead? Try thePassword Generatoras well.
Notes
- MD5 and SHA-1 have known vulnerabilities and should not be used for security-sensitive purposes such as password storage.
- Input is matched exactly, including line breaks and spaces.
Glossary
Hash value
A fixed-length string computed from input data using a set procedure. The same input always produces the same hash, but you cannot reverse a hash back into the original data.
MD5
An older hash function. Methods for deliberately producing two different inputs with the same MD5 hash (collisions) are well known, so avoid it for security-sensitive uses such as tamper detection or password storage.
SHA-1
Widely used as MD5's successor, but it also has known weaknesses and is now discouraged for security purposes.
SHA-256
Part of the SHA-2 family. It is still considered secure and is used widely, including in digital certificates and blockchains.
