SHA1/SHA2 Hash generator

Convert a string using the SHA1/SHA256/SHA384/SHA512 algorithms and generate hash values.

Hash value generation is performed in the browser, so rest assured that the entered data is not transmitted to the server or stored anywhere. Please feel free to use it with confidence.

SHA(Secure Hash Algorithm)

The Secure Hash Algorithm (SHA), abbreviated as SHA, is also known as a cryptographic hash function. It has been designated as the standard hash function, Secure Hash Standard, by the National Institute of Standards and Technology (NIST) in the United States. SHA transforms any large data block into a fixed-size output (typically much shorter than the input).

Warning

SHA-1 is now considered vulnerable and should not be used for cryptographic applications.
