How to use:
Simply input the plaintext you would like to hash into the top box and an output will appear in the box below; it contains the hash value made with a bit length the same as the number in the algorithm name, e.g. SHA-256 produces a hash with a bit-length of 256.
The hash produced here is in the form of hexadecimal. Another way to find the bit-length of the hash is by going from hexadecimals to bits. The conversions are as follows:
1 hexadecimal character = 4 bits
1 base64 character = 6 bits
1 text character = 8 bits
SHA3-512
Information
SHA-3 is the latest member of the Secure Hash Algorithm family of standards (as of 2021), released by NIST on August 5, 2015. Although part of the same series of standards, SHA-3 is internally different from the MD5-like structure of SHA-1 and SHA-2.
The Secure Hash Algorithm version 3 fixes flaws in the now-standard SHA-2 cipher. Despite this, it hasn't as of yet been made the standard.
SHA-3 is a subset of the broader cryptographic primitive family Keccak.
