Here you can calculate online SHA3-256 hashes for your strings. Put your string into form below and press "Calculate SHA3-256 hash". As a result you will get SHA3-256 hash of your string. If you need another hash calculators, for example: HAVAL128-5, HAVAL160-3, SHA224 or SNEFRU you can find it into appropriate section.
SHA-3 (Secure Hash Algorithm 3) is the latest member of the Secure Hash Algorithm family of standards, released by NIST on August 5, 2015. Although part of the same series of standards, SHA-3 is internally quite different from the MD5-like structure of SHA-1 and SHA-2.
SHA-3 is a subset of the broader cryptographic primitive family Keccak, designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, building upon RadioGatún. Keccak's authors have proposed additional uses for the function, not (yet) standardized by NIST, including a stream cipher, an authenticated encryption system, a "tree" hashing scheme for faster hashing on certain architectures, and AEAD ciphers Keyak and Ketje.
Keccak is based on a novel approach called sponge construction. Sponge construction is based on a wide random function or random permutation, and allows inputting ("absorbing" in sponge terminology) any amount of data, and outputting ("squeezing") any amount of data, while acting as a pseudorandom function with regard to all previous inputs. This leads to great flexibility.
NIST does not currently plan to withdraw SHA-2 or remove it from the revised Secure Hash Standard. The purpose of SHA-3 is that it can be directly substituted for SHA-2in current applications if necessary, and to significantly improve the robustness of NIST's overall hash algorithm toolkit.
You've visit right place if you want to calculate SHA3-256 hashes. Put string or even text into String to encode field above and press "Calculate SHA3-256 hash". You will get SHA3-256 hash of your string in seconds. You can also copy this hash right to your clipboard using the appropriate button.
Keep in mind that our website has a lot of other calculators, like MD2, MD4, MD5, SHA1, SHA224, SHA256, SHA384, SHA512-224, SHA512, RIPEMD128, RIPEMD160, RIPEMD256, RIPEMD320, WHIRLPOOL, SNEFRU, SNEFRU256, GOST, ADLER32, CRC32, CRC32B, FNV132, FNV1A32, FNV164, FNV1A64, JOAAT, etc. So all what you need to calculate any of these hashes is remeber our web site address - SHA256Calc.com
