SHA256 Hash Generator

SHA256 hash function generator generates a SHA256 hash (SHA256 Encode) which can be used as secure 64 char password or used as Key to protect important data such as personal information, money transactions and much more.

It will generate 64 characters of SHA256 hash string and it can not be reversible.

SHA256 Generator can be called as SHA256 Checksum online or SHA256 Calculator.

How to Generate SHA256 Hash?

• Step 1: Enter the Plain or Cypher Text.
• Step 2: Click on Generate SHA256 HASH Online.
• Step 3: Use Copy to Clipboard functionality to copy the generated SHA256 hash.

What is SHA2 HASH?

SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.

SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. SHA-256 and SHA-512 are novel hash functions computed with eight 32-bit and 64-bit words, respectively. They use different shift amounts and additive constants, but their structures are otherwise virtually identical, differing only in the number of rounds. SHA-224 and SHA-384 are truncated versions of SHA-256 and SHA-512 respectively, computed with different initial values. SHA-512/224 and SHA-512/256 are also truncated versions of SHA-512, but the initial values are generated using the method described in Federal Information Processing Standards (FIPS) PUB 180-4.

SHA-2 was first published by the National Institute of Standards and Technology (NIST) as a U.S. federal standard (FIPS). The SHA-2 family of algorithms are patented in US. The United States has released the patent under a royalty-free license.

As of 2011, the best public attacks break preimage resistance for 52 out of 64 rounds of SHA-256 or 57 out of 80 rounds of SHA-512, and collision resistance for 46 out of 64 rounds of SHA-256.
