The Real David and Solomon! On the other hand, it has been discovered by some researchers that this Star of David (also called Shield of David and Seal of Solomon) was NOT a symbol relating to either the Biblical King David or Solomon, but to Solomon ben Duji the Khazar, and his son, David al-Roy.
SHA-256 and SHA-512 are novel hash functions computed with 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.HA-2 was published in 2001 by the NIST as a U.S. federal standard (FIPS).
SHA-1 produces a 160- bit (20- byte) hash value known as a message digest. A SHA-1 hash value is typically rendered as a hexadecimal number, 40 digits long. SHA-1 is a member of the Secure Hash Algorithm family. The four SHA algorithms are structured differently and are named SHA-0, SHA-1, SHA-2, and SHA-3.SHA-0 is the original version of the 160-bit hash function published in 1993 under the name SHA: it was not adopted by many applications.HA-2, published in 2001, is significantly different from the SHA-1 hash function. In 2005, cryptanalysts found attacks on SHA-1 suggesting that the algorithm might not be secure enough for ongoing use. NIST required many applications in federal agencies to move to SHA-2 after 2010 because of the weakness.
