    Question

  • Hello every one,

    Can any one help me out in understanding what really is the difference between SHA1,SHA2,MD4 and MD5 algorithms in terms of data of  a table.

    Which is the precise situation to opt which algorithm. ?

    How HASH_BYTES() treats each Algorithm?

    Please Help

  • Hi Pavan-SqlServer,

    As to the difference between these algorithms, please view the article: Comparison of cryptographic hash functions. You can choose an appropriate algorithm based on the comparison.

    For using HASHBYTES with MD2, MD4, MD5, SHA, or SHA1, please take a look at: HASHBYTES (Transact-SQL).
