Since sha256 returns a hexadecimal representation, 4 bits are enough to encode each character (instead of 8, like for ASCII), so 256 bits would represent 64 hex characters, therefore you need a varchar (64), or even a char (64), as the length is always the same, not varying at all. And the …

WebIn other words, if you compare hash values from a table – computed at different times – you can determine if that table’s data has been updated or changed in anyway. In the following query, I calculate and return the hash value for the table named “tablename_to_check”, which would return a number something like this: 940335729.
WebNov 9, 2024 · SHA-1 is a 160-bit hash. SHA-2 is actually a “family” of hashes and comes in a variety of lengths, the most popular being 256-bit. The variety of SHA-2 hashes can lead to a bit of confusion, as websites and authors express them differently.
