Hash Length of SHA 265

It is important to note that any hash algorithm always returns a hash of fixed length. 
SHA256 returns a hash value that is 256 bits - i.e. 32 bytes. 

These 32 bytes are typically represented as a hexademical string of 64 bytes. 
Hence to store a SHA256 hash, we just need 64 bytes (in database terms - varchar(64)).
