    Orc 250 - Create sha256 mask

     Masking strategy that masks String, Varchar, Char and Binary types
    as SHA 256 hash.
    
    For String type:
     All string type of any length will be converted to 64 length SHA256 hash.
    
    For Varchar type:
     For Varchar type, max-length property will be honored i.e.
     if the length is less than max-length then the SHA256 hash will be truncated
     to max-length. If max-length is greater than 64 then the output is the sha256
     length, which is 64.
    
    For Char type:
     For Char type, the length of mask will always be equal to specified max-length.
     If the given length (max-length) is less than SHA256 hash length (64)
     the mask will be truncated.
     If the given length (max-length) is greater than SHA256 hash length (64)
     then the mask will be padded by blank spaces.
    
    For Binary type:
     All Binary type of any length will be converted to 64 length SHA256 hash.
