NO. An MD5 hash is 16 bytes - 128 bits no more - no less. It can be stored >not truncated< in a CHAR(16+) field or a VARCHAR(16+) field as binary data. As base 64 the same 128 bits occupies 22 bytes (yes that is CHAR(22) or VARCHAR(22)) and as hex it occupies 32 bytes, etc

Short answer yes

Longer answer VARCHAR slows indexing significantly. One varchar field means table is varchar. CHAR is space inefficient but much faster than varchar for select. AAYMMV
