md5() Sizes... -[RESOLVED]-

[Electroman]

Is there anyway to work out how long a string will be after you use md5() on it? Like for a password field I know the password will be between 6-12 characters but how big should I be making the field on the database to ensure it fits, without wasting too much space.

An MD5 hash is a 128 bit number, that's 16 bytes. As a hexadecimal string, as PHP's md5 returns it, that's 32 characters.
