[RESOLVED] session_id length?

[lobobr]

Greetings.

I'd like to know if the session_id have always the same length. The reason is I'll store the sessions id's in a database, so should I make the db field a CHAR(x) or the length may vary so I should make a VARCHAR(x)?

If the length IS constant, wich value should I put on x?

TIA,

They should be of constant length, either 128 bits (32 characters) or 160 bits (40 characters) depending on whether MD5 or SHA1 is used to generate them respectively.
