First, can anyone point me to a good "mcrypt" primer or tutorial?
Second, how can I determine what type and length I should make a
database field that will hold encrypted data? Is there some table
somewhere which tells how long a resulting encrypted field will be
based on the encryption type and/or length of the plaintext field?
Example: If I have a 20 character field and want to use Triple
DES to encrypt it, can I find out how long the resulting
field will be - what is the longest it will be? Will
the resulting encrypted field always be the same length?
Should I make the data type some variation of "text" or
"varchar"?
TIA.
