Hi. Due to security reason I thought to write down into table passwords of user using MD5 or SHA-1 function for encryption. I'm not sure how these routine really working and have fear that once, in future, if I for example export whole DB to CD and on other computer install new MySQL DB and then import saved data of former DB, will it be "readable", including fields made using MD5? I presume that it shall working but never tried. Someone told me that each new installation of MySQL make some unique key that is used for generation data when MD5 or SHA-1 encryption is involved..?
Is it true or not? Thank you.
