Hi everyone,

I am trying to write a SQL function to allow me to encrypt and decrypt between integers and bits.

Could any one provide some guidance toward how to write this function?

Thanks a lot - Sam

The most simple way is using Hashbyte with MD5,SH1 etc algorithm.But the drawback is it cannot be decrypted into its original format but you can check its existence


declare @tbl table(id int)
insert @tbl
select HASHBYTES('MD5','MyPassword')

select * from @tbl where id= HASHBYTES('MD5','MyPassword')
select * from @tbl where id= HASHBYTES('MD5','NotMyPassword')

PBUH
