    I am using EncryptByPassPhrase(http://technet.microsoft.com/en-us/library/ms190357(v=sql.105).aspx) for encrypting some columns . But if i want to change the passphrase in future then how can i change it?

    You decrypt the entire column, re-encrypt with the new passphrase and change whereever that passphrase is stored in the app/stored proc.
