When a symmetric key is created we have the option to encrypted it by using at least one of the following: certificate, password, symmetric key, asymmetric key or EKM.
When a password is used, it it said that:
When a symmetric key is encrypted with a password instead of a certificate (or another key), the TRIPLE DES encryption algorithm is used to encrypt the password. Because of this, keys that are created with a strong encryption algorithm, such as AES, are themselves secured by a weaker algorithm.
So, using password is not best way to protect it. I was not able to find any pros and cons for using the other techniques.
Can anyone tell is there are difference from security or performance matter or it is just a matter of choice?
