Appropriate datatype to store encrypted data

[hare_srinivasa]

Hi, what is the best suited datatype for storing data encrypted using AES_ENCRYPT and AES_DECRYPT?

It would be a blob.

Blob vs. VarBinary which one would perform better? I would like to add this field to an already existing database table that is read and written to quite often.

if you know the length varbinary, otherwise blob
