We are implementing SQL column level encryption (that has been around since SQL 2005) to encrypt a few columns in our SQL 2014 database.There are two email fields that were originally defined as varchar(300). When I attempt to save the encrypted value into the new varbinary field, it always stores a NULL value if the original unencrypted text length is greater than 198. I had originally defined the new varbinary field as varbinary(512), but the length of the encrypted output was 514, so I enlarged it to varbinary(max), and it still stores the value as NULL.Here is an update statement applying the output of the encryption to the varbinary(max) field (field is defined as: EmailAddressEnc (varbinary(max), null)).UPDATE Member SET EmailAddressEnc = 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emberNumber = 9999Can anyone explain to me why this statement stores a NULL?Thanks in advance for any assistance.
