ABSTRACT:
Provided are a method, system, and article of manufacture for encrypting and decrypting database records. Encryption metadata is provided for a database file having fields, wherein the encryption metadata indicates at least one encryption key for the file. A request is received to perform a read or write operation with respect to a record including the fields for the database file. A determination is made from the encryption metadata of the at least one encryption key for the database file. The determined encryption key is used to encrypt or decrypt for the read or write operation with respect to at least one of the fields in the database file.
