Strong encryption


Strong database encryption technology makes a database inoperable and inaccessible without a key (password). An algorithm encodes the information contained in your database and transaction log files so they cannot be deciphered.

Caution    

Protect your key! Be sure to store a copy of your key in a safe location. A lost key will result in a completely inaccessible database, from which there is no recovery.

The encryption algorithm

The algorithm used to implement SQL Anywhere strong encryption is AES: a block encryption algorithm chosen as the new Advanced Encryption Standard (AES) for block ciphers by the National Institute of Standards and Technology (NIST). It has many properties that lend itself well to encryption of SQL Anywhere databases in terms of performance and size.

You can also specify a separate FIPS-approved AES algorithm for strong encryption using the AES_FIPS type. When the database server is started with the -fips option, you can run databases encrypted with AES or AES_FIPS strong encryption, but not databases encrypted with simple encryption. Unencrypted databases can also be started on the server when -fips is specified. See -fips server option.

The SQL Anywhere security option must be installed on any computer used to run a database encrypted with AES_FIPS.

Separately licensed component required

ECC encryption and FIPS-certified encryption require a separate license. All strong encryption technologies are subject to export regulations.

See Separately licensed components.

Note

FIPS is not available on all platforms. For a list of supported platforms, see the Separately Licensed Components sections of the SQL Anywhere, UltraLite, and MobiLink tables in [external link] SQL Anywhere 10.0.1 Components by Platform
