supports the encryption feature of the Recovery Management for Db2 solution.

Important

Because the encryption feature is part of the Recovery Management for Db2 solution, making encrypted copies requires use of a valid Recovery Management for Db2 solution password. For more information about encryption and Recovery Management for Db2, see the Recovery Management for Db2 documentation.

is based on standard secret key encryption algorithms. You can select encryption based on one of the following standard algorithms:

  • The ANSI Data Encryption Algorithm (DEA) with a 64-bit key

    This is the default algorithm (Data Encryption Algorithm, ANSI-X3.92.1981, American National Standards for Information Systems)

  • The Triple Data Encryption Standard (TDES) with a 128-bit key

  • The Advanced Encryption Standard (AES) with a 128-bit key

    This algorithm refers to the Advanced Encryption Standard, Federal Information Processing Standards Publication 197, November 26, 2001.
