Configuration Files 1

The configuration files contain the configuration information for your

Q-EKM server installation.

The two configuration files are named:

• ClientKeyManagerConfig.properties

• KeyManagerConfig.properties

The configuration files are located in the root QEKM directory as follows:

Tape Drive Table 1

The tape drive table is used by Q-EKM to keep track of all the tape drives

that have ever requested a key from the Q-EM server. The tape drive

table is a non-editable, binary file. Q-EKM automatically adds new/

replaced tape drives to the drive table.

Encryption Keys

An encryption key is typically a random string of bits generated

specifically to scramble and unscramble data. Encryption keys are created

using algorithms designed to ensure that each key is unique and

unpredictable. The longer the length of key used, the harder it is to break

the encryption code.

The IBM LTO-4 and LTO-5 method of encryption uses 256-bit AES

algorithm keys to encrypt data. 256-bit AES is the encryption standard

currently recognized and recommended by the U.S. government, which

allows three different key lengths. 256-bit keys are the longest allowed by

AES.

Caution: Do not edit these files. If you make a mistake when

altering the configuration files, you could lose access to

your keystore and be unable to encrypt or restore data.
