Enabling Job Encryption for InfoPrint Manager for Linux

To enable Job Encryption for InfoPrint Manager servers:

Stop all running instances of InfoPrint Manager. In interoperated environments, stop all running instances of InfoPrint Manager on all interoperated machines.
Copy the sample configuration file, ipm-file-encryption.cfg, from /usr/lpp/pd/cfg-samples/file-encryption directory to /var/pddir/default_cell/crypto directory.
Uncomment and set EnableFileEncryption to 1.
Uncomment and set Cipher to the desired cipher to use for encryption.
- The list of available ciphers can be obtained by running the following command:
```
openssl-ipm enc -ciphers
```
  Do not include the first character ('-') from the cipher name.
- If you use an AES cipher, having a processor that supports hardware encryption, AES instruction set, speeds up the encryption/decryption time. For the AES instruction set, see https://software.intel.com/content/www/us/en/develop/articles/intel-advanced-encryption-standard-instructions-aes-ni.html.
Run pdenc_jobs as the user that runs InfoPrint Manager or root. In interoperated environments, run pdenc_jobs sequentially on all interoperated machines.
Start all instances of InfoPrint Manager or reboot.

Important:

Do not change the cipher in the ipm-file-encryption.cfg configuration file once encryption has been enabled. To change the cipher, follow the procedure in Disabling Job Encryption for InfoPrint Manager for Linux, change the cipher in the ipm-file-encryption.cfg configuration file, and then follow the procedure to enable Job Encryption for InfoPrint Manager.
Do not remove the ipm-file-encryption.dat file once encryption has been enabled. This file is stored in the same directory as the ipm-file-encryption.cfg configuration file.
Before running pdenc_jobs, make sure that there is at least 1.5* (size of jobs + rip files) free space available on the partition where jobs are stored.
