# Installing CyberSource Toolkit for i

Before installing CyberSource Toolkit for i, you should confirm that your IBM i is able to support TLS 1.2 and CyberSource's required secure cipher suites. Please see the [security requirements page](https://isupport.katointegrations.com/cti/cs_security_requirements.md) for more information.

1. Unzip the downloaded file to `C:\temp` (or the directory of your choice).

2. Create the \*SAVF to upload to on your IBM i:

    `CRTSAVF FILE(QGPL/CTI) AUT(*ALL)`

3. FTP the file CTI.SAVF from your PC to the IBM i. Open a command prompt (Start → Run → enter 'cmd' and hit enter). Type the following into the command prompt, replacing the IP address with that of your IBM i. When prompted, enter your IBM i username and password.
    1. `ftp 123.456.789.123`
    2. `binary`
    3. `lcd c:\temp`
    4. `quote site namefmt 0`
    5. `cd QGPL`
    6. `put CTI.savf CTI.savf`
    7. `quit`

4. Restore the library from the \*SAVF:

    `RSTLIB SAVLIB(CTI) DEV(*SAVF) RSTLIB(CTI) SAVF(QGPL/CTI)`

5. Add the library to your library list:

    `ADDLIBLE CTI`

6. Restore the IFS \*SAVF:

    `RST DEV('/qsys.lib/cti.lib/ifs.file') OBJ(('/ktprod/cti' *INCLUDE '/ktprod/cti')) CRTPRNDIR(*YES) PRNDIROWN(QSYS) ALWOBJDIF(*ALL)`

7. Apply your license key:

    `APYLIC LICKEY(<<insert key that was emailed to you>>) PRODUCT(CTI)`

8. Follow the below guide to import the required SSL certificates to your system:

9. Follow the below guide to create a Cybersource P12 certificate:

    [Create Cybersource P12 Certificate](https://isupport.katointegrations.com/cti/create_cs_p12_certificate.md)

10. Once you have created the P12 certificate and uploaded it to your IBM i's IFS, use the WRKCTICERT command to import it:
