Hardware license (HL) key deletion

As a licensing information storage, the hardware key's memory can be formatted.

Software license (SL) key deletion

SL-Legacy, SL-Legacy Provisional (VIT no longer provides these types of license keys)

Keys of these types are created with Sentinel SDK 5.х or older versions. Their deletion is possible only by low-level disk formatting. Also, if you extend the volume of your logical disk, there will be a risk of losing your SL-Legacy Provisional key.

SL-AdminMode (VIT uses this type of software license keys)

If SL-AdminMode keys are used (including Unlocked licenses, i.e. demo licenses), all the significant licensing information (for example, license counters) is located in secured storage on your computer. However, you can delete the corresponding certificate file.

To delete the certificate file from your PC:

Find out the identifier of your license key.

To do this, you can open the corresponding c2v-file (the one which you generated for license installation, activation or update) in text editor. The identifier will be written as <hasp id="1234567890">.
Delete the /var/hasplm/installed/107392/*filename*.v2c file (which identifier is equal to your c2v-file's identifier).

Usually there is only one license key installed on the server, so the above-mentioned directory may contain only the one certificate file.
Stop the following processes in the terminal:
```
killall aksusbd
killall haspmld
```
Start the daemons:
```
haspmld -s
aksusbd
```
It is possible to restore the license. If you return the certificate file to the directory from which it was previously deleted, the license will be fully restored. Its counters will keep on tracking information from the point where they stopped due to key deletion (time restrictions are tracked and counted even when the corresponding license key is absent).
