1. Make public key file (Host side)

> TestDrive_LM export "PublicKey"

You can see the encypted ".TestDrive.public_key" file in the same working folder.
For "PublicKeyName", enter the desired key sentence appropriately.
"PublicKeyName" must not be shared with unauthorized persons, instead share the encrypted public key file ".TestDrive.public_key".

2. Encrypt your files (Host side)

> TestDrive_LM encrypt yourfile.ext ...

(This operation can be executed only when the ".TestDrive.public_key" file exists in the current folder or its parent folder.)
You can see the ".TestDrive.ext.encrypted" file in the same working folder.

3. Generate & Register private key from private hash (Client side)

First, you must check private hash code.

> TestDrive_LM check
Your public key : C:/~/.TestDrive.public_key
*E: No private key. Contact your license manager with following your private hash code.

    - Your private hash : 538E1CC5EFF907074FCF25C82BAC2B772DED23F47DB235FC293018150A21C5A13900FCF928559443738E6626EA8C3D48346F8CF6568D5DDCF8C06B4445D033A4

The client side has no license rights to decrypt, and each client PC has a different private hash code.
The client needs to generate private_key from private hash code to decrypt the files.

Then, generate private code from private hash

> TestDrive_LM hash "PublicKey" 538E1CC5EFF907074FCF25C82BAC2B772DED23F47DB235FC293018150A21C5A13900FCF928559443738E6626EA8C3D48346F8CF6568D5DDCF8C06B4445D033A4

SHA256 Private key : D140E28AB0FD52EE3AC3F26E7FC81FCCDA6054C2EFE53EF124EEF5A9206AF93D

Now you've got a private key "D140E28AB0FD52EE3AC3F26E7FC81FCCDA6054C2EFE53EF124EEF5A9206AF93D"

And you must register the private code like this.

> TestDrive_LM register D140E28AB0FD52EE3AC3F26E7FC81FCCDA6054C2EFE53EF124EEF5A9206AF93D
*I: Done.

4. Decrypt your files

> TestDrive_LM decrypt yourfile.ext.encrypt ...

Now you can find decrypted file "yourfile.ext".
