Lockdown

lockdown is a file encryption tool that takes, as input, a set of plaintext files and replaces them with encrypted counterpart files, typically with a file extension of (.lkd), and vice versa.

When a file is successfully encrypted, the plaintext file is deleted from the file system, leaving only the (.lkd) encrypted file remaining.

The same is true of the reverse, successfully decrypting a (.lkd) file will produce a plaintext counterpart and delete the encrypted file from the file system.
