4. Crypt – Encrypt and Decrypt files

This script is a wrapper for openssl that allows you to encrypt and decrypt files quickly and easily.

Enter the password for the file twice.

Encrypting ostechnix.txt...
enter aes-256-cbc encryption password:
Verifying - enter aes-256-cbc encryption password:
Successfully encrypted

The above command will encrypt the given file using AES 256 level encryption. The password will not be saved in plain text. You can encrypt .pdf, .txt, .docx, .doc, .png, .jpeg type files.

To decrypt the file, use the following command:

crypt -d [encrypted file] [output file]

Example:

crypt -d encrypt_ostechnix.txt ostechnix.txt

Enter the password to decrypt.

    Hi, thank you for the useful scripts, I’m currently using the ytview one. Just a little suggestion from me, it would be better if you could show the channel name & duration of the video too when searching for one, so the search result would look like this: [ChannelName] – [VideoTitle] – [VideoDuration]
