Notes
- Newer versions of Debian use the sha-512 there is a tool called mkpasswd that will create compatible passwords.
File encryption
Encrypt
openssl enc -aes-256-cbc < <File> > <File>.aes enter aes-256-cbc encryption password: Verifying - enter aes-256-cbc encryption password:
Decrypt
openssl enc -d -aes-256-cbc -in <File>.aes > <File> enter aes-256-cbc decryption password:
