Encryption

Encrypting the data or files before a transfer is often necessary to prevent the data from being read if intercepted in transit

Windows

PS C:\htb> Import-Module .\Invoke-AESEncryption.ps1

PS C:\htb> Invoke-AESEncryption -Mode Encrypt -Key "p4ssw0rd" -Path .\scan-results.txt

File encrypted to C:\htb\scan-results.txt.aes
PS C:\htb> ls

    Directory: C:\htb

$ openssl enc -aes256 -iter 100000 -pbkdf2 -in /etc/passwd -out passwd.enc

1. Decrypt

$ openssl enc -d -aes256 -iter 100000 -pbkdf2 -in passwd.enc -out passwd
