Encryption tools
Encryption is a method of using an algorithm to encrypt data so that it is unusable by third parties.
Only by using the right key -a secret password- can the original data be decrypted again.
Encryption of data
Encrypting your laptop's hard disk (system drive) is mandatory.
- Windows: BitLocker (included with the operating system)
- macOS: If you are using a Mac that does not have Apple silicon or the T2 chip, you need to enable FileVault to encrypt your data.
Guide on using FileVault
- Linux: encrypt your hard disk with LUKS.
- Veracrypt is an open source tool that lets you encrypt files or even entire disks. You can download an installation file from the Veracrypt website.
Encryption of files and folders or volumes, including for internal and external cloud storage, also for e-mail attachments when the e-mail message itself is not encrypted.
Quickly encrypt one or a few files: symmetric encryption (password-based).
NOTE: It is very important to remember your password because you will need it to access your encrypted data.
Container encryption: creating an encrypted file container or encrypting an external (physical) hard disk or USB stick
- Veracrypt is an open source tool that lets you encrypt files or even entire disks. You can download an installation file from the Veracrypt website.
Encryption of e-mail
Digital signature and encryption of e-mail messages with public key cryptography
- S/MIME: user-friendly email encryption (and digital signature) standard supported in virtually all modern mail programs (not webmail).
- GnuPG (GNU Privacy Guard) is an open source alternative to S/MIME based on the OpenPGP standard.
- S/MIME
- OpenPGP, the open-source implementation of Pretty Good Privacy (PGP)
