Use seahorse in Ubuntu to encrypt and sign files

Some readers recently reported to us that the truecrypt project was terminated. Is there any good replacement software on linux? After seeing the request, xiaobian immediately began to collect information, sort out and test it in person, and found a simple and easy-to-use file encryption method in Linux.

The software we use here is seahorse, A GnuPG graphical front-end (for details about GnuPG, refer to Wikipedia). This software can be used on computers using gnome desktops, of course, Ubuntu (default unity desktop) can also be used. The following describes how to use seahorse to encrypt and sign files in Ubuntu.

Click continue.

Enter the full name and other information. Note: The full name can be Chinese or English, but the full name must be at least two words. You can select RSA or DSA as the encryption type; the larger the number of self-selected keys, the more secure the Key is. The validity period can never expire.
