I had the same issue so wrote this down when I figured it out
gpg2 --quick-generate-key hello@example.com ed25519 default 0
gpg2 --quick-add-key <FINGERPRINT> ed25519
gpg2 --list-keys --with-subkey-fingerprint --keyid-format long
I remember on some distros I had to add --expert, never checked why. Maybe was an old version.
gpg --expert --full-gen-key
Thank you @Anafabula@discuss.tchncs.de ! it works !
Please select what kind of key you want:
(1) RSA and RSA (default)
(2) DSA and Elgamal
(3) DSA (sign only)
(4) RSA (sign only)
(7) DSA (set your own capabilities)
(8) RSA (set your own capabilities)
(9) ECC and ECC
(10) ECC (sign only)
(11) ECC (set your own capabilities)
(13) Existing key
(14) Existing key from card\
I'm wondering whats is the option: (9) ECC and ECC ?? I found nothing in their documentation :/
What distro and version of that distro are you using? Did you install gpg from the repository or elsewhere? What version of gpg are you running?
Unless you're working with embedded chips with very small storage space, I'd recommend 4098-bit RSA
~~8096 bit is safer long term as it should remain uncrackable for a longer time.~~
I was thinking you were talking about 2048
Does GPG support it?
Isn't it the default?
Edit: I was mixing up 2048 with 4096
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
