GPG keys have a variety of different uses from sending encrypted emails to verifying git commits. Here I'll show how easy it is to create a public/private key-pair. Assuming you have the `gpg` client installed.
|
|
|
|
Type the following command
|
|
|
|
```bash
|
|
gpg --full-gen-key
|
|
```
|
|
|
|
This will then show
|
|
|
|
```

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)
|
|
Your selection? 1
|
|
```
|
|
|
|
I selected the default option.
|
|
|
|
```
|
|
RSA keys may be between 1024 and 4096 bits long.
|
|
What keysize do you want? (3072) 4096
|
|
Requested keysize is 4096 bits
|
|
```
|
|
|
|
I went for the highest available option.
|
|
|
|
```
|
|
Please specify how long the key should be valid.
|
|
0 = key does not expire
|
|
<n> = key expires in n days
|
|
<n>w = key expires in n weeks
|
|
<n>m = key expires in n months
|
|
<n>y = key expires in n years
|
|
Key is valid for? (0) 1y
|
|
```
|
|
|
|
It's highly recommended that you set an expiration date. I usually set it for around 1-3 years.
|
|
|
|
```
|
|
Key expires at Mon 11 Apr 2021 06:42:01 PM EDT
|
|
Is this correct? (y/N) y
|
|
```
|
|
|
|
Quick sanity check.
|
|
|
|
```
|
|
GnuPG needs to construct a user ID to identify your key.

More sanity checks.

|
We need to generate a lot of random bytes. It is a good idea to perform
|
|
some other action (type on the keyboard, move the mouse, utilize the
|
|
disks) during the prime generation; this gives the random number
|
|
generator a better chance to gain enough entropy.
|
|
```
|
|
|
|
Do as it says, start going crazy.
