See online : Howto: Install GPG on Jolla Sailfish OS
STEP 1 install pinentry
You have three options:
compile from source
install pinentry-0.8.3-1.armv7hl.rpm or pinentry-0.9.0-10.7.1.jolla.armv7hl.rpm
use warehouse app to search for “pinentry” in OpenRepos and install gnupg-pinentry
STEP 2 open the terminal and install the GnuPG software
[nemo@Jolla ~]$ pkcon install gnupg2Currently this installs version 2.0.4 with a home of /.gnupg
Remember: the executable binary will be gpg2[/rouge] (neither gnupg2, nor gpg).
Supported algorithms:
Pubkey: RSA, ELG, DSA
Cipher: 3DES, CAST5, BLOWFISH, AES, AES192, AES256, TWOFISH
Hash: MD5, SHA1, RIPEMD160, TIGER192, SHA256, SHA384, SHA512, SHA224
Compression: ZIP, ZLIB, BZIP2
STEP 3 use the terminal to create a key
(or import your existing private key with gpg2 --import)
[nemo@Jolla ~]$ gpg2 --gen-key
Please select what kind of key you want:
(1) DSA and Elgamal (default)
(2) DSA (sign only)
(5) RSA (sign only)
Your selection? [Enter]
DSA keypair will have 1024 bits.
ELG-E keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) [Enter]
Requested keysize is 2048 bits
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) [Enter]
<code>Key does not expire at all
<code>Is this correct? (y/N) yYou need a user ID to identify your key; the software constructs the user ID from the Real Name, Comment and Email Address in this form:
"Heinrich Heine (Der Dichter)"
Real name: Davi Ottenheimer
Email address: davi@flyingpenguin.com
Comment:[Enter]
You selected this USER-ID:
"Davi Ottenheimer davi@flyingpenguin.com"
Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O Enter passphrase
Passphrase _*****************_______________
OK CancelTHINK TWICE AND GATHER WISE ADVICE BEFORE PICKING YOUR PASS PHRASE[/rouge] See here (and never write it down anywhere: its only safe place is in your brain).
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.
gpg: key XXXXXXXX marked as ultimately trusted public and secret key created and signed.

Please manage file properties (owner, permissions) very carefully: keep in mind that your smartphone is an always connected thing, most of the time unattended, through a wide variety of wireless equipment you know nothing about.
