 ==== Key creation ====
+In order to create a key pair type in terminal the following: ''gpg --full-generate-key''
+{{documentation:gpg-create-1.png}}
+Choose first method e.g. RSA and RSA.
+{{documentation:gpg-create-2.png}}
+Choose 4096 bits key long (it's more technically secure).
+{{documentation:gpg-create-3.png}}
+We'd recommend to choose 2 year lifespan.
+{{documentation:gpg-create-4.png}}
+Finally type your name, email and comment for the key pair (this is optional, you can leave it blank). You will be asked to type a passphrase to encrypt your private key with.
+**NOTE:** Don't forget your passphrase, you can loss your private key without passphrase.
+After this please be patient, some time is required to generate a key pair.
 ==== Import public key ====
+To import someone's else public key all you need is type in terminal ''gpg --import <filename of the public key>''
 ==== Commit your own public key ====
+To publish your public key you need to provide it first. To get a file with your own public key, just type the following in terminal: ''gpg --export --armor 'yourname@example.com' > yourname.asc''
 ==== Sign the data ====
 ==== Data encryption ====
+=== Encrypt ===
+To encrypt some data (e.g. file in the example below) you need to know a recipient and his/her public key. On the example below we're encrypting data in file secret.pdf for alice@askele.com: ''gpg -r 'alice@askele.com' -e secret.pdf''
+Result file will be secret.pdf.gpg
+=== Decrypt ===
+In order to decrypt some data (e.g. file) you need to type the following (assuming you receive secret.pdf.gpg): ''gpg -d secret.pdf.gpg > secret.pdf''
+Result will be stored in secret.pdf which is a plain (decrypted) data.
