PGP Encryption Procedures
Step 1: Generate API Key
$gpg –gen-key
a. Select (1) RSA and RSA
- hit enter key
b. Select 2048 as keysize
- hit enter key
c. Specify how long the key should be valid
d. Is this correct? (y/N):
- type y
e. Real Name:
- type firstname lastname
f. Email address:
- type email address
g. Comment:
- type any comment
h. Enter passphrase:
- enter a phrase with non related words and remember it
i. Repeat passphrase
j. Wait for the result by operating computer in various ways.
k. On finish, you can see the user-id(uid) like “firstname lastname (comment) < email address >”
You can also check “uid” with the command “gpg –list-key”
Note: It will take some time to get the uid. Please be patient.
Step 2: Create public key
$ gpg –export -a “uid” > public.key
Step 3: Create private key
$ gpg –export-secret-key -a “uid” > private.key
Step 4: Encrypt a file
$ gpg –encrypt –output output-file –recipient “uid” input-file
Note: Generally, the file will be encrypted by Konnektive.
Step 5: Decrypt a file
#### $ gpg –decrypt –output output-file input-file
type passphrase
