2 Click Key > Create New Key.
3 Select PGP Key, then click Continue.
4 Specify your full name, e-mail address, and comment, if needed.
5 Click Advanced key options to specify the following advanced options for the
key.
Encryption Type
Specifies the encryption algorithms used to generate your keys. DSA ElGamal
is the recommended choice because it lets you encrypt, decrypt, sign, and
verify as needed. Both DSA (sign only) and RSA (sign only) allow only
signing.
Key Strength
Specifies the length of the key in bits. The longer the key, the more secure
it is (provided a strong passphrase is used), but keep in mind that performing
any operation with a longer key requires more time than it does with a
shorter key. Acceptable values are between 1024 and 4096 bits. At least
2048 bits is recommended.
Expiration Date
Specifies the date at which the key will cease to be usable for performing
encryption or signing operations. You will have to either change the expira-
tion date or generate a new key or subkey after this amount of time passes.
Sign your new key with your old one before it expires to preserve your trust
status.
6 Click Create to create the new key pair.
The Passphrase for New PGP Key dialog box opens.
7 Specify the passphrase twice for your new key, then click OK.
When you specify a passphrase, use the same practices you use when you create
a strong password. The main difference between a password and a passphrase is
that spaces are valid characters in a passphrase.
