EDGE–Command Line User Guide
The type of key you want to generate can depend upon what kind of OpenPGP
client the person or organization you want to communicate securely with is using.
Keep in mind that older versions of OpenPGP clients handle only specific formats of
RSA keys and some newer OpenPGP clients only handle DSS/DH keys, the ElGamal
variant of Diffie-Hellman technology. EDGE supports both RSA and DSS/DH keys.
Also keep in mind that there are two different formats of RSA keys- RSA and RSA
Legacy:
§
RSA: If you select RSA, EDGE generates the new standard RSA key
pair format by default. This means keys compatible with newer
OpenPGP clients. The new RSA key format supports features
previously available only to DSS/DH keys. The new RSA key
format enables you to have a primary key for signing and a subkey
to encrypt data. In addition the encryption key (the subkey) can be
revoked or have a different expiration date than its primary key. A
new subkey can always be added to a primary key and can be used
for encrypting data. New RSA keys are compatible with newer
versions of OpenPGP. These keys are not compatible with older
PGP clients not compliant with RFC 2440 such as PGP 2.6.x. Old
OpenPGP clients are compliant with RFC 1991 only, not RFC 2440.
§
RSA Legacy Format: EDGE gives you the option to generate RSA
Legacy keys (see next chapter) which are compatible with older
versions of OpenPGP. Old OpenPGP clients are compliant with RFC
1991 only, not RFC 2440. To generate an RSA Legacy key pair
go to the next chapter of this manual.
If no key type is specified, EDGE directly asks you to select the main name (User
ID) of your key. By convention, a key name is formed by your real name and by
your email address.
For instance, if your name is “Robert J. Smith” and if your email address is
[email protected], your User ID could be:
“Robert J. Smith <[email protected]>”.
