RSA only enable to sign

[Robert J. Hansen]

There are some Spanish-speakers on this list who might be able to give
you a Spanish answer.  If you don't mind an English answer, I'll try to
answer it.

> Can you help me with the next: why I have RSA only to sign¿?

You need to add an RSA encryption subkey.  Go ahead and create a
sign-only RSA key.  Then:

	gpg --edit-key [my key ID] addkey

At the prompt, choose "(6) RSA (encrypt only)".  It may be numbered
differently on your machine.

Go through the rest of the steps and you will have add an RSA encryption
 subkey.  Send the updated key on to the keyserver network and your
friends can now use that encryption subkey to encrypt data meant for you.
