SOLVED!
As the instructions never mentioned that the Encryption needed to be stored as "key 2" before doing Keytocard, I didn't know this.
Hi All,
I have a GPG certificate with SC as part of primary key and A & E as two separate sub keys.
Code:
pub 2048R/XXXXXXXX created: 2017-01-27 expires: never usage: SC
trust: ultimate validity: ultimate
sub 2048R/YYYYYYYY created: 2017-01-27 expires: never usage: A
sub 2048R/ZZZZZZZZ created: 2017-01-27 expires: never usage: E
trust: ultimate validity: ultimate
sub 2048R/YYYYYYYY created: 2017-01-27 expires: never usage: A
sub 2048R/ZZZZZZZZ created: 2017-01-27 expires: never usage: E
But when trying to import the keys to the Yubikey 4, I only get the options of SC and A.
The option for Encryption is not displayed?
What can be the reason?
Code:
gpg> keytocard
Really move the primary key? (y/N) y
Signature key ....: E45F <removed>
Encryption key....: [none]
Authentication key: 19E7 >removed>
Please select where to store the key:
(1) Signature key
(3) Authentication key
Your selection?

I use the Encryption key in emails and it works as expected.
