I have a 4096bits primary key with two 2048 bits subkeys. I want to move the whole shebang to my yubikey 4. I migrated the subkeys without a major problem, but the primary key migration fails: Code: gpg> keytocard Really move the primary key? (y/N) y Signature key ....: xxxxx Encryption key....: xxxxx Authentication key: [none] Please select where to store the key: (1) Signature key (3) Authentication key Your selection? 3 You need a passphrase to unlock the secret key for user: xxxxxx 4096-bit RSA key, ID xxxxx, created xxxxxx <admin pin is asked here, I give it> gpg: error writing key to card: Invalid value The primary key is 4096 RSA with SCA capability. |
