我使用 创建了经典的身份验证、签名和加密子密钥集gpg，然后将它们移入智能卡 [ledger nano S]，它似乎运行良好，因为我可以看到三个子密钥：
$ gpg --card-status
Serial number ....: 00000000
Signature key ....: F34F 66B8 5D18 A8BC CDD4 C909 4705 D74B 9E2F EFFC
Encryption key....: AD71 E2C1 2E41 C870 3192 D997 78B9 F3F6 7D9B 47DC
Authentication key: D644 70D8 88AB BA93 F9F4 BFE0 2726 E1C4 E4DB E4C3
我是如何到达那里的
基本信息：
$ gpg --version
gpg (GnuPG) 2.2.27
libgcrypt 1.8.8
生成加密、签名和认证子密钥：
$ gpg --expert --edit-key Plup*
gpg> addkey
type: ECC (sign only)
curve: cv25519
Please unlock the card
gpg> addkey
type: ECC (encrypt only)
curve: cv25519
gpg> addkey
type: ECC (set your own capabilities)
allowed actions: Authenticate
curve: cv25519
gpg> save
检查子键：
$ gpg -K Plup*

将子密钥移至新的智能卡插槽（/!\确保不会覆盖主密钥）：
$ gpg --card-status

Serial number ....: 7AC3CFF8
Signature key ....: [none]
$ gpg --edit-key Plup*
gpg> key 1
gpg> keytocard
Signature key
Passphrase:

gpg> key 1
gpg> key 2
gpg> keytocard
Encryption key

我现在遇到的问题
指纹与密钥环看到的指纹相符，但出于某种我不知道的原因，加密密钥存根未到位，而私有子密钥仍然存在于计算机密钥环中。解密时，它仍然要求输入密码而不是智能卡 PIN：
```
$ gpg --with-keygrip --with-subkey-fingerprints -K Plup*

到目前为止我尝试过的
我试图删除私钥但无法强制存根自行创建：

- 我尝试用相同的曲线重新创建一个新的加密子密钥，但其
keytocard行为仍然相同：它完成时没有出现错误，但密钥（下面的新握把）没有移动：
$ gpg-connect-agent 'keyinfo --list' /bye | grep 5CF6DF65EF080B01F774BCC7F8063814CE5DAEF6
S KEYINFO 5CF6DF65EF080B01F774BCC7F8063814CE5DAEF6 D - - - P - - -
答案1
好的，使用不同的曲线可以：
