I already hold a UKey containing our company's certificate information, but it is not issued by a contract lock with equal validity. When the user holds a UKey from a CA institution trusted by the contract lock and the certificate in the device is valid. In response to this scenario, the contract lock believes that the UKey held by the user has the same validity as the UKey issued directly by the contract lock, and can directly perform UKey related operations on the contract lock.

I have already completed a corporate certification at a CA institution and do not want to repeat the certification UKey Quick Certification:

When conducting corporate certification, you can switch to [Use UKey Quick Certification] and directly use the valid certificates in the UKey you hold to complete the corporate certification without having to fill in the basic corporate information and sign the authorization letter again, and reduce the waiting process for certification review.

My supplier requires the use of their own UKey for signing Use UKey certificate for signing:

When the UKey device only has a certificate but no seal, users can bind the UKey with the seal in the contract lock system. When signing, the user with seal usage permission will drag the seal into the original text. When completing the signing, the UKey PIN code needs to be verified. After successful verification, the signing can be completed. When verifying, the certificate information is the long-term certificate information within UKey.

Sign with UKey certificate+seal: When both the seal and certificate exist in the UKey device, users do not need to apply for the seal again in the contract lock, and can directly use the seal and certificate in UKey to complete document signing. When signing, the user holding the UKey pulls the seal into the original text. When completing the signing, the UKey's PIN code needs to be verified. After verification, the signing can be completed. When verifying the signature, the seal image and certificate information are both relevant information within UKey.
