The certificate, asymmetric key, or private key data is invalid.
Note After you install this update, you can create the certificate even though the serial number is greater than 16 bytes. Additionally, you will not receive the error message that's mentioned in the "Symptoms" section. However, the serial number will be truncated to 16 bytes when it's saved into the cert_serial_number column in the sys.certificates catalog view. The truncate action occurs only in catalog view. This means that the certificate still preserves the original length of the serial number.
