If the signing device does not support the hash algorithm, the solution will send the registry key according to the instructions on this page? aSignHash？ Set to? SHA 1. However, this method is not recommended.
Because this may set SHA 1 as the default hash algorithm for all signatures, this method is not recommended by the whole industry. Therefore, Adobe strongly recommends consulting the manufacturer of your signature device or driver for support of SHA256 or later.
New hash device or driver.
Solution:
Use this computer (remember not to remotely connect to another computer for operation) to install the software required for online banking. Then plug the U shield into the computer and install all the signature software provided by the bank.
For example, "CCB industrial and commercial registration certification", running this software signature on the desktop instead of using adobe acrobat or adobe reader will not succeed.
An encryption service provider is a program that performs authentication, encoding, and encryption services. Windows-based applications access the program through the Microsoft encrypted application programming interface.
When an application with a new certificate is generated, the information in the application is first sent from the application to CryptoAPI. CryptoAPI provides correct data to CSP installed on computers or computer-accessible devices.
