I am very grateful to the author: Li Suke was actually looking for materials, the main unsolved problem is how to obtain the privatekey in the keystore file. You can check the jsdk 1.4 API documentation, but I did not find this method after reading it twice from top to bottom: load ().......) Certificat
Knowledge points of iOS Certificate Signature and knowledge points of ios Certificate Signature I interviewed a lot of iOS development engineers before, but the project is still good, but when talking about certificates and signatures, few of them can be said first. As an iOS development engineer, whenever you are bus

Solution: "The list signature certificate cannot be found in the certificate store" This problem seems to have been encountered before, but it is hard to remember. ProgramRegenerate with the following error message:The list signature certificate cannot be found in the
CA certificates are widely used in digital signatures, and because Windows supports RSA algorithms well, many third-party applications under the Windows platform support the application of cryptography for RSA algorithm certificates. Recently, the opportunity to take advantage of project summary, especially in Windows under the common CA Certificate digital signature
Often change machines to systems. If a project is replaced with machines and then rebuilt, the following errors may occur:"Unable to find manifest signing Certificate in the certificate store" Solution: 1. In the project properties-> signing option (Signature)-> sign the clickonce manifests (for the clickonce signature
Encryption and decryption use the same key algorithm, called symmetric encryption algorithm. encryption and decryption use different keys, called asymmetric encryption algorithms. The public key system is an asymmetric encryption algorithm. For symmetric encryption, symmetric keys must be protected. For public key algorithms, private keys must be protected.Public
Preface First look at Baidu Encyclopedia of Digital Signatures and digital certificate interpretation: Digital Signature: A fixed-digit message digest is computed by the hash algorithm agreed by both parties. Mathematically guaranteed: As long as any one of the changes in the message, the recalculated report digest to the value will not match the original value.
