1. Do you want to play or do you want to do it yourself? It's not recommended to play. After all, such mining software is cloud miner, and they also dig tokens issued by them privately. It's very possible to earn money and run. If you want to do it yourself, you can go to the company for on-site investigation. After all, this also involves some block chain technology
2. The official way of purchase will be announced, including player cloud, extreme route, Xiaomi and 360. At present, I am paying attention to the recent jCG K3 blockchain route. Compared with the playing method of digital currency, the revenue of shared CDN business is stable, which is linked to the broadband upload speed, and mining is converted into currency. Compared with the old mining area, mining in the new mining area will be much easier, mainly because of the old brand and high reliability. But we also need to consider the risk, it depends on indivial decision-making.
3. Before I tell you the scope of application, I'll talk about the function of digital signature: digital signature uses the private key of digital certificate to encrypt the abstract of data, so as to ensure the integrity, authenticity and non repudiation of data
digital signature is the most reliable and key method to ensure the integrity, authenticity and non repudiation of data. Where it is needed, it can be applied
now the typical applications are: online banking, e-commerce, e-government, network communication, etc

4. F18 carrier based aircraft simulation take-off and landing 2 you can download to play, this game is still very fun, you can go directly to the app search, there are a lot of resources on this, and are certified by security, but also a key root mobile phone, the success rate is very high, there are a lot of mobile phones to support, hope to help you oh
5. Tools to prepare: makecert.exe, cert2spc.exe, pvk2pfx.exe, signtool.exe
there is a certificate generation tool makecert.exe in MS sdk6.0. You can use this tool to generate test certificates
in the first step, a self signed root certificate (issuer) is generated< br />> makecert -n " CN=Root" - R - SV rootissuer.pvk rootissuer.cer
at this time, a prompt box will pop up. First, set the private key protection password for the rootissuer.pvk file
then, enter the password again and use the private key (in the rootissuer.pvk file) to encrypt the public key (in the rootissuer.cer file)
the second step is to use this certificate to issue a sub Certificate (subject)< br />> makecert -n " CN=Child" - IV rootissuer.pvk - IC rootissuer.cer - SV childsubject.pvk childsubject.cer
in this case, a prompt box will pop up to set the protection password for the private key file childsubject.pvk of this sub certificate
then, enter the password of the private key (in childsubject. PVK) of the sub certificate to protect the public key of the sub Certificate (in childsubject. CER)
next, you will be prompted to enter the password of the private key of the root certificate (in rootissuer. PVK) to sign the whole sub Certificate (public key and user information)
if you want to issue more sub certificates, similarly, you can use this certificate to issue further certificates, provided that the childsubject certificate can also be used for issuing (as an issuer)
remarks:
(1) if you need an interactive certificate for secure communication, add the option sky exchange
(2) if you need a signing certificate to sign certificates or binary files, then add the option sky signature.
(3) if you need a client certificate to mark your identity or personal information protection (e-mail), then the E field in option - n is indispensable
examples: - N & quot; CN = company name, e = e-mail address, o = organization name, Ou = organization unit, C = country, s = province (state), P = County & quot< Other auxiliary tools:
1) public key certificate format is converted to SPC. cert2spc.exe
> Cert2spc testroot. Cer testroot. SPC
. SPC means software publisher certificate.
2) combines the public key certificate and the private key into a PFX format certificate file. pvk2pfx.exe
> Pvk2pfx - PVK testroot.pvk - SPC testroot.spc - PFX testroot.pfx
enter the protection password of testroot.pvk to merge. PVK and. SPC files. If you do not set the protection password of testroot.pfx to be merged, the protection password is the same as that of the input file testroot.pvk Note: it's OK to get the CER file directly, but it's not necessary to get the SPC file).
3) signature tool. Signature.exe
binary file digital signature. In order to ensure the integrity of binary file, digital signature is a good method
the following command starts a file signing tool wizard with graphical interface:
& gt; Signtool wizard
the following is the command line signature:
& gt; signtool sign /f " Full path of PFX file & quot/ p " Protection password of PFX file & quot/ t " http://timestamp.verisign.com/scripts/timstamp.dll" / d " Description of this signature & quot& quot; The whole path of the signed program & quot;

7. First of all, this hash change and digital signature is to record this transaction and publish it to the whole network. Then the previous transaction here is the previous transaction record of your transaction, because this is a distributed ledger, that is to say, everyone's transaction is well documented in this ledger
8. Digital signature is a typical application of asymmetric encryption algorithm. The application process of digital signature is that the sender of data source uses its own private key to encrypt the data checksums or other variables related to the data content to complete the legal "signature" of the data. The receiver of data uses the public key of the other party to interpret the received "digital signature", and uses the interpretation results to test the integrity of the data, To confirm the validity of the signature. Digital signature technology is an important technology to confirm the identity in the virtual environment of network system. It can completely replace the "autograph" in the real process, which is guaranteed technically and legally. In digital signature applications, the sender's public key can be easily obtained, but his private key needs to be strictly confidential.
