PHP, C #, and JAVARSA signatures and signatures are found on the Internet. To make a contribution, we must repost and express our gratitude to Zhuo Ermei for her selfless dedication. 1) the signature algorithm uses SHA1withRSA. 2) the signed data bit base64 encoded ciphertext string. 3) the formats of private keys signed in the three environments are different. openssl is required for conversion. ----------------------------------- PHP, C # and JAVARSA signatures and signatures This feature h

Mail and email service (III): POP3 authentication mechanism and relay rules We use Mago's "Create an existing Mail System based on the virtual user's mail system architecture" to implement the POP3 authentication mechanism. If you do not have an email service system that can be used, you can follow the instructions provided by magio and proceed step by step. I believe you can do this. Enter the subject: POP3 authentication mechanism: 1. Create a CA Service to prepare for certificate issuance # C

In the process of developing or using SSL, a lot of software needs us to provide Java KeyStore, especially some Java-based middleware products.Our usual practice is that the JDK comes with a tool command (Keytool) to do, for example, the following exampleKeytool-import-v-alias entrust2048-file D:\certs\EnTrust2048.cer-keystore D:\certs\test.jksKeytool-import-v-alias Entrustcertificationauthorityl1c-file D:\
