It is mainly used for outputting certificate information , can also sign certificate request file, self-signed, convert certificate format , etc.The OpenSSL x509 tool does not use the settings in the OpenSSL configuration file, but is completely self-setting or uses the default value of the pseudo-command, which is like a complete small CA toolbox .[-caserial filename] [-text] [-MD2|-MD5|-SHA1|-MDC2] [-extfile filename] [-extensions section]There are

certificate is typically requested from the CA center, the encryption certificate and the RSA encryption private key are returned as a file in PFX format.Below, for these three types of certificate files, using OpenSSL to decode, get the corresponding X509 struct pointer. Note that the contents of the certificate file in the sample code refer to binary data, and

/or issuer name may be used repeatedly after a period of time, the x509-2 (X509) Certificate consists of two keys, usually called key pair, public key encryption, private Key decryption. Today, I want to give an in-depth introduction and understanding of X509, because X509 C

Research on creating an X509 Certificate and obtaining the certificate key Author: Xiao Bo Personal blog: http://blog.csdn.net/eaglet; http://www.cnblogs.com/eaglet 2007/7 Nanjing Background The format of the server SSL digital certificate and the client unit digital certificate complies with the X.509 standard. X.509 is a digital certificate standard developed by the ITU (ITU-T. In order to provide public network user directory information services,

In the previous article, "CSP: Using CryptoAPI to decode X509 certificate content," describes how to use CryptoAPI to decode the certificate file to get the pccert_context method of the certificate context handle. Let's go on to get the desired certificate entry through the certificate context handle. This article first describes how to get the base entry for a certificate, and later an article explains how to obtain an extension of the certificate.Th

unsecured network to prevent hackers from eavesdropping and attacking. SSL (Secure Sockets Layer) can be used to encrypt the flow of data between the Web server and the client. SSL encrypts data using asymmetric cryptographic techniques. The encryption process uses two keys: a public key and a corresponding private key. Data encrypted with the public key can only be decrypted with the corresponding private key, and the data encr

Please pay attention to the previous series of articlesDecode X509 certificate content using CryptoAPIParsing X509 Certificate Primitives using CryptoAPIThrough the previous article, we can use CryptoAPI to decode the X509 certificate file and parse the basic key of the certificate, this time we try to get the hash value of the certificate through CryptoAPI . The

X509 Certificate IntroductionThe digital certificate standard developed by the International Telecommunication Union (ITU-T), which I believe is well known, is now available in three versions, as far as I know, the. NET uses the concept of the X.509-2,x.509-2 version to introduce the principal and issuer unique identifiers to resolve the subject and/ or the issuer name may be reused after a certain period of time, the

Read into a CER file, CertCreateCertificateContext generate Cert_context. Cert_context there is a cert_info,cert_info in this data structure that has a subjectpublickeyinfo, Subjectpublickeyinfo is a data segment of the Publickey_info type , which holds the ID of the algorithm and the DER encoded public key. With this der Code, we can use other tools (such as OpenSSL) to parse the parameters of the public key. Unfortunately, the interfaces defined by CryptoAPI cannot handle DER encoding directly

In Internet-based WCF services, security is a very important part. There are many security modes in WCF. This time, we will consider using a limited server environment (such as a virtual host) to configure the message security mode for X509 Certificate authentication. Generally, in this extreme environment, it is difficult to implement SSL-based transmission security. Therefore, we consider deploying message security and
