首先是服务端(server),要生成证书请求(csr),提交给CA(Certificate Authority),即证书授权中心,获得一张证书。这个证书里面包括了服务端的公钥,CA使用其私钥对服务端的公钥进行加密后得到的签名。 然后是证书授权中心(CA),负责接收证书请求(包含请求主体的主体信息、公钥和签名算法),使用自己的私钥对请求中的信息进行加...
而在iOS 上验证证书,我们可以通过APISecCertificateCreateWithData创建证书对象进行后续的验证操作。注意这个API从一个opaque buffer 创建证书。那么对于X509_STORE_CTX,哪些字段是用于证书验证的呢? structx509_store_ctx_st{/* X509_STORE_CTX */.../* The cert to check */X509*cert;/* chain of X509s - ...

StatusSynopsis This module allows one to (re)generate OpenSSL certificates. It implements a notion of provider (ie. selfsigned, ownca, acme, assertonly, entrust) for your certificate. The assertonly provider is intended for use cases where one is only interested in checking properties of a sup...
openssl check signature algorithm of certificate You can use openssl s_client to check the signature algorithm of a certificate on a given server. With support of sha1 certs having been phased out, it may be necessary to verify that the server certificate is sha256 or greater, especially if ...
Check whether there's a certs subdirectory under OPENSSLDIR. In the previous example, it would be /usr/lib/ssl/certs.If the /usr/lib/ssl/certs exists, and if it contains many individual certificate files (with .crt or .pem extension), there's no need for furt...
