4、PKCS#8编码:指明输入私钥文件为rsa_private_key.pem,输出私钥文件为pkcs8_rsa_private_key.pem,不采用任何二次加密(-nocrypt) 1 openssl pkcs8 -topk8 -in rsa_private_key.pem -out pkcs8_rsa_private_key.pem -nocrypt 至此:可用的密钥对已经生成好了,私钥使用pkcs8_rsa_private_key.pem,公钥采用rs...
pkcs#1 格式的 Key 无法用 openssl asn1parse 命令读取,我们应该把它转换成更通用的 pkcs#8 格式的 Key $ cp icapass.enc icapass-pkcs8.enc $ openssl pkcs8 -topk8 -in FactTrust_RSA_ICA1.key -out FactTrust_RSA_ICA1-PKCS8.key -passin file:icapass.enc -passout file:icapass-pkcs8.enc ...

Step1. Create private/public keypair (optional) openssl genrsa -out private.pem 1024 >private.pem 1. This creates a key file called private.pem. This file actually have both the private and public keys, so you should extract the public one from this file: ...

用RandKey进行AES256进行加密核心数据。非对称加密效率低,加密内容短。所以要用aes这样的对称加密来加密data部数据。 核心代码 参考了XPorter的文章和其他几篇类似文章。 #pragmamark ---生成密钥对+(BOOL)generateRSAKeyPairWithKeySize:(int)keySize publicKey:(RSA**)publicKey privateKey:(RSA**)privateKey{if...
1.使用openssl生成RSA私钥及证书 生成RSA 私钥和自签名证书,命令如下: 1 openssl req -newkey rsa:2048-nodes -keyout rsa_private.pem -x509 -days365-out cert.crt req是证书请求的子命令,-newkey rsa:2048 -keyout rsa_private.pem 表示生成私钥(PKCS8格式),-nodes 表示私钥不加密,若不带参数将提示输入...
