RSA加密 iOS以及java

由于iOS代码环境和java的差异，在生成rsa密钥对时，各自需要的文件格式差异较大。

#!/usr/bin/env bash

echo "Generating RSA key pair ..."

echo "1024 RSA key: private_key.pem"

openssl genrsa -out private_key.pem 1024

echo "create certification require file: rsaCertReq.csr"

openssl req -new -key private_key.pem -out rsaCertReq.csr

echo "create certification using x509: rsaCert.crt"

openssl x509 -req -days 3650 -in rsaCertReq.csr -signkey private_key.pem -out rsaCert.crt

echo "create public_key.der For IOS"

openssl x509 -outform der -in rsaCert.crt -out public_key.der

echo "create private_key.p12 For IOS. Please remember your password. The password will be used in iOS."

openssl pkcs12 -export -out private_key.p12 -inkey private_key.pem -in rsaCert.crt

echo "create rsa_public_key.pem For Java"

openssl rsa -in private_key.pem -out rsa_public_key.pem -pubout

echo "create pkcs8_private_key.pem For Java"

openssl pkcs8 -topk8 -in private_key.pem -out pkcs8_private_key.pem -nocrypt

echo "finished."

// 将公钥进行base64编码

openssl x509 -inform der -in public_key.der -out public_key_base64_2.pem

openssl x509 -outform der -in public_key_base64_2.pem -out public_key_base64.cer
