系统与系统的数据交互中,有些敏感数据是不能直接明文传输的,所以在发送数据之前要进行加密,在接收到数据时进行解密处理;然而由于系统与系统之间的开发语言不同。

本次需求是生成二维码是通过java生成,由php来解密。基于这类需求所以选择了RSA进行加解密。

生成RSA公私钥分成三步生成RSA公私钥,第1、2步可以满足php的使用,由于java的私钥要转化为PKCS8格式才能使用,所以执行第3步来实现。

还有一种加密方式参考: DES ECB 模式 JAVA PHP C# 实现 加密 解密 兼容 。

 

1、生成私钥

openssl genrsa -out rsa_private_key.pem 1024 

如下:

-----BEGIN RSA PRIVATE KEY-----
MIICXQIBAAKBgQC6BSDlbRplhMMNZBKHX4xe8AwESpzHVfAcHHsX9FFSMuF91W3c

QDhaWHgFA+8lED+bWTvJxt/IMmzyYBaGnZbEjCECKZLD
-----END RSA PRIVATE KEY-----

 

2、生成公钥

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

如下:

-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC6BSDlbRplhMMNZBKHX4xe8AwE
SpzHVfAcHHsX9FFSMuF91W3cxgT/g5n+qlLLFzCE3hWG/yX5NMAxR4mS3MlhyXKw

qvOw3G9leClSvjVnSwIDAQAB
-----END PUBLIC KEY-----

 

3、将RSA私钥转换成PKCS8格式

openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt

如下:

-----BEGIN PRIVATE KEY-----
MIICdwIBADANBgkqhkiG9w0BAQEFAASCAmEwggJdAgEAAoGBALoFIOVtGmWEww1k
