狗日的支付宝

 

用openssl 生成的密钥老是报以下错误：

java.security.spec.InvalidKeySpecException: java.security.InvalidKeyException: IOException : DER input, Integer tag error

后来发现，原来是支付宝，生成的命令有问题，参数放错位置，害死人。

 

 

 

 将(3) 的命令改为：

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

 

完整命令：

1.

openssl genrsa -out rsa_private_key.pem 1024

2.

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

 

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