如何使用 DocuSign 生成的公钥和私钥生成 .jks 文件

Question

I have public key & private key with me. These keys are generated by the DocuSign backend itself. Now I need to generate the .jks file out of it to use in my application. I only have a public key & a private key. I don't have any certificate provided by DocuSign. I tried a lot using commands like:

1. openssl req -x509 -sha256 -nodes -days 1000 -newkey rsa:2048 -keyout kmat_wmio.key -out kmat_wmio.crt (generates private and public key pair)

2. openssl pkcs12 -export -in kmat_wmio.crt -inkey kmat_wmio.key -out kmat_wmio.p12 (Keystore in PKCS12 format)

3. keytool -importkeystore -srckeystore kmat_wmio.p12 -srcstoretype PKCS12 -destkeystore kmat_wmio.jks -deststoretype JKS (Keystore in JKS format)

But these commands didn't help much. They generate the new public & private key. But I need to generate the .jks file with the existing public & private key. Please suggest the suitable guideline or correct commands for the same.

Answer 1

Now i need to generate the .jks file out of it, to use in my application.

I'm not clear why you need this. The private key is used for JWT Authentication and is a text file format. You don't need another file, you can use it as-is with Java to make API calls using JWT. I would suggest you use the Java package (SDK) that has built-in wrappers that just take the private key and a few other pieces of information and get you an access token to make API calls.

Easier still would be to download theJava quickstart which includes all the code you need to make eSign API calls with DocuSign using Java.
