Jira OAuth - unable to create application link

Question

I am trying to create an application that uses jira for authentication. I am using the Jira Rest API for the same. The documentation says that to create a link to the application, the same public key and consumer key are used as in the document. This works fine and I can create an access token. But in the Java code, as mentioned in this , I'm not sure what should be given for private_key. I tried two methods-

1. Generated a random private key using rsa and provided it instead of private_key, which did not work. This gave an exception talking about length too long . I tried on 2048, 1024, 512, 256 and 128 bits. Everything gave the same error.

Application Link:

Consumer Key: Hard Coded Consumer

Consumer Name: hard-consumer

Public Key: MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxZDzGUGk6rElyPm0iOua0lWg84nOlhQN1gmTFTIu5WFyQFHZF6OA4HX7xATttQZ6N21yKMakuNdRvEudyN / coUqe89r3Ae + rkEIn4tCxGpJWX205xVF3Cgsn8ICj6dLUFQPiWXouoZ7HG0sPKhCLXXOvUXmekivtyx4bxVFD9Zy4SQ7IHTx0V0pZYGc6r1gF0LqRmGVQDaQSbivigH4mlVwoAO9Tfccf + V00hYuSvntU + B1ZygMw2rAFLezJmnftTxPuehqWu9xS5NVsPsWgBL7LOi3oY8lhzOYjbMKDWM6zUtpOmWJA52cVJW6zwxCxE28 / 592IARxlJcq14tjwYwIDAQAB

2. Generated a pair of private and public keys and provided the same in the application link and in the code, respectively. But in this case, I cannot create an access token. This gives -

Application Link:

Consumer Key: Hard Coded Consumer

Consumer Name: hard-consumer

Public Key: MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC0YjCwIfYoprq / FQO6lb3asXrx LlJFuCvtinTF5p0GxvQGu5O3gYytUvtC2JlYzypSRjVxwxrsuRcP3e641SdASwfr mzyvIgP08N4S0IFzEURkV1wp / IpH7kH41EtbmUmrXSwfNZsnQRE5SYSOhh + LcK2w yQkdgcMv11l4KoBkcwIDAQAB

Can someone explain to me what should be done? Am I missing something here? And also what is the difference between a shared key, a consumer key, and a public key?

thank you in advance

Answer 1

I somehow fixed the problem using the publication, which is presented in the documentation , and the private key, as indicated in the example

But nevertheless, I was not able to create a link to the application with a public and public key.

Answer 2

The exception is due to the ending of "/" in the base JIRA URL (caused by net.oauth.OAuthProblemException: signature_invalid ).

Correct request:

 java -jar rest-oauth-client-1.0.one-jar.jar requestToken https://jira_base_server_url http://your_redirctedUrl
