Working on a java project and I want to get access tokens with usernames and passwords.
But for the access tokens I need the consumer_key and the consumer_secret.
I already created my application at Twitter Apps and have a access token for my own account.
Im using the library Twitter 4J.
You can generate these keys on the "Keys and Access Tokens" tab of your app.
Consumer Key (API Key) and Consumer Secret (API Secret) are in the key and access tokens tab in your application , if there is no key in your application setting, you should first "generate consumer key and secret".

In Payment Intent API (https://stripe.com/docs/api/payment_intents/object) ,
Many of the places it is written "RETRIEVABLE WITH PUBLISHABLE KEY" fo ex- id, currency, payment_method, what does it mean?
Whether it means that we can retrieve these value when we integrating the client SDK?
The publishable key is used in your client-side code
https://stripe.com/docs/keys#:~:text=On%20the%20client%2Dside.%20Can%20be%20publicly%2Daccessible%20in%20your%20web%20or%20mobile%20app%E2%80%99s%20client%2Dside%20code
So yes, when using Stripe SDK on your client-side using the publishable key (pk_xxx) you can retrieve only the fields that mention “retrievable with publishable key” in the doc.
If you use your secret key (sk_xxx) to retrieve a PaymentIntent, you will get access to all its properties.
Also, if you want to create a PaymentIntent you must use the secret key in your backend.
Server side, i'm creating a custom tokens using a third-party JWT library
I'm using the private key token from the service account JSON file to sign the JWT.
I want to verify the token with the public keys provided by firebase (that we also find in the account JSON file)
My question is that firebase is providing public certificate like these exemples. I'm having problems using them since the jwt.io is always displaying 'not Verified'.
NB: I'm using Java in the backend and i don't want to use firebase service account ID.
I have a Spring-Boot application with MongoDB. I want to register the client using OAuth2.0 strategy and store client-id and client secret key in database. I am able to generate the access token by using some dummy client and secret key from the below url: http://websystique.com/spring-security/secure-spring-rest-api-using-oauth2/
I want to know how to generate the client id and secret key in my java code. Any help is appreciated.
Client ID and secret are generated by service providers to let the developers register their application and access their API's.
There are many ways of generating Client_id and Client secret.It depends on your choice.
Client_id is a public identifier for apps.It should be unique and not easily guessable . So you could use like a 32-character hex string , Guid , Guid + systemTime ,also you can hash it , encrypt it or anything else you want to make it unique identifier. (you would find java code easily for the same)
Client_secret is a secret known only to the application and the
authorization server.So you could use a cryptographically-secure library to generate a 256-bit value and converting it to a hexadecimal representation.
You should avoid using common UUID libraries.
Also you should not store the secret in plain text, instead only store an encrypted or hashed version, to help reduce the likelihood of the secret leaking.
Here are some examples of client ID from services that support Oauth:

I'm trying to send an https request to a server using Java. The URL to which I'm connecting needs the clientkey.
The URL is: "https://www.zipcodeapi.com/rest/"+clientKey+"/info.json/" + zipcode + "/radians";
How would I get the client key?
I think so you need to register on this website to generate a client key , basically these keys are like an access token to the web services you want to consume.
You can register but as the website says "free account allows up to 50 API requests per hour. Complete this form to get an API key to start using the API"

I am trying to authenticate a java app to AWS services using a developer-authenticated Cognito identity. This is very straightforward in the AWS mobile SDKs (documentation), but I can't seem to find the equivalent classes in the Java SDK.
The main issue I am having is that the Java SDK classes (such as WebIdentityFederationSessionCredentialsProvider) require the client code to know the arn of the role being assumed. With the mobile SDK, it uses the role configured for the federated identity. That's what I'd prefer to do, but it seems the Java SDK doesn't have the supporting classes for that.
The last comment from Jeff led me to the answer. Thanks Jeff!
String cognitoIdentityId = "your user's identity id";
String openIdToken = "open id token for the user created on backend";
Map<String,String> logins = new HashMap<>();
logins.put("cognito-identity.amazonaws.com", openIdToken);
GetCredentialsForIdentityRequest getCredentialsRequest =
new GetCredentialsForIdentityRequest()
.withIdentityId(cognitoIdentityId)
.withLogins(logins);
AmazonCognitoIdentityClient cognitoIdentityClient = new AmazonCognitoIdentityClient();
GetCredentialsForIdentityResult getCredentialsResult = cognitoIdentityClient.getCredentialsForIdentity(getCredentialsRequest);
Credentials credentials = getCredentialsResult.getCredentials();
AWSSessionCredentials sessionCredentials = new BasicSessionCredentials(
credentials.getAccessKeyId(),
credentials.getSecretKey(),
credentials.getSessionToken()
);
AmazonS3Client s3Client = new AmazonS3Client(sessionCredentials);
...
If that's the route you want to go, you can find this role in the IAM console, named Cognito_(Auth|Unauth)_DefaultRole. These are what Cognito generated and linked to your pool, and you can get the ARN from there.
This blog post may be of some assistance. All of the APIs the SDK uses to communicate with Cognito to get credentials are exposed in the Java SDK, you just need to use your own back end to get the token itself. Once you have it, you can set the logins the same way you normally would with another provider and it'll all work.
