To get a JSON Web Token (JWT) from an Ory session cookie, you can follow these steps: 1. First, you need to create a JSON Web Key set and store it locally. You can do this using the following command:

bash ory create jwk some-example-set \     --alg ES256 --project {project.id} --format json-pretty \     > es256.jwks.json

jsonnet local claims = std.extVar('claims');   local session = std.extVar('session');      {     claims: {       iss: claims.iss + "/additional-component",       schema_id: session.identity.schema_id,       session: session,     }   }

bash JWKS_B64_ENCODED=$(cat es256.jwks.json | base64)   JSONNET_B64_ENCODED=$(cat claims.jsonnet | base64)

bash ory patch identity-config {project.id} \     --add '/session/whoami/tokenizer/templates/jwt_example_template1={"jwks_url":"base64://'$JWKS_B64_ENCODED'","claims_mapper_url":"base64://'$JSONNET_B64_ENCODED'","ttl":"10m"}' \     --format yaml

javascript import { Configuration, FrontendApi } from "@ory/client"      const frontend = new FrontendApi(     new Configuration({       basePath: `https://${process.env.ORY_PROJECT_SLUG}.<http://projects.oryapis.com|projects.oryapis.com>`,     }),   )      export async function toSessionWithJwt(sessionId: string) {     const session = await frontend.toSession({       tokenize_as: "jwt_example_template1",     })     const jwt = session.tokenized     return jwt   }

[Source](https://www.ory.sh/docs/identities/session-to-jwt-cors#end-to-end-example) Please replace

{project.id}

and

{project.slug}

with your actual project ID and slug. Also, replace

sessionId

with the actual session ID you want to convert to a JWT.
