odin_token_generator_sign

enum OdinError odin_token_generator_sign(struct OdinTokenGenerator *token_generator,
                                         const char *body,
                                         char *out_token,
                                         uint32_t *out_token_length);

Overview

Signs the provided body using the key ID and access key stored in the token generator to sign the provided body, creating a JSON Web Token (JWT). The EdDSA (Ed25519) algorithm is used for the digital signature.

Parameters

Name	Type	Description
token_generator	struct OdinTokenGenerator *	The token generator handle.
body	const char *	The JSON body to sign (should include uid, rid).
out_token	char *	Buffer to write the JWT token to.
out_token_length	uint32_t *	Input: buffer size, Output: actual token length.

Return Value

Type	Description
OdinError	ODIN_ERROR_SUCCESS on success.

Example

#include <odin.h>
#include <time.h>
// Using a JSON library like cJSON or similar is recommended for creating the body
// Here we assume a valid JSON string "claims"

const char *claims = "{\"uid\": \"user1\", \"rid\": \"room1\", \"aud\": \"gateway\"}";
char token[1024];
uint32_t token_len = sizeof(token);

OdinError err = odin_token_generator_sign(token_generator, claims, token, &token_len);
if (err == ODIN_ERROR_SUCCESS) {
    // token now contains the signed JWT
}
