Crate uselesskey_core_token_shape 

Token shape generation primitives for test fixtures.

Generates realistic-looking API keys, bearer tokens, and OAuth access tokens from deterministic seed material.

Examples

use uselesskey_core_token_shape::{generate_token, TokenKind, authorization_scheme};
use uselesskey_core_seed::Seed;

let seed = Seed::new([42u8; 32]);

// Generate an API key (prefixed with `uk_test_`)
let api_key = generate_token("my-service", TokenKind::ApiKey, seed);
assert!(api_key.starts_with("uk_test_"));

// Generate a bearer token (base64url-encoded random bytes)
let bearer = generate_token("my-service", TokenKind::Bearer, seed);
assert_eq!(authorization_scheme(TokenKind::Bearer), "Bearer");

// Generate an OAuth access token (JWT-shaped: header.payload.signature)
let oauth = generate_token("my-service", TokenKind::OAuthAccessToken, seed);
assert_eq!(oauth.matches('.').count(), 2);

Enums

TokenKind

Token shape kind. Specification for token fixture generation.

Constants

API_KEY_PREFIX

Prefix used for API-key token fixtures.

API_KEY_RANDOM_LEN

Number of random base62 characters used in API-key fixtures.

BEARER_RANDOM_BYTES

Number of raw random bytes in opaque bearer tokens.

OAUTH_JTI_BYTES

Number of random bytes used for OAuth jti.

OAUTH_SIGNATURE_BYTES

Number of random bytes used for OAuth signature-like segment.

Functions

authorization_scheme

Return HTTP authorization scheme for the token kind.

generate_api_key

Generate an API-key style token fixture (uk_test_<base62>).

generate_bearer_token

Generate an opaque bearer token fixture (base64url of 32 random bytes).

generate_oauth_access_token

Generate an OAuth access token fixture in JWT shape (header.payload.signature).

generate_token

Generate a token value for the provided shape kind.

random_base62

Generate a deterministic base62 string from the provided seed.
