Detailed instructions

1. Select the key format from the dropdown that matches the service or pattern you need (Stripe, AWS, GitHub, generic, etc.).
2. Set the count field to the number of fake keys you want — use 1 for a single example or more for batch fixture seeding.
3. Click Generate to produce the keys and review the output list for format correctness.
4. Copy individual keys by clicking them, or select all output text to paste the full batch into your file or editor.

Use Cases

• •Populate a README's .env.example with a Stripe-style sk_live_ placeholder that looks production-realistic
• •Seed a Postgres fixture file with 20 fake AWS-style access keys to load-test an IAM validation service
• •Exercise authentication middleware in Jest or Supertest without storing real credentials in the test suite
• •Paste a GitHub-style token into an OpenAPI securitySchemes example so generated SDK clients can run demo requests
• •Replace real keys in Postman collections before sharing them with a client or publishing to a public workspace

Tips

• →For Stripe, use the 'sk_test_' format in documentation rather than 'sk_live_' — readers recognize it as a test credential and are less likely to question its validity.
• →When seeding a test database, generate slightly more keys than you need and discard duplicates — random generation can occasionally repeat short segments.
• →Pair a fake AWS access key with a separately generated fake secret key (a longer random string) to make your example env files feel complete and realistic.
• →If your CI pipeline's secret scanner flags fake keys, add an inline ignore comment specific to your scanner (e.g., `# noqa: secret`) rather than disabling the rule globally.
• →For blog posts and tutorials, use the same fake key consistently throughout the article — switching keys mid-tutorial confuses readers following along step by step.
• →Test both your happy path and your error path: use a correctly formatted fake key to test format validation passing, then deliberately malform it to verify your rejection logic fires.
