Spring / Spring CredHub Interview questions
What are the credential types supported by Spring CredHub?
Spring CredHub models every credential type CredHub itself supports, each with its own request/response classes under org.springframework.credhub.support.*:
| Type | Typical use |
| Value | A single opaque string, like an API key |
| Password | A generated or provided password string |
| User | A username/password pair |
| JSON | An arbitrary JSON object of key/value pairs |
| Certificate | A CA-signed or self-signed TLS certificate and private key |
| SSH | An SSH key pair |
| RSA | An RSA key pair |
Each type has a matching credential class (for example PasswordCredential, CertificateCredential) that plugs into the same generic write()/generate() methods, so one API shape is reused across all seven types.
Which of these is NOT a Spring CredHub credential type?
Which credential type pairs a username with a password?
