Options

  • --std and --reverse-std will output both key and certificate to STDOUT instead of writing files.

  • --double-std will output the key to STDERR and the certificate to STDOUT instead, so redirection can be used to write or pipe files where needed efficiently. Take care of checking the key is actually formatted properly and not an error message though!

  • --inspect outputs terse information about the passed certificate file (or url) and exits.

  • --make-ca creates a key/certificate pair suitable for issuing instead. Use with --ca.

  • --ca NAME signs a certificate with a CA pair instead of self-signing. Provide only the common filename, without the .crt and .key extensions.

  • --client creates client certificates rather than server ones.

  • --ecdsa creates p256r1 ECDSA certificates (default).

  • --ed25519 creates ED25519 certificates.

  • --rsa creates 4096-bit RSA certificates (not for production use).

See the man page for more.
