Instance Method Details

#to_spki(format = :uncompressed) ⇒ OpenSSL::X509::SPKI

Generate an OpenSSL::X509::SPKI structure for this public key.

Parameters:

  • format (Symbol) (defaults to: :uncompressed) —

    whether to return the SPKI containing the compressed or uncompressed form of the curve point which represents the public key. Note that from a functional perspective, the two forms are identical, but they will produce completely different key and SPKI fingerprints, which may be important.

Returns:
