Overview

Instance Attribute Summary (collapse)

• - (Object) san_names readonly

  Returns the value of attribute san_names.

• - (Object) spki readonly

  Returns the value of attribute spki.

• - (Object) subject readonly

  Returns the value of attribute subject.

Instance Method Summary (collapse)

• - (Integer) bit_strength

  Returns the bit strength of the key used to create the SPKI.

• - (Boolean) dsa?

  Returns whether the public key is DSA.

• - (Spki) initialize(opts = {}) constructor

  you can also pass OIDs (see tests).

• - (String) key_algorithm

  Returns key algorithm (RSA/DSA).

• - (OpenSSL::PKey::RSA) public_key

  Public key.

• - (Boolean) rsa?

  Returns whether the public key is RSA.

• - (String) to_der

  Converts the SPKI into the DER format.

• - (Hash) to_hash

  Returns a hash structure you can pass to the Ca You will want to call this method if you intend to alter the values and then pass them to the Ca class.

• - (String) to_pem (also: #to_s)

  Converts the SPKI into the PEM format.

• - (Object) write_der(filename_or_io)

  Writes the SPKI into the DER format.

• - (Object) write_pem(filename_or_io)

  Writes the SPKI into the PEM format.
