Class Method Details

.parse ⇒ PublicKey

Parses a PGP public key from a given string input.

Parameters:

  • input (String) —

    the PGP public key in string format.

Returns:

  • (PublicKey) —

    an instance of PublicKey if parsing is successful.

Instance Method Details

#algorithm ⇒ Integer

Returns the algorithm used by the public key.

Returns:

  • (Integer) —

    the algorithm identifier.




# File 'lib/pgp.rb', line 60

#algorithm_name ⇒ String

Fetches the name of the algorithm used by the public key from a predefined list of names.

Returns:

  • (String) —

    the name of the algorithm.

def algorithm_name
  KEY_ALGORITHM_NAMES.fetch(algorithm, 'Unknown')
end

#created_at ⇒ Time

Returns the creation time of the public key.

Returns:

  • (Time) —

    the creation time of the public key.

#encrypt(data, algorithm = ENCRYPTION_ALGORITHM_AES_128) ⇒ String

Encrypts data using the specified encryption algorithm.

Parameters:

  • data (String) —

    the data to be encrypted.

  • algorithm (Integer) (defaults to: ENCRYPTION_ALGORITHM_AES_128) —

    the encryption algorithm to use, defaults to AES-128.

Returns:

  • (String) —

    the encrypted data encoded by base64.

def encrypt(data, algorithm = ENCRYPTION_ALGORITHM_AES_128)
  encrypt_with_algorithm(data, algorithm)
end

#encrypt_with_algorithm(input, algorithm) ⇒ String

Encrypts data with the specified algorithm.

Parameters:

  • input (String) —

    the data to be encrypted.

  • algorithm (Integer) —

    the encryption algorithm identifier.

Returns:

  • (String) —

    the encrypted data encoded by base64.

#encryption_supported? ⇒ Boolean

Checks if the public key supports encryption.

Returns:

  • (Boolean) —

    true if the key supports encryption, false otherwise.




# File 'lib/pgp.rb', line 68

#expired? ⇒ Boolean

Checks whether the public key has expired.

Returns:

  • (Boolean) —

    true if the key has expired, false otherwise.

  expires_at.to_i <= Time.now.to_i
end

#expires_at ⇒ Time?

Returns the expiration time of the public key, if any.

Returns:

  • (Time, nil) —

    the expiration time of the public key or nil if it does not expire.




# File 'lib/pgp.rb', line 80

#fingerprint ⇒ String

Returns the fingerprint of the public key.

Returns:

  • (String) —

    the fingerprint of the public key.




# File 'lib/pgp.rb', line 56

#inspect ⇒ String

Returns a string representation of the PublicKey object, including its fingerprint, algorithm name, and version.

Returns:

  • (String) —

    the string representation of the PublicKey object.

def inspect
  "#<#{self.class} #{fingerprint} #{algorithm_name} v#{version}>"
end

#signing_supported? ⇒ Boolean

Checks if the public key supports signing.

Returns:

  • (Boolean) —

    true if the key supports signing, false otherwise.




# File 'lib/pgp.rb', line 64

#version ⇒ Integer

Returns the version of the public key.

Returns:

  • (Integer) —

    the version of the public key.
