Member Function Documentation

decrypt()

void libdar::crypto_asym::decrypt	(	generic_file &	ciphered,
		generic_file &	clear
	)

un-cipher data

Parameters

[in]	ciphered	contains the encrypted data to decipher
[out]	clear	resulting un-ciphered (thus clear) data (the object must be readable)

Note

this assumes the GnuPG keyring has an appropriated private key (the objet must be writable)

encrypt()

void libdar::crypto_asym::encrypt	(	const std::vector< std::string > &	recipients_email,
		generic_file &	clear,
		generic_file &	ciphered
	)

encrypt (and sign if signatures have been given using set_signatories) data for the given recipients

Parameters

[in]	recipients_email	list of email or keyid of recipient that will be able to read the encrypted data
[in]	clear	where to read from clear data to be encrypted (the object must be readable)
[out]	ciphered	where to write down encrypted data (the object must be writable)

Note

this assumes the GnuPG keyring has the public keys of the recipient listed

get_ui()

user_interaction& libdar::crypto_asym::get_ui ( ) const

inline

exposing to public visibility the protected method of mem_ui

used to provide access to the user_interaction from the callback function required by gpgme_set_passphrase_cb().

Definition at line 99 of file crypto_asym.hpp.

References libdar::mem_ui::get_ui().

verify()

const std::list<signator>& libdar::crypto_asym::verify ( ) const

inline

after un-ciphering data retrieve the list of signature that were used beside encryption return a sorted list of signatories
