## Detailed Description

asymetric ciphering

Definition at line 50 of file crypto_asym.hpp.

## Constructor & Destructor Documentation

## crypto_asym()

libdar::crypto_asym::crypto_asym | ( | const std::shared_ptr< user_interaction > & | ui | ) |

inline

general use constructor

Definition at line 55 of file crypto_asym.hpp.

## ~crypto_asym()

libdar::crypto_asym::~crypto_asym | ( |  | ) |

inline

the destructor

Definition at line 70 of file crypto_asym.hpp.

## 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.

## release_context()

void libdar::crypto_asym::release_context | ( |  | ) |

inlineprivate

Definition at line 115 of file crypto_asym.hpp.

## 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

Definition at line 93 of file crypto_asym.hpp.
