Installation
|
||||
------------
|
||||
tar xvzf gnupg-x.y.tgz
|
||||
cd gnupg-x.y
|
||||
phpize
|
||||
make
|
||||
make install
|
||||
A documentation how to install a PECL-Extension is available in the PHP-Manual http://www.php.net/manual/en/install.pecl.php
|
||||
|
||||
This extension requires the gpgme library, which is available at http://www.gnupg.org/(en)/download/index.html#gpgme
|
||||
|
||||
|
||||
Notes
|
||||
-----
|
||||
- This extension requires at least PHP 4.3.0
|
||||
To use this extension in an OOP style, PHP 5 is required
|
||||
|
||||
- This is a beta version.
|
||||
Don´t use it on production systems.
|
||||
|
||||
- It is now possible to specify multiple keys.
|
||||
see "addsignkey", "addencryptkey" and "adddecryptkey"
|
||||
|
||||
- Verify can now handle all signature-types
|
||||
|
||||
- Only the Open_PGP protocol is currently supported.
|
||||
This shouldn´t be a problem for the most people.
|
||||
|
||||
- Whenever you provide a key to a method, you should make sure, that your given pattern is unique.
|
||||
Otherwise it could happen, that the wrong key is selected from the keyring.
|
||||
The best would be to provide the fingerprint, whenever needed.
|
||||
|
||||
- The underlying lib checks for the presence of the gpg-agent.
|
||||
If a passphrase is required for an operation, this agent is asked first.
|
||||
To avoid this, clear the enviroment-variable GPG_AGENT_INFO (see http://de3.php.net/manual/en/function.putenv.php)
|
||||
|
||||
- To specify a custom location of you keyring, simply store the path in the enviroment-variable GNUPGHOME
|
||||
This should make it easy, to use this extension with the apache-user.

Methods
|
||||
-------
|
||||
Note: the following explanations are describing the usage of this extension in the OO style, which is only
|
||||
available in PHP 5
|
||||
To use this extension in a procedural style, simply call "gnupg_init", which returns a resource.
|
||||
Pass this resource as the first parameter to each function.
|
||||
In procedural style, all methods gets "gnupg_" prefixed. (setarmor becomes gnupg_setarmor)
|
||||
Example:
|
||||
|
||||
$res = gnupg_init();
|
||||
gnupg_setarmor($res,1);
|
||||
|
||||
|
||||
|
||||
- __construct()
|
||||
sets up a new gnupg object
|
||||
( new gnupg() )
|
||||
|
||||
- resource gnupg_init()
|
||||
sets up a new gnupg object for procedural use and returns a resource identifier
|
||||
|
||||
- bool setarmor(int armor)
|
||||
turn on/off armor mode
|
||||
0 = off
|
||||
>0 = on (default)
|
||||
|
||||
- bool setsignmode(int signmode)
|
||||
sets the mode for signing operations
|
||||
see the SIG_MODE_* constants
|
||||
default is SIG_MODE_CLEAR
|
||||
|
||||
- string geterror(void)
|
||||
returns the last errormessage
|
||||
|
||||
- int getprotocol(void)
|
||||
returns the currently used pgp-protocol.
|
||||
atm only PROTOCOL_OpenPGP is supported
|
||||
|
||||
- array keyinfo(string pattern)
|
||||
returns an array with informations about all keys, that matches the given pattern
|
||||
|
||||
- bool addsignkey(string key [,string passphrase])
|
||||
adds a key for signing.
|
||||
|
||||
- bool addencryptkey(string key)
|
||||
adds a key for encrypting.
|
||||
|
||||
- bool adddecryptkey(string key (,string passphrase])
|
||||
adds a key for decrypting
|
||||
|
||||
- bool clearsignerkeys(void)
|
||||
removes all keys which are set for signing
|
||||
|
||||
- bool clearencryptkeys(void)
|
||||
removes all keys which are set for encryption
|
||||
|
||||
- bool cleardecryptkeys(void)
|
||||
removes all key which are set for decryption
|
||||
|
||||
- string sign(string text)
|
||||
signs the given test with the key, which was set with setsignerkey before
|
||||
and returns the signed text
|
||||
the signmode depends on gnupg_setsignmode
|
||||
|
||||
- string encrypt(string text)
|
||||
encrypts the given text with the key, which was set with setencryptkey before
|
||||
and returns the encrypted text
|
||||
|
||||
- array verify(string text, string signature [, string &plaintext])
|
||||
verifies the given text with the signature.
|
||||
To verify a clearsigned text, pass false as signature.
|
||||
if plaintext is passed, it is filled with the plaintext (the text without signature).
|
||||
This only makes sense for a clearsigned text
|
||||
|
||||
- string decrypt(string enctext)
|
||||
decrypts the given enctext
|
||||
see adddecryptkey
|
||||
|
||||
- string encryptsign(string text)
|
||||
encrypts and signs the given text with the keys, which are set with addencryptkey and addsignerkey
|
||||
|
||||
- array decryptverify(string text, string &plaintext)
|
||||
decrypts and verifies the given text and returns information about the result in an array
|
||||
the plaintext is passed into $plaintext
|
||||
|
||||
- string export(string key)
|
||||
returns the given key
|
||||
|
||||
- array import(string key)
|
||||
imports the given key and returns an array with informations about the import-process
|
||||
|
||||
- array listsignatures(string key)
|
||||
returns an array of informations about the keysignatures
|
||||
|
||||
- array deletekey(string key)
|
||||
deletes a key from the keyring. use with caution!
|
||||
|
||||
gnupg_keylistiterator
|
||||
---------------------
|
||||
This extension comes with an iterator for looping through the keyring
|
||||
see examples/keylistiterator.php
|
||||
if an argument is passed in the constructor, only keys that are matching this argument gets returned
|
||||
The documentation is now available in the PHP-Manual http://www.php.net/manual/en/
