Installation
|
||
------------
|
||
tar xvzf gnupg-x.y.tgz
|
||
cd gnupg_x-y
|
||
phpize
|
||
make
|
||
make install
|
||
|
||
This extension requires the gpgme library, which is available at http://www.gnupg.org/(en)/download/index.html#gpgme
|
||

|
||
Notes
|
||
-----
|
||
|
||
- This extension requires PHP 5.
|
||
It was tested with 5.0.5
|
||
|
||
- This is a beta version.
|
||
Don´t use it on production systems.
|
||
See this release more like a "preview" or something like that.
|
||
|
||
- This extension makes currently no write-operations on your keyring.
|
||
But a backup of them is always a good idea
|
||
|
||
- Only the Open_PGP protocol is currently supported.
|
||
This shouldn´t be a problem for the most people.
|
||
|
||
- extending this class is currently not tested.
|
||
|
||
- only 1 key per operation is currently supported.
|
||
so you can´t add x keys for encryption.
|
||
|
||
- 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)
|
||
|
||

Methods
|
||
-------
|
||
|
||
- __construct()
|
||
sets up a new gnupg object
|
||
( new gnupg() )
|
||
|
||
- 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
|
||
|
||
- bool setpassphrase(string passphrase)
|
||
sets the passphrase for all next operations
|
||
|
||
- 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 setsignerkey(string key)
|
||
sets the private key for the next sign operation.
|
||
please note, that the given key must return only 1 result from the keyring
|
||
it should be the best to provide a fingerprint here
|
||
|
||
- bool setencryptkey(string key)
|
||
sets the public key for next encrypt operation.
|
||
please note, that the given key must return only 1 result from the keyring
|
||
it should be the best to provide a fingerprint here
|
||
|
||
- bool clearsignerkey(void)
|
||
removes all keys which are set for signing
|
||
|
||
- bool clearencryptkey(void)
|
||
removes all keys which are set for encryption
|
||
|
||
- 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 &plaintext])
|
||
verifies the given clearsigned text and returns information about the result in an array
|
||
if plaintext is passed, it is filled with the plaintext (the text without signature)
|
||
|
||
- string decrypt(string enctext)
|
||
decrypts the given enctext
|
