string decrypt(
string
$encrypted_data, string
$passphrase)

Decrypts string data using the given passphrase

This method assumes the required private key is available in the keyring and throws an exception if the private key is not available. To add a private key to the keyring, use the Crypt_GPG::importKey() method.

Return: the decrypted data.
Abstract:
Throws: Crypt_GPG_KeyNotFoundException if the private key needed to decrypt the data is not in the user's keyring.
Throws: Crypt_GPG_NoDataException if specified data does not contain GPG encrypted data.
Throws: Crypt_GPG_Exception if an unknown or unexpected error occurs. Use Crypt_GPG::$debug and file a bug report if these exceptions occur.
Throws: Crypt_GPG_BadPassphraseException if specified passphrase is incorrect or if no passphrase is specified.
Access: public

Overridden in child classes as:

Crypt_GPG_Driver_Php::decrypt(): Decrypts string data using the given passphrase

Parameters:

string	`$encrypted_data`	—	the data to be decrypted.
string	`$passphrase`	—	the passphrase of the private key used to encrypt the data.

void deletePrivateKey(
string
$key_id)

Deletes a private key from the keyring

If more than one key fingerprint is avaliable for the specified $key_id (for example, if you use a non-unique uid) only the first private key is deleted.

Abstract:
Throws: Crypt_GPG_KeyNotFoundException if a private key with the given $key_id is not found.
Throws: Crypt_GPG_Exception if an unknown or unexpected error occurs. Use Crypt_GPG::$debug and file a bug report if these exceptions occur.
Access: public

Overridden in child classes as:

Crypt_GPG_Driver_Php::deletePrivateKey(): Deletes a private key from the keyring

Parameters:

string $key_id — either the full uid of the private key, the email part of the uid of the private key or the key id of the private key. For example, "Test User (example) <test@example.com>", "test@example.com" or a hexidecimal string.

void deletePublicKey(
string
$key_id)

Deletes a public key from the keyring

If more than one key fingerprint is avaliable for the specified $key_id (for example, if you use a non-unique uid) only the first public key is deleted.

Abstract:
Throws: Crypt_GPG_KeyNotFoundException if a public key with the given $key_id is not found.
Throws: Crypt_GPG_Exception if an unknown or unexpected error occurs. Use Crypt_GPG::$debug and file a bug report if these exceptions occur.

string encrypt(
string
$key_id, string
$data, [boolean
$armor = true])

Encrypts string data

Data is ASCII armored by default but may optionally be returned as binary.

If this method throws a Crypt_GPG_MissingSelfSignatureException, the public key needs to be signed. Keys may be manually signed using the shell command:

gpg --sign-key &lt;key-id&gt; &lt;named-user&gt;

Return: the encrypted data.
Abstract:
Throws: Crypt_GPG_KeyNotFoundException if the a key with the given $key_id is not found.
Throws: Crypt_GPG_UnsignedKeyException if specified key is not signed.
Throws: Crypt_GPG_Exception if an unknown or unexpected error occurs. Use Crypt_GPG::$debug and file a bug report if these exceptions occur.
Throws: Crypt_GPG_MissingSelfSignatureException if specified key is not self-signed (verified by the user).
Access: public

Overridden in child classes as:

Crypt_GPG_Driver_Php::encrypt(): Encrypts string data

Parameters:

string	`$key_id`	—	the full uid of the public key to use for encryption. For example, "Test User (example) <test@example.com>".
string	`$data`	—	the data to be encrypted.
boolean	`$armor`	—	optional. If true, ASCII armored data is returned; otherwise, binary data is returned. Defaults to true.

[array
$options = null])

Creates a new Crypt_GPG object

Abstract:
Access: public

Overridden in child classes as:

Crypt_GPG_Driver_Php::__construct(): Creates a new GPG object that uses PHP's native process manipulation functions to control the GPG process

Parameters:

array $options — optional. An array of options used to create the GPG object. All options must be optional and are represented as key-value pairs.

[ Top ]

Crypt_GPG factory(
[string
$driver = 'php'], [array
$options = array()])

Static factory method to create a new GPG object using the specified backend driver

Return: a GPG object powered by the speficied driver.
Access: public

Parameters:

string	`$driver`	—	optional. The name of the driver to use. Valid driver names are 'php' for a native PHP driver and 'gnupg' for a PECL-powered driver. If not specified, the native PHP driver is used.
array	`$options`	—	optional. An array of options passed to the driver's constructor. All options must be optional and are represented as key-value pairs. See documentation of a specific driver for details on what options are available.

If more than one private key fingerprint is avaliable (for example, if you use a non-unique uid) only the first private key fingerprint is returned.

Only private key fingerprints are returned. See Crypt_GPG::getPublicFingerprint() to get the fingerprint of a public key.

Return: the fingerprint of the private key, or null if no fingerprint is found for the given private key identifier.

boolean	`$separator`	—	optional. A string placed between the public key fingerprint components to make the fingerprint easier to read. If not specified, the components of the fingerprint are not separated.
