- (NSString*)config:(NSString*)configurationString;

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DecryptAndVerify Method (PGPReader Module)

Syntax

• Swift
• Objective-C

public func decryptAndVerify() throws -> Void

- (void)decryptAndVerify;

Remarks

Use this method to unprotect a PGP message contained in a byte array (InputBytes), in a file (InputFile) or in a stream (InputStream). The method writes the decrypted message to a byte array (OutputBytes), to a file (OutputFile) or to a stream (OutputStream).

DoAction Method (PGPReader Module)

Performs an additional action.

Syntax

• Swift
• Objective-C

public func doAction(actionID: String, actionParams: String) throws -> String

- (NSString*)doAction:(NSString*)actionID :(NSString*)actionParams;

Remarks

DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

VerifyDetached Method (PGPReader Module)

Verifies a detached signature.

Syntax

• Swift
• Objective-C

public func verifyDetached() throws -> Void

- (void)verifyDetached;

Remarks

EncryptionInfo Event (PGPReader Module)

Reports early information on encryption parameters.

Syntax

• Swift
• Objective-C

func onEncryptionInfo(keyIDs: String, integrityProtected: Bool, passphraseUsed: Bool)

- (void)onEncryptionInfo:(NSString*)keyIDs :(BOOL)integrityProtected :(BOOL)passphraseUsed;

Remarks

The class fires this event to report early encryption information. Use this event to find out what encryption type is used, and to provide appropriate decryption material (the secret keys or the password) via DecryptingKeys or Passphrase properties.

KeyIDs contains the IDs of the keys that can be used to decrypt the data. PassphraseUsed shows if the message can also be decrypted with a passphrase. Both can be set at the same time, indicating that each of the decryption routes can be taken.

IntegrityProtected parameter specifies whether the message includes a modification detection record.

Error Event (PGPReader Module)

Information about errors during PGP decryption/verification.

Syntax

• Swift
• Objective-C

func onError(errorCode: Int32, description: String)

- (void)onError:(int)errorCode :(NSString*)description;

Remarks

The event is fired in case of exceptional conditions during decryption/verification of protected data.

ErrorCode contains an error code and Description contains a textual description of the error.

ExternalDecrypt Event (PGPReader Module)

Handles remote or external decryption.

Syntax

• Swift
• Objective-C

func onExternalDecrypt(operationId: String, algorithm: String, pars: String, encryptedData: String, data: inout String)

- (void)onExternalDecrypt:(NSString*)operationId :(NSString*)algorithm :(NSString*)pars :(NSString*)encryptedData :(NSString**)data;

Remarks

Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.

Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

Reports the ending of file extraction process.

Syntax

• Swift
• Objective-C

func onFileExtractionFinish(filename: String, timestamp: String)

- (void)onFileExtractionFinish:(NSString*)filename :(NSString*)timestamp;

Remarks

This event informs about the ending of extraction of the next available file. Filename parameter indicates the original file name, and the Timestamp its last modification time.

In the handler, the user can take away the output stream or store the file data from OutputBytes.

FileExtractionStart Event (PGPReader Module)

Reports the beginning of file extraction process.

Syntax

• Swift
• Objective-C

func onFileExtractionStart(filename: String, timestamp: String, skip: inout Bool)

- (void)onFileExtractionStart:(NSString*)filename :(NSString*)timestamp :(int*)skip;

Remarks

This event informs about the beginning of extraction of the next available file. A PGP message may contain more than one file. Filename parameter indicates the original file name, and the Timestamp its last modification time.

The user should provide an output filename in OutputFile or a stream in OutputStream. If none of them is provided, the extracted file will be placed to OutputBytes. After the file is extracted, FileExtractionFinish event is fired.

KeyPassphraseNeeded Event (PGPReader Module)

Requests a key protection password from the application.

Syntax

• Swift
• Objective-C

func onKeyPassphraseNeeded(keyID: String, userID: String, mainKey: Bool, passphrase: inout String, skip: inout Bool)

- (void)onKeyPassphraseNeeded:(NSString*)keyID :(NSString*)userID :(BOOL)mainKey :(NSString**)passphrase :(int*)skip;

Remarks

The class fires this event to request a secret key passphrase from the application. Note that this event asks for a key protection passphrase rather than a message protection passphrase (which is requested via PassphraseNeeded). The class fires it when it has found a suitable decryption secret key in the keyring, and attempts to use it to decrypt the data.

If the data is encrypted with multiple keys, this event is called for each key in a loop until the password for at least one key is provided correctly. KeyID specifies the key for which the password is requested, and UserID identifies its user. MainKey tells whether the key is a master key or a subkey.

The handler should provide password via the Passphrase parameter, or set Skip to True to skip this key.

For each key KeyPassphraseNeeded is called in a loop until the correct password is provided or the maximum number of password attempts reached.

MultipleFilesFound Event (PGPReader Module)

Fires if the PGP message is recognized to contain multiple files.

Syntax

• Swift
• Objective-C

func onMultipleFilesFound(tarFilename: String, proceed: inout Bool)

- (void)onMultipleFilesFound:(NSString*)tarFilename :(int*)proceed;

Remarks

The class fires this event to report that there is more than one file in the PGP message.

The TarFilename specifies the name of the TAR file containing the files. Tune up Proceed to go ahead or stop the processing.

Notification Event (PGPReader Module)

This event notifies the application about an underlying control flow event.

Syntax

• Swift
• Objective-C

func onNotification(eventID: String, eventParam: String)

- (void)onNotification:(NSString*)eventID :(NSString*)eventParam;

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

PassphraseNeeded Event (PGPReader Module)

Requests a data protection password from the application.

Syntax

• Swift
• Objective-C

func onPassphraseNeeded(passphrase: inout String, skip: inout Bool)

- (void)onPassphraseNeeded:(NSString**)passphrase :(int*)skip;

Remarks

The event is fired in a loop until the correct password is passed or the number of password attempts is exceeded.

Progress Event (PGPReader Module)

Reports the progress of the decryption operation.

Syntax

• Swift
• Objective-C

func onProgress(current: Int64, total: Int64, cancel: inout Bool)

- (void)onProgress:(long long)current :(long long)total :(int*)cancel;

Remarks

Notifies the application about a signed message.

Syntax

• Swift
• Objective-C

func onSigned(keyIDs: String, signatureType: Int32)

- (void)onSigned:(NSString*)keyIDs :(int)signatureType;

Remarks

The class fires this event when it identifies a signed message to allow the application to prepare the component for verification.

Use the KeyIDs parameter to identify keys used that were used to sign the message, and make sure they are available in the VerifyingKeys list.

SignatureType indicates the signature type:

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

Constructors

public init()

Creates a new ExternalCrypto object with default field values.

PGPKey Type

This container represents a PGP key.

Remarks

OpenPGP standard supports several types of keys. In our days, a typical OpenPGP keypair actually consists of two cryptographic keys: a primary key and a subkey. The primary key is normally used for signing, while the subkey is used for encryption.

While it is typical for PGP environments to use a primary key/subkey bundle, this is not a must. Sometimes you may come across standalone keys (mainly when dealing with older implementations), as well as whole key trees, each of those carrying a bunch of differently-purposed subkeys bound to the same primary key.

Algorithm-wise, OpenPGP keys also differ. Generally speaking, OpenPGP supports the following public key algorithms: RSA, Elgamal (often incorrectly referred to as DH), DSA, ECDH and ECDSA. When it comes to primary key/subkey bundles, DSA/Elgamal, RSA/RSA and ECDSA/ECDH pairs are typically used. Although there's no restriction on algorithm bundles, and, e.g. a ECDSA/Elgamal key bundle is perfectly possible, such combination is rarely used in practice.

A typical OpenPGP key is associated with some kind of user ID (Username). It is normally represented with a user's e-mail address, while in theory can be any piece of text. The secret part of the OpenPGP keypair is protected with a password (Passphrase).

Fields
