The PGPKeyManager module manages individual PGP keys.

Syntax

SecureBlackbox.PGPKeyManager

Remarks

PGPKeyManager provides means for generating, checking, and editing individual PGP keys.

PGPKeyManager can work with RSA, Elgamal (DH), ECDSA, DSS, and EdDSA keypairs with or without subkeys. Public and private PGP keys of versions 2, 3, 4, 5, and 6 are supported.

Note: if you are looking to work with multi-key files ('keyrings'), please see the PGPKeyring component instead. PGPKeyManager works with individual PGP key structures ('key trees' - one primary key with subkeys). For that same reason, consider using PGPKeyring for loading keys that are to be used with PGPWriter and PGPReader for signing or encryption. It is often the case that even allegedly single-key files actually contain more than one key tree, which may lead to key material loss if they are loaded into PGPKeyManager.

Or, putting it in a simple way:

• Use PGPKeyManager if you need to alter a key (e.g. generate, add or remove subkeys, revoke, re-sign, change password).
• Where you need to use an existing key (e.g. for signing), use PGPKeyring, even if it is a standalone key.
• To alter a key residing in a keyring, load the keyring files into PGPKeyring first. The assign the key in question to PGPKeyManager, make the necessary changes, return it back to the keyring, and re-save the keyring.

You can load keys into a PGPKeyManager object in one of the following ways:

• By loading it from a file or memory using ImportFromFile or ImportBytes methods.
• By importing it from a PGPKeyring object using ImportPinned method.
• By generating it using GeneratePair or CreateKey methods.

• Iterate over elements of the key tree using Subkeys, Signatures, and Users collections.
• Add new subkeys to it using CreateSubkey method. Note that your new subkey is unlikely to be accepted elsewhere unless you sign it.
• Add new user records to the key with CreateUser method.
• Signing keys, subkeys, and user records (existing or new) with this or another private key using SignKey, SignSubkey, and SignUser methods. The new signatures are added to the key tree.
• Remove or revoke existing subkeys, user records, and signatures.
• Change the key protection level or password.

Note: Use pinning to copy keys between PGPKeyring and PGPKeyManager: Keyring.PinnedKey = Mgr.Key; Keyring.ImportPinned(); Mgr.PinnedKey = Keyring.SelectedKeys[i]; Mgr.ImportPinned(); Once your work with the key tree has completed, save it to a buffer or file using ExportBytes and ExportToFile methods.

- (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.

If you leave PreferredAlgs, no algorithm preferences information will be saved with the key.

The KeyFlags parameter is a bitmask that can contain the following bit flags:

SignUser Method (PGPKeyManager Module)

Creates a user certification.

Syntax

• Swift
• Objective-C

public func signUser(index: Int32, keyValidTo: String, hashAlgorithm: String, primary: Bool, certType: Int32) throws -> Void

- (void)signUser:(int)index :(NSString*)keyValidTo :(NSString*)hashAlgorithm :(BOOL)primary :(int)certType;

Remarks

Use this method to sign the user ID with the specified Index using the SigningKey. This signature creates a binding between the user ID and their main key.

While it is typical to sign user IDs with their own secret keys, occasionally third-party authentication is used where the binding is signed with a third-party key.

The KeyValidTo parameter indicates the expiration date of the binding. It can be different to that of the signing and/or the main key. The Primary parameter indicates whether this should be considered the primary user ID for this key (for example, if the user has more than one email). The CertType parameters indicates the type of binding, and should be set to one of the following values (if unsure, use pctGeneric):

Verify Method (PGPKeyManager Module)

Verifies the integrity of a key signature.

Syntax

• Swift
• Objective-C

Error Event (PGPKeyManager Module)

Information about errors during PGP key management.

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 key management.

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

KeyPassphraseNeeded Event (PGPKeyManager 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. The class fires it when it attempts to use a secret key to sign the data.

This event is fired for every protected secret key residing in SigningKeys. 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.

Notification Event (PGPKeyManager 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.

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).
