# PGPKeyManager Module

The PGPKeyManager module manages individual PGP keys.

## Syntax

```text
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](PGPKeyring.md#PGPKeyring) component instead. PGPKeyManager works with individual PGP key structures ('key trees' - one primary key with subkeys). For that same reason, consider using [PGPKeyring](PGPKeyring.md#PGPKeyring) for loading keys that are to be used with [PGPWriter](PGPWriter.md#PGPWriter) and [PGPReader](PGPReader.md#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](PGPKeyring.md#PGPKeyring), even if it is a standalone key.
- To alter a key residing in a keyring, load the keyring files into [PGPKeyring](PGPKeyring.md#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](#importfromfile-method-pgpkeymanager-module) or [ImportBytes](#importbytes-method-pgpkeymanager-module) methods.
- By importing it from a PGPKeyring object using [ImportPinned](#importpinned-method-pgpkeymanager-module) method.
- By generating it using [GeneratePair](#generatepair-method-pgpkeymanager-module) or [CreateKey](#createkey-method-pgpkeymanager-module) methods.

```text
  Mgr.ImportFromFile("key.pub");
```

 Once you have the key loaded in your PGPKeyManager object, you can perform a variety of operations on it:

- Iterate over elements of the key tree using [Subkeys](#subkeys-property-pgpkeymanager-module), [Signatures](#signatures-property-pgpkeymanager-module), and [Users](#users-property-pgpkeymanager-module) collections.
- Add new subkeys to it using [CreateSubkey](#createsubkey-method-pgpkeymanager-module) 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](#createuser-method-pgpkeymanager-module) method.
- Signing keys, subkeys, and user records (existing or new) with this or another private key using [SignKey](#signkey-method-pgpkeymanager-module), [SignSubkey](#signsubkey-method-pgpkeymanager-module), and [SignUser](#signuser-method-pgpkeymanager-module) 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:

```text
  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](#exportbytes-method-pgpkeymanager-module) and [ExportToFile](#exporttofile-method-pgpkeymanager-module) methods.

## Syntax

```text
public func generatePair(version: Int32, username: String, strength: Int32, validTo: String, password: String) throws -> Void
```

## Remarks

Use this method to create a standard key-subkey pair. This is the primary method for generating conformant PGP keys.

Pass the user ID of the new key via the *Username* property. This typically should be in the format of *User Name <user@email>*, for example *Robert Frost <robert@frost.com>*, but generally can be an arbitrary text string.

# SignSubkey Method ([PGPKeyManager](#pgpkeymanager-module) Module)

Sign the key's subkey.

## Syntax

```text
public func signSubkey(index: Int32, keyValidTo: String, hashAlgorithm: String, preferredAlgs: String, keyFlags: Int32) throws -> Void
```

## Remarks

Use this method to sign the subkey with a given *Index* (create a 'subkey binding signature'). Provide the signing key in [SigningKey](#signingkey-property-pgpkeymanager-module).

Use the *KeyValidTo* parameter to specify the subkey validity period and *HashAlgorithm* to provide the signature hash algorithm.

The *PreferredAlgs* parameter is expected to contain a list of algorithms that the signer of the key prefers the senders to use when using the subkey that is being signed. This value can contain a comma-separated mix of symmetric, hash, and compression algorithms from the following lists:

Encryption algorithms:

- Plaintext
- IDEA
- 3DES
- Blowfish
- AES128
- AES192
- AES256
- Twofish256
- CAST5
- Camellia128
- Camellia192
- Camellia256

Compression algorithms:

- ZIP
- ZLIB
- BZIP2

Hash algorithms:

- MD5
- SHA
- RIPEMD160
- SHA224
- SHA256
- SHA384
- SHA512
- SHA3-256
- SHA3-384
- SHA3-512

Example: *Camellia256,Twofish256,AES256,ZLIB,SHA512*

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:

|  |  |  |
| --- | --- | --- |
| KeyFlagCertifyOtherKeys | 1 | The key can certify other keys |
| KeyFlagSignData | 2 | The key can be used to sign data |
| KeyFlagEncryptData | 4 | The key can be used to encrypt data (in transit) |
| KeyFlagEncryptStorage | 8 | The key can be used to encrypt data (at rest) |
| KeyFlagSplitKey | 16 | The key is part of a split key scheme |
| KeyFlagGroupKey | 32 | The key is part of a group key scheme |

# SignUser Method ([PGPKeyManager](#pgpkeymanager-module) Module)

Creates a user certification.

## Syntax

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

## Remarks

Use this method to sign the user ID with the specified *Index* using the [SigningKey](#signingkey-property-pgpkeymanager-module). 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):

|  |  |  |
| --- | --- | --- |
| pctGeneric | 0 | Generic certification of a User ID and Public Key packet. The issuer of this certification does not make any particular assertion as to how well the certifier has checked that the owner of the key is in fact the person described by the User ID. By default user certifications use Generic type. |
| pctPersona | 1 | Persona certification of a User ID and Public Key packet. The issuer of this certification has not done any verification of the claim that the owner of this key corresponds to the specified User ID. |
| pctCasual | 2 | Casual certification of a User ID and a Public Key packet. The issuer of this certification has done some casual verification of the claim of identity. |
| pctPositive | 3 | Positive certification of a User ID and a Public Key packet. The issuer of this certification has done substantial verification of the claim of identity. |

# Verify Method ([PGPKeyManager](#pgpkeymanager-module) Module)

Verifies the integrity of a key signature.

## Syntax

```text
public func verify(index: Int32) throws -> Bool
```

## Remarks

Use this method to validate a key signature. Provide the index of the signature as a parameter.

# Error Event ([PGPKeyManager](#pgpkeymanager-module) Module)

Information about errors during PGP key management.

## Syntax

```text
func onError(errorCode: Int32, description: String)
```

## 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](#pgpkeymanager-module) Module)

Requests a key protection password from the application.

## Syntax

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

## 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](#pgpkeymanager-module) Module)

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

## Syntax

```text
func onNotification(eventID: String, eventParam: String)
```

## 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).

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

 **isPublic** *Bool (read-only)*
*Default Value: False*

Returns True if this key is a public key, and False otherwise.

It is quite rare that IDs of two keys collide. If that happens, their fingerprints (KeyFP) can be used for distinguish between the keys. Please note that many PGP implementations show only 4 lowest bytes of the KeyID to the user.

 **passphrase** *String*
*Default Value: ""*

The key protection password.

 **passphraseValid** *Bool (read-only)*
*Default Value: False*

Use this property to check whether the specified  is valid and can be used to unlock the secret key.

*Default Value: ""*

Use this property to check the time the key was generated. The date and time are stored and retrieved in Universal Coordinate Time (UTC).

 **username** *String (read-only)*
*Default Value: ""*

Specifies the name of the user bound to this key.

The PGP username is typically represented with a full name and an email address, but generally can be any non-empty string.

 **validTo** *String (read-only)*
*Default Value: "0"*

Provide accurate expiration moment indication. This is different to expires property which only contains expiration time in days in old keys.

 **version** *Int32 (read-only)*
*Default Value: 0*

Indicates the key version.

The key version refers to the version of the public-key packet format as defined in RFC 4880.

Only four versions are currently allowed here: 3, 4, 5 and 6. It is recommended that all new keys are created with version of 6.

# Config Settings ([PGPKeyManager](#pgpkeymanager-module) Module)

 The class accepts one or more of the following *configuration settings*. Configuration 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](#config-method-pgpkeymanager-module) method.

### PGPKeyManager Config Settings

**Armor**: Enables or disables ASCII armouring.Adjust this setting to enable or disable ASCII armouring on the outgoing messages.

**ArmorBoundary**: Specifies the armour boundary/title.Use this setting to specify custom ASCII armouring titles that go after the -----BEGIN and -----END tokens.

**ArmorHeaders**: Specifies armour headers.Use this setting to provide custom ASCII armouring (PEM) headers that should be included in the output.

**HashAlgorithm**: The hash algorithm to use with the operation, when not accepted via a parameter.This configuration setting lets you specify the hash algorithm to be used with an operation that does not accept it via a method parameter.

**KeyFlags**: Specifies key flags for user certification signatures.Use this setting to pass a bit mask of key flags to the user certification signature:

|  |  |  |
| --- | --- | --- |
| KeyFlagCertifyOtherKeys | 1 | The key can certify other keys |
| KeyFlagSignData | 2 | The key can be used to sign data |
| KeyFlagEncryptData | 4 | The key can be used to encrypt data (in transit) |
| KeyFlagEncryptStorage | 8 | The key can be used to encrypt data (at rest) |
| KeyFlagSplitKey | 16 | The key is part of a split key scheme |
| KeyFlagGroupKey | 32 | The key is part of a group key scheme |

Use this property before calling the [SignUser](#signuser-method-pgpkeymanager-module) method. The config setting is cleared after each signing operation.

**KeyHashAlgorithm**: The hash algorithm associated with the key.This setting returns the hash algorithm associated with and inherent to the key (such as SHA1 for DSA keys, or SHA512 for EdDSA keys)

**PreferredAlgs**: Specifies preferred algorithms for user certification signatures.Use this setting to include a list of preferred algorithms in the certification signature. The algorithms may include symmetric, hash, and compression algorithms.

Example: AES256,SHA256,AES128,SHA512,ZIP,ZLIB,CAST5

**RawKeyFormat**: Specifies whether low-level key format should be used as input or output of an operation.This setting specifies whether to use the raw (low-level, such as PKCS#1) key format during import or export operation.

**RespectKeyUsage**: Enables policy-based key usage checks.Set this property to true to enable policy-based key usage checks. If set to false (the default value), the values of CanSign and CanEncrypt properties of the key objects are based on the underlying cryptographic algorithm capabilities only. If switched to true, the values of the properties also consider the content of the key flags extension included in the respective key signatures.

**SaveKeyTrust**: Tells the component to include the trust packets with the serialized keys.Enables or disables inclusion of trust markers in the output keyring files. The default value is true.

**SaveSecretKeySignatures**: Enforces saving of signature packets to the secret keyring file.By default, key binding and user ID signatures are saved with the public part of the PGP keyring, whereas the private part only contains the secret key material. Set this option to true to enforce saving of signatures alongside the private keys. This may be useful when storing the keyring as a single file instead of a public/private pair.

**SignatureCreationTime**: Indicates the signature creation time.Returns the signature creation time.

**SignatureExpirationTime**: Returns or sets the signature expiration time.Returns the signature expiration time.

**SignatureHashAlgorithm**: The hash algorithm of the signature.Use this setting to obtain the hash algorithm of the signature.

**SubkeyIndex**: Allows to select a specific subkey for certain operations.It is typical for PGP key trees to employ the same protection parameters and passwords for all the keys and subkeys contained in the tree. This config setting lets you select a specific subkey if you want to apply certain protection parameter exclusively to that subkey. For example, the following code will only change the passphrase on the subkey with the index of 2:

```text
  mgr.Config("SubkeyIndex=2");
  mgr.ChangePassphrase("oldpass", "newpass");
```

Note: set this property to -2 to apply the setting to the main key. The default value of -1 indicates that any protection operation applies to all keys and subkeys in the tree.

**UseLongKeyIDs**: Use full-length KeyID format.It is typical for implementations to use the lower 4 bytes of PGP key IDs. Set this property to true to switch to the full (8-byte) key ID format.

### Base Config Settings

**ASN1UseGlobalTagCache**: Controls whether ASN.1 module should use a global object cache.This is a performance setting. It is unlikely that you will ever need to adjust it.

**AssignSystemSmartCardPins**: Specifies whether CSP-level PINs should be assigned to CNG keys.This is a low-level tweak for certain cryptographic providers. It is unlikely that you will ever need to adjust it.

**CheckKeyIntegrityBeforeUse**: Enables or disable private key integrity check before use.This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

**CookieCaching**: Specifies whether a cookie cache should be used for HTTP(S) transports.Set this property to enable or disable cookies caching for the class.

Supported values are:

|  |  |  |
| --- | --- | --- |
| off |  | No caching (default) |

**StaticIPAddresses**: Gets or sets all the static DNS rules.Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If *StaticDNS* of the class is set to "*local*", the property returns/restores the rules from/to the internal storage of the class. If *StaticDNS* of the class is set to "*global*", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

**Tag**: Allows to store any custom data.Use this config property to store any custom data.

**TLSSessionGroup**: Specifies the group name of TLS sessions to be used for session resumption.Use this property to limit the search of cached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.

**TLSSessionLifetime**: Specifies lifetime in seconds of the cached TLS session.Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

**UseCRLObjectCaching**: Specifies whether reuse of loaded CRL objects is enabled.This setting enables or disables the caching of CRL objects. When set to true (the default value), the system checks if a CRL object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where CRL objects are frequently used.

**UseInternalRandom**: Switches between SecureBlackbox-own and platform PRNGs.Allows to switch between internal/native PRNG implementation and the one provided by the platform.

**UseLegacyAdESValidation**: Enables legacy AdES validation mode.Use this setting to switch the AdES component to the validation approach that was used in SBB 2020/SBB 2022 (less attention to temporal details).

**UseOCSPResponseObjectCaching**: Specifies whether reuse of loaded OCSP response objects is enabled.This setting enables or disables the caching of OCSP response objects. When set to true (the default value), the system checks if a OCSP response object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where OCSP response objects are frequently used.

**UseOwnDNSResolver**: Specifies whether the client components should use own DNS resolver.Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

**UseSharedSystemStorages**: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.Set this global property to false to make each validation run use its own copy of system certificate stores.

**UseSystemNativeSizeCalculation**: An internal CryptoAPI access tweak.This is an internal setting. Please do not use it unless instructed by the support team.

**UseSystemOAEPAndPSS**: Enforces or disables the use of system-driven RSA OAEP and PSS computations.This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

**UseSystemRandom**: Enables or disables the use of the OS PRNG.Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

**XMLRDNDescriptorName[OID]**: Defines an OID mapping to descriptor names for the certificate's IssuerRDN or SubjectRDN.This property defines custom mappings between Object Identifiers (OIDs) and descriptor names. This mapping specifies how the certificate's issuer and subject information (ds:IssuerRDN and ds:SubjectRDN elements respectively) are represented in XML signatures.

The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.

Syntax:

```text
Config("XMLRDNDescriptorName[OID]=PrimaryName,Alias1,Alias2");
```

Where:

OID: The Object Identifier from the certificate's IssuerRDN or SubjectRDN that you want to map.

PrimaryName: The main descriptor name used in the XML signature when the OID is encountered.

Alias1, Alias2, ...: Optional alternative names recognized during parsing.

Usage Examples:

Map OID 2.5.4.5 to SERIALNUMBER:

```text
Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");
```

Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS:

```text
Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS");
```

**XMLRDNDescriptorPriority[OID]**: Specifies the priority of descriptor names associated with a specific OID.This property specifies the priority of descriptor names associated with a specific OID that allows to reorder descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during signing.

**XMLRDNDescriptorReverseOrder**: Specifies whether to reverse the order of descriptors in RDN.Specifies whether to reverse the order of descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to true (as specified in RFC 2253, 2.1).

**XMLRDNDescriptorSeparator**: Specifies the separator used between descriptors in RDN.Specifies the separator used between descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to ", " value.
