PGPKeyring Component

Properties Methods Events Config Settings Errors

The PGPKeyring component manages PGP keyring files.

Syntax

TsbxPGPKeyring

Remarks

Keyring keep the details of local PGP key collections. A typical keyring consists of two parts, with the first part containing the public keys of other people, and the second part containing the secret keys of the keyring owner (i.e. your secret keys).

PGPKeyring 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.

Depending on your task at hand, you may need to only use the public part, or both. However, there is a couple of catches here. Some PGP implementations operate with just one keyring file that contains both the public and secret keys. The others sometimes mess-up the keys, with secret key accidentally ending up in the public part of the keyring, or the other way round.

Our suggestion therefore is to load all the keyring files that you have into PGPKeyring using consecutive ImportFromFile (or ImportBytes) calls, and then look for the keys that match the required parameters in the Keys collection. That would provide fault-tolerant and smooth experience to your customers. PGPKeyring keyring = new PGPKeyring(); keyring.ImportFromFile("pubring.pkr"); keyring.ImportFromFile("secring.skr");

Once you have loaded your keyring files into the keyring, you can perform the following operations on the keys:

Iterate over the whole set of keys using Keys collection.
Add new keys to the keyring using methods such as ImportBytes, ImportPinned, or ImportFromFile.
Save the updated keyring using ExportBytes or ExportToFile methods.
Use Select to filter keys by certain criteria (public/private, KeyID) into a separate SelectedKeys list.
Remove keys from the keyring.
Assign the keyring keys to properties like PGPWriter.SigningKeys to use them for encryption or signing.

Note: PGPKeyring provides access to keyring contents but does not let you edit or generate keys. To achieve these, please see PGPKeyManager.

Once you have completed your work with PGPKeyring, dispose of the object or call Reset to clean up all the key information from memory.

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 component, 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).

The following fields are available:

Fields

BitsInKey
Integer (read-only)
Default Value: 2048

Indicates the key length in bits.

CanEncrypt
Boolean (read-only)
Default Value: False

Returns True if this key can be used for encryption.

CanSign
Boolean (read-only)
Default Value: False

Returns True if this key can be used for signing.

Curve
String (read-only)
Default Value: ""

Indicates the elliptic curve associated with a EC key.

Supported values:


SB_PGP_CURVE_P256	`P256`
SB_PGP_CURVE_P384	`P384`
SB_PGP_CURVE_P521	`P521`
SB_PGP_CURVE_ED25519	`ED25519`

Enabled
Boolean
Default Value: False

Enables or disables this key for use in encryption or signing operation.

EncryptionAlgorithm
String (read-only)
Default Value: "AES128"

Indicates the symmetric algorithm used to encrypt the secret key.

Handle
Int64
Default Value: 0

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

IsPublic
Boolean (read-only)
Default Value: False

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

IsSecret
Boolean (read-only)
Default Value: False

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

IsSubkey
Boolean (read-only)
Default Value: False

Returns True if this key is a subkey of another key, and False otherwise.

KeyFP
String (read-only)
Default Value: ""

The 20-byte fingerprint (hash value) of this key.

KeyFP could be used to distinguish two keys with the same KeyID.

KeyID
String (read-only)
Default Value: ""

Contains a 8-byte key identifier.

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
Boolean (read-only)
Default Value: False

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

PrimaryKeyID
String (read-only)
Default Value: ""

If this key is a subkey (IsSubkey returns True), this property contains the identifier of the subkey's primary key.

Protection
TsbxPGPProtectionTypes (read-only)
Default Value: 0

Specifies the level of protection applied to the secret key.

Allowed values:


pptNone	`0`	Key is not encrypted
pptLow	`1`	Only the password hash is used to derive the secret key
pptNormal	`2`	Password hash with salt is used to derive the secret key
pptHigh	`3`	Hash from multiple passwords and salt are used for key derivation

PublicKeyAlgorithm
String (read-only)
Default Value: ""

Specifies the asymmetric algorithm of the key.

QBits
Integer (read-only)
Default Value: 0

The length of the DSA Q (legitimate range: 160-512).

This parameter corresponds to the hash algorithm used with the key. For example, if the value of Q is 256, SHA-256 will be used.

Timestamp
String (read-only)
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
Integer (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.

Constructors

constructor Create();

Creates an empty PGP key object.

Config Settings (PGPKeyring Component)

The component 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 component, access to these internal properties is provided through the Config method.

PGPKeyring 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.

UseLongKeyIDs: Enables long (8-byte) KeyID representation.

Switch this setting on to enable long (8-byte/16-char) representation of KeyIDs. The components use the abbreviated 4-byte/8-char representation by default.

Base Config Settings

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 component.

Supported values are:

Use this property to get cookies from the internal cookie storage of the component and/or restore them back between application sessions.

DefDeriveKeyIterations: Specifies the default key derivation algorithm iteration count.

This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

DNSLocalSuffix: The suffix to assign for TLD names.

Use this global setting to adjust the default suffix to assign to top-level domain names. The default is .local.

EnableClientSideSSLFFDHE: Enables or disables finite field DHE key exchange support in TLS clients.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies: Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the components that have its CookieCaching property set to "global".

HardwareCryptoUsePolicy: The hardware crypto usage policy.

This global setting controls the hardware cryptography usage policy: auto, enable, or disable.

HttpUserAgent: Specifies the user agent name to be used by all HTTP clients.

info		Interesting runtime events (startup/shutdown).
debug		Detailed information on flow of through the system.
trace		More detailed information.

LogMaxEventCount: Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

The default value of this setting is 100.

LogRotationMode: Specifies the log rotation mode.

Use this property to set the log rotation mode. The following values are defined:


none		No rotation
deleteolder		Delete older entries from the cache upon reaching LogMaxEventCount

MaxASN1BufferLength: Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth: Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm: Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

OldClientSideRSAFallback: Specifies whether the SSH client should use a SHA1 fallback.

Tells the SSH client to use a legacy ssh-rsa authentication even if the server indicates support for newer algorithms, such as rsa-sha-256. This is a backward-compatibility tweak.

PKICache: Specifies which PKI elements (certificates, CRLs, OCSP responses) should be cached.

The PKICache setting specifies which Public Key Infrastructure (PKI) elements should be cached to optimize performance and reduce retrieval times. It supports comma-separated values to indicate the specific types of PKI data that should be cached.

Supported Values:


certificate	Enables caching of certificates.
crl	Enables caching of Certificate Revocation Lists (CRLs).
ocsp	Enables caching of OCSP (Online Certificate Status Protocol) responses.

Example (default value): PKICache=certificate,crl,ocsp In this example, the component caches certificates, CRLs, and OCSP responses.

PKICachePath: Specifies the file system path where cached PKI data is stored.

The PKICachePath setting defines the file system path where cached PKI data (e.g., certificates, CRLs, OCSP responses and Trusted Lists) will be stored. This allows the system to persistently save and retrieve PKI cache data, even across application restarts.

The default value is an empty string - no cached PKI data is stored on disk.

Example: PKICachePath=C:\Temp\cache In this example, the cached PKI data is stored in the C:\Temp\cache directory.

ProductVersion: Returns the version of the SecureBlackbox library.

This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

ServerSSLDHKeyLength: Sets the size of the TLS DHE key exchange group.

Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

StaticDNS: Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the component. Works only if UseOwnDNSResolver is set to true.

Supported values are:


none		No static DNS rules (default)
local		Local static DNS rules
global		Global static DNS rules

StaticIPAddress[domain]: Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the component) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

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 component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component 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 chached 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 components.

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).

TLSSessionPurgeInterval: Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

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: 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: Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");

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