Config Method (PGPKeyManager Component)
Sets or retrieves a configuration setting.
Syntax
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These 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.
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.
DoAction Method (PGPKeyManager Component)
Performs an additional action.
Syntax
Remarks
DoAction is a generic method available in every component. 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;....
ExportKey Method (PGPKeyManager Component)

Syntax
Remarks
Use this method to save the Key (both the public and secret parts) to a byte array.

Exports the public key to a byte array.
Syntax
Remarks
Use this method to save the public key contained in Key to a byte array.

Syntax
public void ExportPublicToStream(System.IO.Stream stream);
Public Sub ExportPublicToStream(ByVal Stream As System.IO.Stream)
Remarks

Syntax
Remarks
Use this method to save the Key (both the public and secret parts) to the file specified in Filename.
ExportToStream Method (PGPKeyManager Component)
Exports the key to a stream.
Syntax
public void ExportToStream(System.IO.Stream stream);
Public Sub ExportToStream(ByVal Stream As System.IO.Stream)
Remarks
Use this method to save the Key (both the public and secret parts) to a stream pointed by Stream.
Generate Method (PGPKeyManager Component)
Generates a new single PGP key.
Syntax
public void Generate();
Public Sub Generate()
Remarks
Call this method after setting up relevant fields of Key to generate a new PGP key. This method generates a 'standalone' key without subkeys. Use GeneratePair to generate a pair of a main key and a subkey.
Most PGP implementations work with pairs of keys: the sign-only primary key and the encrypt-only (or encrypt-and-sign) subkey. If you need to generate a conformant PGP key to use with other PGP software, you likely need to use the GeneratePair method.
GenerateLegacy Method (PGPKeyManager Component)
Generates a new key in the old format.
Syntax
Remarks
Use this method when you need to generate an RSA key in the old (PGP 2.6.x) format.
Username specifies the user of the key, Bits is the key length in bits. Provide Password for the key and its expiration date and time via Expires.
Only use this method where you want to work with very old PGP software. While still providing a decent level of protection (subject to key length, of course), legacy keys are rarely used these days, and have almost everywhere been replaced with new-style keys.
Most modern PGP implementations work with pairs of keys: the sign-only primary key and the encrypt-only (or encrypt-and-sign) subkey. If you need to generate a conformant PGP key to use with other PGP software, you likely need to use the GeneratePair method.
GeneratePair Method (PGPKeyManager Component)
Generates a new pair of PGP keys.
Syntax
Remarks
Use this method to create a new 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.
Set KeyAlgorithm and SubKeyAlgorithm to the public key algorithms that you want to use for the new key. See the full list of algorithms below. Where ECDSA or ECDH algorithm is used, you can specify a particular curve after the algorithm name, separated with the colon: ECDSA:P384 or ECDH:BRAINPOOLP256. KeyBits and SubKeyBits specify the number of bits in the key and the subkey. These parameters can be set to zero if the key length is implicitly defined by the algorithm of the key. For example, ECDSA P256 keys are always 256 bit long, so you may pass 0 as the corresponding KeyBits or SubKeyBits parameter.
Provide the key encryption password and the validity period in days via the Password and Expires parameters. Set Expires to zero to indicate that the key does not expire.
While you can use any combination of algorithms for your key and subkey, most implementations got used to specific hard-wired combinations. Sticking to those will help make sure your keys are understood by other implementations. Typical combinations are:
- EDDSA main key with ECDH:CURVE25519 subkey;
- ECDSA main key with ECDH subkey; both with NIST curves (P256, P384, or P512);
- ECDSA main key with ECDH subkey; both with Brainpool curves (BRAINPOOLP256 or BRAINPOOLP512);
- RSA main key with RSA subkey.
Pgpkeymanager mgr = new Pgpkeymanager();
// generating a pair
mgr.GeneratePair("Michel Legrand <ml@email.com>", "EDDSA", 0, "ECDH:CURVE25519", 0, "password", 0);
// creating a keyring object and adding the new pair to the keyring
Pgpkeyring keyring = new Pgpkeyring();
keyring.CreateNew();
keyring.PinnedKey = mgr.Key;
keyring.AddPinned();
// exporting the keyring to a file
keyring.Save("pubkey.pkr", "seckey.skr");
Alternative calls to GeneratePair may look like this:
mgr.GeneratePair("Michel Legrand <ml@email.com>", "ECDSA:P384", 0, "ECDH", 0, "password", 0);
mgr.GeneratePair("Michel Legrand <ml@email.com>", "ECDSA:BRAINPOOLP256", 0, "ECDH:BRAINPOOLP256", 0, "password", 0);
mgr.GeneratePair("Michel Legrand <ml@email.com>", "RSA", 4096, "RSA", 2048, "password", 0);

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).

maxcount | Flush cached entries upon reaching LogMaxEventCount entries in the cache. |
Use this property to provide the desired debug log level.
Supported values are:
none | None (by default) | |
fatal | Severe errors that cause premature termination. | |
error | Other runtime errors or unexpected conditions. | |
warning | Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong". | |
info | Interesting runtime events (startup/shutdown). | |
debug | Detailed information on flow of through the system. | |
trace | More detailed information. |
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.
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 | |
keepolder | Keep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded) |
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.
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.
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.
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 |
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.
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.
Use this config property to store any custom data.
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.
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).
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).
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.
Set this global property to false to make each validation run use its own copy of system certificate stores.
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.
Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.
