Syntax

bool __fastcall CheckPassphrase(String Passphrase);

Remarks

Use this method to check if a password can decrypt the Key.

Config Method (PGPKeyManager Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

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

String __fastcall DoAction(String ActionID, String ActionParams);

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 insencitive) 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)

Serializes the key to a byte array.

Syntax

DynamicArray<Byte> __fastcall ExportKey();

Remarks

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

ExportPublicKey Method (PGPKeyManager Component)

Exports the public key to a byte array.

Syntax

DynamicArray<Byte> __fastcall ExportPublicKey();

Remarks

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

ExportPublicToFile Method (PGPKeyManager Component)

Exports the public key to a file.

Syntax

void __fastcall ExportPublicToFile(String Filename);

Remarks

Use this method to save the public key stored in Key to the file specified by Filename.

ExportToFile Method (PGPKeyManager Component)

Exports the key to a file.

Syntax

void __fastcall ExportToFile(String Filename);

Remarks

Use this method to save the Key (both the public and secret parts) to the file specified in Filename.

Generate Method (PGPKeyManager Component)

Generates a new single PGP key.

Syntax

void __fastcall 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

void __fastcall GenerateLegacy(String Username, int Bits, String Password, int Expires);

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

void __fastcall GeneratePair(String Username, String KeyAlgorithm, int KeyBits, String SubKeyAlgorithm, int SubKeyBits, String Password, int Expires);

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.
The code snippet below illustrates a typical key generation procedure: 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); Supported public key algorithms:

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.

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:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal 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).

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.

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.
