CheckPassphrase Method (PGPKeyManager Component)

Checks if the password matches the secret key.

Syntax

function CheckPassphrase(Passphrase: String): Boolean;

Remarks

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

Config Method (PGPKeyManager Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

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

function DoAction(ActionID: String; ActionParams: String): String;

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 of the action is provided in ActionID parameter. ActionParams contains a list of parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

ExportKey Method (PGPKeyManager Component)

Serializes the key to a byte array.

Syntax

function ExportKey(): TBytes;

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

function ExportPublicKey(): TBytes;

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

procedure ExportPublicToFile(Filename: String);

Remarks

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

ExportPublicToStream Method (PGPKeyManager Component)

Exports the public key to a stream.

Syntax

procedure ExportPublicToStream(Stream: TStream);

Remarks

Use this method to save the public key to the stream specified by Stream.

ExportToFile Method (PGPKeyManager Component)

Exports the key to a file.

Syntax

procedure ExportToFile(Filename: String);

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

procedure ExportToStream(Stream: TStream);

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

procedure 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

procedure GenerateLegacy(Username: String; Bits: Integer; Password: String; Expires: Integer);

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

procedure GeneratePair(Username: String; KeyAlgorithm: String; KeyBits: Integer; SubKeyAlgorithm: String; SubKeyBits: Integer; Password: String; Expires: Integer);

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:

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).

Expires
Integer

Indicates key expiration time in whole days from its generation moment. The value of 0 indicates that the key does not expire.

Handle
Int64

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());

HashAlgorithm
String

Specifies the hash algorithm associated with the key.

IsPublic
Boolean

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

IsSecret
Boolean

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

IsSubkey
Boolean

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

KeyFP
String

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

KeyHashAlgorithm
String

Specifies the hash algorithm used with DSA keys to calculate signatures.

KeyID
String

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.

OldPacketFormat
Boolean

Indicates whether legacy (PGP 2.6.x) packet format should be used.

Passphrase
String

The key protection password.

PassphraseValid
Boolean

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

PrimaryKeyID
String

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

Protection
TsbxPGPProtectionTypes

Specifies the level of protection applied to the secret key.

Allowed values:

pptNone0Key is not encrypted
pptLow1Only the password hash is used to derive the secret key

PublicKeyAlgorithm
String

Specifies the asymmetric algorithm of the key.

QBits
Integer

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.

Revoked
Boolean

Returns True if the key has been revoked, and False otherwise.

SubkeyFP
String

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

KeyFP could be used to distinguish two subkeys with the same SubkeyID.

SubkeyID
String

Contains a 8-byte subkey identifier.

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

Timestamp
String

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

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.

Valid
TsbxPGPKeyValidities

Indicates the validity status of the key.

pkvStrictlyValid0Strictly valid

pkvValid1Valid

pkvInvalid2Invalid

pkvFailure3Generic validation failure

pkvUnknown4Validity unknown

ValidTo
String

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

Version
Integer

Indicates the key version.

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

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

Constructors

>

constructor Create();

Creates an empty PGP key object.

Configuration Settings (PGPKeyManager 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.

PGPKeyManager Configuration Settings

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

Base Configuration Settings

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:

offNo caching (default)
localLocal caching (supported for HTTPClient, RESTClient and SOAPClient only)

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.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

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.
