Data Type

Byte Array

KeyNonce Property (CryptoKeyStorage Component)

A nonce value associated with a key.

Syntax

__property DynamicArray KeyNonce[int KeyIndex] = { read=FKeyNonce };

Remarks

A nonce value associated with a key. It is similar to IV, but its only purpose is to introduce randomness.

This property is read-only and not available at design time.

Data Type

Byte Array

KeySymmetric Property (CryptoKeyStorage Component)

Returns True if the object contains a symmetric key, and False otherwise.

Syntax

__property bool KeySymmetric[int KeyIndex] = { read=FKeySymmetric };

Default Value

false

Remarks

Returns True if the object contains a symmetric key, and False otherwise.

Data Type

Boolean

KeyValid Property (CryptoKeyStorage Component)

Returns True if this key is valid.

Syntax

__property bool KeyValid[int KeyIndex] = { read=FKeyValid };

Default Value

false

Remarks

Returns True if this key is valid. The term Valid highly depends on the kind of the key being stored. A symmetric key is considered valid if its length fits the algorithm being set. The validity of an RSA key also ensures that the RSA key elements (primes, exponents, and modulus) are consistent.

The KeyIndex parameter specifies the index of the item in the array. The size of the array is controlled by the KeyCount property.

This property is read-only and not available at design time.

Data Type

Boolean

Opened Property (CryptoKeyStorage Component)

Indicates whether the storage is in the open state.

Syntax

__property bool Opened = { read=FOpened };

Default Value

false

Remarks

Use this property to check if the storage has been 'opened.' Different kinds of key storages imply different meanings for 'being opened', but generally a storage is open if it is available for operations.

Use Open method to open a storage.

This property is read-only and not available at design time.

Data Type

Boolean

PinnedKeyHandle Property (CryptoKeyStorage Component)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

The SelectedKeyIndex parameter specifies the index of the item in the array. The size of the array is controlled by the SelectedKeyCount property.

This property is read-only and not available at design time.

Data Type

Boolean

SelectedKeyValid Property (CryptoKeyStorage Component)

Returns True if this key is valid.

Syntax

__property bool SelectedKeyValid[int SelectedKeyIndex] = { read=FSelectedKeyValid };

Default Value

false

Remarks

Returns True if this key is valid. The term Valid highly depends on the kind of the key being stored. A symmetric key is considered valid if its length fits the algorithm being set. The validity of an RSA key also ensures that the RSA key elements (primes, exponents, and modulus) are consistent.

The SelectedKeyIndex parameter specifies the index of the item in the array. The size of the array is controlled by the SelectedKeyCount property.

This property is read-only and not available at design time.

Data Type

Boolean

StorageID Property (CryptoKeyStorage Component)

Syntax

__property String StorageID = { read=FStorageID };

Default Value

""

Remarks

Use this property to get a unique ID of this storage. The format of ID may differ for different kinds of key storages, and may range from a file path for a file storage, to a URI-like ID for a PKCS#11 storage, to an empty value for an in-memory storage.

This property is read-only.

Data Type

String

StorageLocation Property (CryptoKeyStorage Component)

Specifies the location of the currently opened storage.

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.

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.

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.
